Compressed Air Refill Near Me? All Answers

A compressed air tank, or “portable tank,” is a handy workshop or garage tool that allows you to store compressed air in a portable, easy-to-use unit. You fill up the tank with compressed air using any air compressor, then carry the tank to where you need it. Air tanks are most commonly used for inflating tires – on cars, bikes, trailers, ATVs, etc. – but they are also useful for blow-off tip applications. Its relatively light weight and size make a portable compressed air tank more useful than a portable air compressor in many situations. The tanks are typically too small to run air tools for more than a few quick surgeries.

What is a portable compressed air tank? A compressed air tank is a pressure vessel that keeps air compressed under pressure. This air is released via a valve as required. Although some air tanks can be stationary, they can also be portable.

Parts of a portable compressed air tank

The components of a portable compressed air tank provide all the features you need for easy and safe use. In these tools you will usually find the following components:

Air Fill Valve: The valve you connect to when you fill the tank with a compressor

the valve you connect to when you fill the tank with a compressor. Air Shutoff Valve: a knob that rotates to prevent air from escaping from the tank when not in use

a knob that rotates to prevent air from escaping the tank when not in use. Air pressure gauge: shows the air pressure in the tank and the level in the tank.

shows the air pressure in the tank and the filling level of the tank. Pressure vessel: the pressure vessel that contains compressed air

the pressure tank that holds compressed air Flexible hose: the hose used to supply compressed air from the tank, which can be attached with a threaded fitting or quick-release coupling

the hose for supplying compressed air from the tank, which can be attached with a threaded connector or a quick connector. Universal connector: a universal quick connector that allows easy changing of the hose type

Warning When filling a portable compressed air tank, pay close attention to the pressure gauge. You never want the pressure to exceed the manufacturer’s recommendation. You should also underfill the tank a bit to allow heat to expand the air without worrying about possible tank rupture.

How to use a portable compressed air tank

Understand Sizes Air tanks come in a variety of sizes, measured in gallons of compressed air. Common sizes are 5, 7, 9, 10, and 11 gallons. A 10 gallon or larger size is likely to be more useful for a variety of applications, while a small 5 or 7 gallon tank is very portable and takes up less space.

Estimate What Size You Need To estimate how tank capacity translates to practical air volume, remember that 7.5 gallons of tank volume equals 1 cubic foot of volume. A small car tire has a volume of about 1 cubic foot. That means a 7-gallon air tank doesn’t have enough capacity to fill a small car tire that’s completely flat.

Consider the Rating In addition to capacity, compressed air tanks have a maximum pressure rating, which is measured in pounds per square inch, or psi. Common values ​​range from 125 psi to over 150 psi. This rating indicates the maximum air pressure that the tank can safely handle. However, it is a good idea not to fill the tank to the maximum pressure level as air pressure increases with heat. For example, if you leave a tank out in the sun, the pressure in the tank will increase even without additional air. If the tank is completely filled, the pressure could exceed the rated pressure and cause a rupture.

Choose and Fill Your Compressor If you need compressed air in a remote location where there is no electricity to run a compressor, you can fill an air tank at home with an air compressor. If you don’t have one, you can use the compressor at a gas station or hardware store. Simply attach the fill nipple to the tank and use the compressor as usual to fill the tank slowly, watching the pressure gauge to make sure the pressure isn’t rising too fast or too high.

Carbon dioxide or CO2 is filled by moving the compressed liquid form of the gas from a larger tank into a smaller CO2 tank commonly used for paintball. The key to filling the smaller tank is finding a shop that stocks the larger tanks and has the appropriate equipment to fill the smaller tanks. The type and size of the tank to be filled plays a role when it comes to finding the most suitable place to fill up.

Paintball shops and fields

Smaller tanks (from around 9 to 24 ounces) used for airguns such as paintball guns are a popular size for CO2. One of the best places to fill up this type of tank is at a paintball shop or paintball field. Most shops and fields store CO2 and have all the proper equipment to fill sufficiently without overfilling your tanks.

sporting goods stores

Many local or national sporting goods stores frequently fill CO2 tanks for paintball guns. Sporting goods stores are easy to find and usually do a good job of filling tanks. However, if you let an inexperienced person help you, you risk overfilling your tank, which could result in a blown safety glass.

Many sporting goods stores also sell smaller, pre-filled canisters that make great paintball gun backups. These small canisters can also be found at most bike shops. Cyclists often wear them as a quick way to inflate a bicycle tire.

Fill tanks at home

If you use a lot of CO2, whether for paintball or another hobby, it can be worth having a large tank at home, along with the right supplies to fill smaller tanks. This can save you money in the long run and may also be more convenient.

tank swap

Similar to propane tanks for backyard grills, some stores that sell CO2 tanks also have tank exchange programs that allow you to turn in an empty tank and leave with another pre-filled one. While this is slightly more expensive than refilling a tank, it can be more convenient.

Other uses for CO2

Home brewing is growing in popularity, and one of the ways to add carbonation to beer is through forced carbonation. This process involves adding CO2 to draft beer over an extended period of time, as opposed to using sugar to naturally carbonate the beer. These types of CO2 tanks are much larger than the smaller ones used in airguns, as their size typically ranges from around 2.5 pounds to 20 pounds. Most stores that sell home brewing supplies should also be able to refill CO2 tanks.

CO2 tanks are also used in many home aquariums that maintain live freshwater plants. While plants can thrive in the right conditions without adding additional carbon dioxide to the tank, their health and growth benefit greatly from aquarium setups that involve the use of CO2. For this reason, many aquarium specialty stores are also equipped to refill aquariums.

Does Lowes fill CO2 tanks?

A few months ago we tested to find the best frame nailer. We also compared the best air compressors. We had a good time, but every single one of the pneumatic models would be useless without the unsung hero of this particular shootout: the air compressor. However, not everyone knows how to properly operate an air compressor. In this introduction to our Training the Apprentice series, we cover the basics.

Frame nailers aren’t the only tools that require pneumatic (air) energy to function. Instead of working with electricity, many tools in both the professional and DIY arsenals are powered by compressed air. Compressed air plays a major role in construction, mechanical and painting applications. In short – don’t skimp on this tool!

If you’re just learning how to use an air compressor, don’t stress yourself. It’s effortless to learn, and once you’ve gone through the process a few times, it will seem like second nature.

Editor’s Note: Be sure to also check out our pick for the best portable air compressor for your home garage

How to Use an Air Compressor – Initial Setup

Let’s start by checking the oil. Most smaller air compressors these days don’t require oil to operate, but the larger ones probably will. Regardless of size, before you start your air compressor, check the manual to make sure your compressor uses oil and where it goes.

If your compressor needs oil to run, chances are you’ll find the dipstick near the bottom of one of the ends of the compressor. Pull it out and check the oil level, just like your car’s engine oil. Add more when it gets low.

In some cases, such as For example, on our 80-gallon NorthStar compressor, the manufacturer provides an easy-to-read window in your oil reservoir. Compressor oil is available at most home improvement, auto parts, and hardware stores.

When the oil in your compressor’s oil window looks milky like this, it’s time to replace it.

Using a gas powered air compressor requires fuel

If you’re using a gas-powered air compressor, try using ethanol-free gasoline or something like TruFuel premix. It will help your compressor last longer. If you absolutely must use regular gas, add an ethanol-specific fuel stabilizer like Stabil.

You may also need a break-in period to keep it running at its best. Check the manual for the type of break-in procedure you should use with a new compressor. A good rule of thumb is to open the drains and then run the air compressor for 30 minutes.

When using an electric air compressor, be mindful of your cord length

Obviously, an electric air compressor needs electricity – so plug it in. If possible, avoid using extension cords on AC models unless a working electrical outlet is nearby where you intend to work. Incorrect extension cords can cause the compressor to overheat. It is better to connect multiple air hoses together to bring air to your tool.

If you’re not sure what type of extension cord to use with your air compressor, see our Extension Cord Size Chart for reference.

Attach your hose to the regulator

Attach your hose to the control valve. It’s the valve next to the pressure gauge on the compressor. This part should be fairly easy to figure out, but your hose has a male connector while your compressor has a female connector.

You must push in the moving part of the coupling so that the end of the hose can be connected. If the compressor contains air, some will be released when you lock the hose in place and you’ll feel it being pushed back.

At the other end of the hose you have the same type of connector. The tool has a male shank that attaches to the adapter at the end of the hose.

Test the safety valve

Pull the safety valve. You should be able to find it near the hose assembly. If you tug on it and hear air hiss, you’re in good shape. Push the valve back into place before starting the compressor. If you don’t hear any air escaping, but you can put the valve back in place, you’re probably still fine.

Turn on the compressor and fill the tank

Turn on the compressor and wait until the tank is full. You’ll know you’re ready to get to work when the needle on the tank gauge stops moving forward and the engine stops.

Find out how much air pressure your tool needs to work properly. Usually this information is printed on the bottom of the tool. If you can’t find it on the tool, the manual certainly has that information. Each tool has a different PSI value. So if you change the tool, you also need to adjust the hose pressure.

However, PSI is not the only consideration. You should also check the SCFM requirement or how much airflow the tool needs. Tools like nailers only require a short burst of air, while something like an air grinder requires a constant, high-level flow of air.

Adjust the air regulator

For this next step you need to adjust the regulator knob. One direction (usually clockwise) gives you more pressure, while the opposite direction decreases it. It only takes a few seconds for the compressor to stabilize. Don’t be afraid to make small adjustments until you have it where you want it.

Every time you use your power tool, the tank pressure drops as the compressed air flows through the hose to your tool. If the pressure in the tank gets too low, the compressor starts up again and refills the tank.

However, PSI is not the only consideration. You should also check the SCFM requirement or how much airflow the tool needs. Tools like nailers only require a short burst of air, while something like an air grinder requires a constant, high-level flow of air.

Know your duty cycle

Every compressor has a duty cycle. This is the working speed that the engine can handle without risking damage. Some compressors can have a 100% duty cycle, which means you can use them non-stop all day if you want.

Others may have a 50% duty cycle. If you use it for 5 minutes, it needs a 5-minute break. Air compressors with less than 100% duty cycle often indicate how long they can run (e.g. 10 minute intervals).

Servicing your air compressor

You need a rest at the end of the day and your compressor needs to decompress too.

Drain the tank

When you finish your work, you need to open the drain valve at the bottom of the tank to drain moisture. This needs to be done after each use as water and metal don’t usually get along for long. Where we are in central Florida, there is a bit of salt in the air, which speeds up the rusting process. Because the rust starts on the inside of the tank, you won’t notice it until brown water comes out.

First turn off the compressor. When you open the drain valve, the escaping air also pushes out moisture that collects at the bottom of the tank. Alternatively, turn the pressure control knob to turn off the air supply to the hose and turn off the compressor. Then wait for the pressure to leave the compressor. You can pull the pressure release valve to deflate faster. However, this does not release the moisture.

Keep an eye on the air filter

Get in the habit of checking the air filter every time you use it. Too much gunk will start to starve the engine and can cause it to stall. Replace it when you start to see a significant amount of debris on it.

Check the oil again

After stowing the hoses, take this opportunity to recheck the oil and replace it if it’s gone too low. Once a year you should completely replace the oil. Consult your manual for the best way to do this.

Air tanks have a lifespan

Air compressor tanks have a finite lifespan. While draining the tank will help expand it, there is ultimately a risk of it bursting. Refer to the data label to determine when to replace the air canister.

How to fill a water pressure tank with a tire pump or compressed air source ASK a QUESTION or COMMENT on how to add air to a water filled water pressure tank – how to decide which air refill pressure to use: air volume control, filling air at an air valve or emptying the water tank .

InspectAPedia does not tolerate conflicts of interest. We have no relationship with any advertiser, product or service discussed on this site.

To fill the water pressure tank with air by pumping the air inlet valve:

This article describes how to add air to a building’s water pressure tank and how to detect and repair air and water leaks in a building’s water supply system when the water source is a private well.

We also provide an INDEX OF ARTICLES for this topic, or you can try the SEARCH BOX at the top or bottom of the page to quickly find the information you need.

Method 2: Pump air into the water tank using the Schrader valve

Here we explain how to use a simple hand pump (or an air filled cylinder) to bring the air charge back into a water tank.

The procedure outlined below works to add air to either type of water tank: a bubble type tank with trapped air (photo below) or a bubbleless steel water pressure tank. Our photo on the left shows an air inlet valve located on the tee at the bottom of the water tank.

This method of adding air to the water tank is for water tanks that do not use an internal bladder.

While it is often necessary to correct the air charge in a bladderless water tank, bladder type water tanks will not normally lose air and will not normally need to increase the air pressure in the tank unless there is a leak in the tank itself or a defect in the water carrying bladder in the tank Tank.

Bladder-type water tanks, or “captive air” water tanks (see photo below), typically do not need to add supplemental air.

When water tanks with bladders have water pump problems and the problem is not in the pump controller or the water line, the problem can be traced to a failure of the internal bladder of the water tank itself.

If the water-carrying rubber bladder in a “captive air” water tank is defective (it may stick to itself and remain collapsed), this can result in rapid on-off short cycling of the water pump. We test water pressure tanks to see if they are empty or almost empty by seeing if we can rock or move the tank. When the water tank is heavy with water, it will not move easily.

Be careful not to wiggle and break a pipe! Bladder type or trapped air water pressure tanks and their repairs are described just above and in more detail

for WATER TANK TYPES .

Most water tanks, both captive bladder and non-bladder steel tanks, have a fitting that looks like a tire valve that is located at the top of the tank, possibly at the bottom of the tank, or on the water outlet line, which is usually at the bottom of the tank .

In the photo shown on the left, the blue cap on the top of a bladder type internal water tank marks the location of the air valve for that water tank.

This valve really can be almost anywhere near the water tank on a pipe that pumped air would rise up into the water tank as it is used to add air pressure to the system. Look for a small valve stem that looks like a tire valve. In fact, it’s a tire valve.

These air intake valves are technically called “Schrader valves” in case you need to buy a new one. The stem is about 3/16″ in diameter and maybe 1.5″ to 2″ long. It might have a valve cap on it that looks just like what’s on your car.

That’s because it’s actually the same device used for car and truck tires.

Caution: On some pressurized water tanks, what appears to be an ordinary, simple air inlet valve may be a snifter valve instead. The snifter valve stem looks like any other air intake valve. It’s different and probably won’t let you pump air into the water tank.

Only used on submersible well pump systems, snifter valves are a type of automatic air volume control system that attempts to add a small amount of air to the water pressure tank during each well pump duty cycle. We inform about snifter valves

at AIR VOLUME REGULATOR, WATER TANK

Our photo (left, Rasmussen Well Drilling, Inc., Two Harbors MN & DJ Friedman) shows a snifter valve air intake mounted on a bronze check valve.

How to recognize that a snifter valve is installed on a well water system:

If the air inlet valve you find is mounted on a check valve (usually on the well plumbing just before the water pressure tank inlet port) and your fountain system uses a submersible pump and bubbleless water tank, you may not be able to get air into the water pressure tank through that valve – The check valve can prevent air from entering the water tank.

If the snifter valve is not working (often the valve is clogged with rust or debris from either the air valve or the vent drain on the well plumbing), you will need to add air to the water pressure tank by draining the tank or mounting an air valve directly onto a faucet on the water tank.

See also explanation and definition of the snifting valve

at AIR VOLUME REGULATOR, WATER TANK

Step-by-step instructions on how to add air to a water pressure tank using the air inlet valve

1. Stop the running water in the house and turn off the fountain pump

Turn off the power to the water pump or well pump.

2. Find the location of the air inlet valve on your water system. You may need to close the water valve between the tank and the building.

If the air valve is mounted directly on the water tank itself, you do not need to close the water supply shut-off valves for this operation.

If the air inlet valve is mounted on a tank tee at the bottom of the water tank, the process will go better if you close the main water supply valve between the water tank’s outlet line and the building it supplies.

If the air inlet valve is mounted to a check valve located on the well piping itself, you likely have a combination snifter valve and check valve, meaning that a particular air valve will not direct air into the water tank, but will let air into the well piping itself .

The next time the fountain pump is switched on, this air is pushed up into the water tank. Snifting valves and check valves are discussed

for AIR FLOW REGULATOR, WATER TANK,

You do not need to empty the water tank to use this procedure.

3. You can exit the water tank at any point in the pump on-off cycle and tank pressure that is present.

You do not need to drain water from the tank for this procedure.

4. Find the air inlet valve on your water tank and remove the cap.

Check the condition of the valve. No water should leak out.

If the water tank air inlet valve is leaking, you may be able to stop the leak by briefly depressing the center pin in the valve to flush the valve seat. Otherwise you will need to replace the valve stem core (it’s a tire valve stem that can be easily bought at any auto parts store). Details on repairing a leaking air valve are

at WATER TANK AIR VALVE REPAIRS .

Our photo (left) shows a Schrader valve on the outlet tee at the bottom of a water tank.

5. Pump air into the water pressure tank while observing the pressure gauge of the water tank.

We recommend only adding 5-10 psi of air to the tank initially.

If you have a bike pump, you can just clip the pump end to this valve and pump air into the tank without worrying about another tangle. But be prepared to do some pumping. An alternative is to use a portable air compressor such as those sold at auto supply stores for re-inflating car tires. We also used a portable air tank that we refilled from a nearby gas station or from a more powerful construction site air compressor.

Caution: Do not pressurize the water tank too much. Exceeding the safe working pressure of the water tank may rupture causing serious injury or death.

If you watch the pressure gauge on the water tank and keep the pressure at or below the gauge cut-out pressure (usually 40 or 50 psi), or below 70 psi if your tank was completely full of water at the beginning of the procedure and the pump had just shut down, you should be fine.

Caution: Some water pressure gauges do not work or are slow to respond to pressure changes. The gauge inlet, which measures water pressure, may be clogged with dirt. If your water pressure gauge isn’t changing steadily as water (or air) enters or leaves the water tank, try tapping the gauge lightly. If it still doesn’t work,

see WATER PRESSURE GAUGE

and WATER PRESSURE GAUGE ACCURACY – or replace the gauge with a new one.

WATER TANK AIR HOW MUCH TO ADD describes in more detail how much air to add to the system.

6. Turn on the power to the fountain pump again.

If the pressure in the water tank is below the cut-in pressure of the pump, the pump starts running immediately. If the pressure in the water tank is above the cut-in pressure, nothing will happen until you drain some water (and pressure) from the water pressure tank.

7. Turn on a nearby, convenient plumbing fixture (such as a kitchen sink or washbasin).

If you closed the main water valve between the water tank and the building in step 2, open that valve before attempting to run water.

Let the water run in the house until the fountain pump starts. Turn off the water at the faucet again and let the pump run until it reaches its cut-off point. At this point, both your water tank and building plumbing will be at cut-off pressure.

Turn the water on again at a suitable point and let it run. Notice how long the water runs or how much water runs before the pump turns on again. We’re looking for a 20-30 second setback time before the fountain pump turns back on when a typical kitchen faucet is running.

7. Evaluate the results. Add more air if needed.

If the drawdown cycle (time before the pump turns on again) is still too small (just a gallon or two is not enough) or timed (just a few seconds is certainly not enough time), then you should give the system more supply air.

8. What if you add too much air?

As long as you haven’t pressurized the water tank to unusually high (dangerous) levels, if the water tank is overfilled with air, excess air will usually leak out of the tank through the home water supply lines and fittings when it’s next run.

Since other problems (e.g. a leak in well pipes) can also cause air to leak from plumbing fixtures, we are providing more details

Repairing a Leaking Water Tank Air Inlet Valve: Tips for Water Tanks with Leaking Air Inlet Valves

If you tampered with this valve when there was no pressure on the water tank (perhaps you pushed the little pin at the top of the valve), water or air may leak out of the Schrader valve when you try to turn it back down to put pressure on the tank.

Details on repairing a leaking air inlet valve on a water tank can be found here

at WATER TANK AIR VALVE REPAIRS . For the sake of simplicity, we’ll repeat a few highlights just below.

Usually you can stop this water or air leak by simply pushing down on the small valve stem pin and releasing it a few times. This measure can successfully remove deposits that may have been on the valve seat.

The end of the valve stem that you push on looks like a small wire sticking out from the middle of the Schrader valve.

If all else fails, run to your car and borrow one of the tire valve caps and just screw them tight over the leaking Schrader valve.

This works well for stopping a water or air leak until you get a plumber or handyman to put a new valve stem in the misbehaving little valve.

Tools for replacing an air valve stem or an air valve core

In fact, the internal moving parts of this valve can be replaced in the same way as a car tire. You can buy valve stem cores (and the tools to replace them) at any auto parts store.

The special tool, sometimes simply a special valve stem cap, has a protruding tip with a slot in it that is used to unscrew and remove the old valve (located at the bottom of the valve stem itself and ending with the little pin you see if you look up into the valve stem) and screw in a new valve stem insert.

The replaced internal water tank air valve stem part (valve stem core) can be purchased with different spring rates for different pressure ranges, but given that the pressure range of a typical water tank is 20-70psi (like a car tire) almost any standard tire valve stem core would work well as a replacement, if your valve stem won’t stop leaking.

Questions and answers for readers – see also the FAQ series linked below

Question: Water is dripping from the air valve at the bottom of the tank

I have a hot water system with an oil burner. My expansion is dripping water from the air valve stem at the bottom of the tank should I repair or replace – Mike s 10/12/12

Answer:

Mike, an air valve stem is interchangeable, I would try that first.

Also check for abnormal system pressure (an unsafe condition). But if the tank’s internal bladder has burst – another explanation for finding water on the air pressure adjustment valve – then you most likely need to replace the tank. You know this condition because the tank gets soaked and heavy and eventually the boiler TP valve drips (another unsafe condition).

Meat is actually packed with CO2 as well as various gas mixtures. Some inhibit bacterial growth, while others slow oxidation and the loss of the bright red color. Nitrogen is commonly used with CO2 to achieve this in “counter ready” beef packaging. Pork sausage is protected with a mixture of 20% CO2/80% N2. Gas companies sell product lines specifically for meat, and the segment is often referred to as Modified Atmosphere Packaging or something similar. CO has applications in this area, but the dominant gases used to protect meat products are CO2 and N2.

Also, CO2 comes from the same bulk tank and through the same lines into the gas packaging facility. Bottles are commonly exchanged for service, whether industrial or beverage. They are usually kept in continuous operation by convention as this facilitates crop production, but this is not required.

Quality control is done in two ways. The first is the selection of the final source gas. For example, if you want to use CO2 for drinks, the gas comes from an ethanol plant. The CO2 plant is located on-site where ethanol is produced and passes through the raw product, which is essentially a by-product of ethanol production. The CO2 is refined to a desired level and includes the removal of moisture and the expected known impurities from the ethanol plant. It is then liquefied for easier storage and transportation. As the CO2 is generated, the production stream is continuously sampled to meet specifications. The CO2 plants produce products to meet the demand of the largest customers, therefore any plant that produces CO2 for beverage applications and supplies, for example, to Coke, produces products that meet this specification. So it certainly fulfills what you need it for as well. The truck transporting the product will likely be owned, but this is not required. A similar situation exists for medical O2, USP quality. The facility makes it, ships it in any old O2 truck (they’re all super clean anyway) and puts it in the same tank that we fill with weld and cut grade industrial oxygen. (It has always interested me that medical grade oxygen, USP, has a lower minimum purity requirement than industrial oxygen. There are strict controls over the USP filling process that protects patients using the gas, but the specification is in the Usually the lowest percent cleanliness. ) Plant piping is selected for pressure and cleanliness and may be brass of a particular type, stainless tubing or even monel. (Acetylene plants use black iron pipes.)

CO2 is sourced from other plants, some of which may contain ammonia as a trace contaminant, as well as other bad actors. As expected, beverage product does not come from there.

So the first control is exercised when we choose the source of the gas. The next check comes from conventional gas quality instruments such as the use of gas chromatography, IR spectroscopy, flame ionization hydrocarbon analysis and trace O2 analysis. The CO2 classes can be: Industrial, Bone Dry (really!), Super Critical Fluid, USP, Research, 2.8, 3.0, 4.0, (Numbers refer to how many “nines” percent purity), Instrument, Laser, etc. Oh , and drink quality too. It is worth noting that the gas supplier is free to market however they wish except for medical grades, USP and NF which are mandated by the FDA. So, a company’s offer may name a variety with similar nomenclature, but the specifications will be different.

The quality is controlled by selecting the sources and then doing the analysis. If you want to know what you’re getting, ask for a data sheet for the gas, which states the minimum guaranteed purity for any CO2 sold under whatever grade by the gas company. This is a catalog specification only. If it’s from a gas company like Praxair, Air Liquide or Linde, this information is easy to find on their websites. If you source a product from a retailer, the good guys will easily offer that too. If they can’t get a better source, then who can. NuCO2 is a national beverage gas supplier that was bought by Praxair some time ago and specializes in Bev Carb. In general, it’s best to tell your gas supplier what you’re going to be used for and ask what type you should be using and why. A good example is Praxair’s Wersite and Beverage Carbonation.

Hope that helps.

The main difference between compressed air and CO2 is that the pressure of compressed air is much higher than normal atmospheric pressure, while we usually store carbon dioxide at low pressure.

The atmosphere consists of different gases and particles that we need for different purposes. Oxygen is one of the most important things on earth that determines the survival of living beings. Apart from that, carbon dioxide is also essential for survival due to its importance in photosynthesis. Aside from these natural phenomena, humans have developed methods to use the air to meet their various needs.

What is compressed air?

Compressed air is air under pressure, consisting of oxygen, nitrogen, carbon dioxide and all other gases in the atmosphere. Also, this air is at a higher pressure than normal atmospheric pressure. It has many uses, mainly in power generation. However, it is more expensive than the other energy-producing resources like electricity, water, and natural gas.

More importantly, we can use compressed air as a method of storing energy. When we compress air, a lot of heat is released, and the air gets warmer after it’s compressed. Decompression of air requires heat. Therefore, we can store the heat generated during compression and use it later during decompression.

In addition, compressed air is useful for vehicles, railway braking systems, starting diesel engines, cleaning electronic equipment, pneumatic tools, etc. Compressed air tanks are expensive and require an advanced regulator to maintain a constant flow of air at the same pressure.

What is CO2?

Carbon dioxide is a molecule made up of one carbon atom and two oxygen atoms. Each oxygen atom forms a double bond with carbon and thus the molecule has a linear geometry. The molecular weight of this compound is 44 g mol-1.

Carbon dioxide (CO 2 ) is a colorless gas and forms carbonic acid when dissolved in water. In addition, this gas is denser than air. The concentration of carbon dioxide in the atmosphere is 0.03%. The carbon cycle balances the amount of CO 2 in the atmosphere. In addition, this gas is released into the atmosphere through natural processes such as respiration, volcanic eruption, and through human activities such as burning fossil fuels in vehicles and factories.

In contrast, during photosynthesis, this gas is removed from the atmosphere and they can be deposited as carbonates over the long term. However, human intervention (burning of fossil fuels, deforestation) causes an imbalance in the carbon cycle and increases CO 2 gas levels. Global environmental problems such as acid rain, the greenhouse effect and global warming are the result. Carbon dioxide is useful in the production of soft drinks, in the bakery industry, as a fire extinguisher, etc.

In addition, carbon dioxide tanks are readily available and we can easily buy them. Also, they cost less. As a result, their maintenance is easy and does not require an advanced controller. Carbon dioxide can be stored as a liquid at low pressure. However, they are unreliable at low temperatures.

What is the difference between compressed air and CO2?

Compressed air is the air under pressure made up of oxygen, nitrogen, carbon dioxide and all other gases in the atmosphere and CO 2 is a gaseous molecule made up of one carbon atom and two oxygen atoms. The main difference between compressed air and CO2 is that the pressure of compressed air is much higher than normal atmospheric pressure, while we usually store carbon dioxide at low pressure.

In addition, compressed air is more expensive than carbon dioxide. Another key difference between compressed air and CO2, the carbon dioxide tanks are easy to find and do not require advanced controls like compressed air tanks.

Compressed air is commonly used as an effective energy transfer medium in both domestic and industrial processes. This air is used as stored compressed air in air tanks or generated directly with air compressors. Depending on your use of compressed air, a key question that is often asked is the difference between air tanks and air compressors.

Compressed air tanks (or air receivers) are primarily compressed air storage vessels that supply compressed air to an application on demand. Air compressors, on the other hand, convert air pressure into compressed air to power applications or store in air tanks.

This article provides you with a comprehensive comparison of the use, size and cost of air tanks and air compressors. Knowing the differences between them will help you decide which one to choose for your compressed air needs.

Air Tanks and Air Compressors: Operation and Functions

The function of air tanks and air compressors is the same when it comes to transferring energy through compressed air.

However, air tanks and air compressors differ in how they work in transferring compressed air energy.

Air tank operation and functions

Air tanks are portable compressed air storage that you can easily carry around for simple applications.

They are widely used in workshops and garages and are used by vehicle owners to inflate tires.

To use an air tank, fill it with compressed air from an air compressor or garage near you. If necessary, you then suck the compressed air from compressed air tanks via the blow-off valve or the pressure relief system and use it in applications.

The possible uses of compressed air tanks include:

compressed air storage

Inflating tires and other inflatable items such as air mattresses and balloons

Air compressor support to allow compressor controllers to provide a consistent air signal

Operational support in secondary plants (plants that regulate, protect, monitor and control primary plants)

Unlike air compressors, ordinary small air tanks can only perform a few simple operations before you need to refill them.

Air compressor operation and functions

An air compressor compresses air and converts air pressure into usable energy. In this way, it supplies air to devices or applications.

They are often used in larger machines such as refrigerators and industrial applications because of their ability to compress large volumes of air and deliver it to an application.

That doesn’t mean you can’t use an air compressor for a simple task like inflating a tire. However, air compressors are more cumbersome and difficult to move. Therefore, an air compressor is heavier than an air tank of the same tank capacity. Air compressors also require a source of energy to run.

Some air compressors have an attached air tank. A good example is the California Air Tools 8010A air compressor, which you can purchase from Amazon.com. The tool has a:

Large 8 gallon aluminum tank

Fast universal connector

Wheel set for easy transport

To use an air compressor, open the air intake to allow air to flow into the cylinder. Once the air is in the cylinder, it is pressurized and forced through the exhaust valve into an air tank, air tool, or application.

Specific applications of air compressors include:

Inflating tires and other inflatable boats

Cooling air in air conditioners, freezers and refrigerators

Pumping water at high pressure in water jets and high-pressure cleaners

Underwater breathing support for scuba divers

Powering airbrushes when spray painting

Driving industrial processes such as packaging and transport, grinding, positioning and cutting

Operation of workshop equipment such as impact wrenches, nail guns, grinders, grinders and drills

Controlling heating and cooling in vehicle engines, train and truck brakes, and parking drives

Powering construction machinery, including hammers, drills and compactors

Control of water and water features in water fountains

Power supply for hospital equipment in the fields of dentistry, disinfection and oxygen supply

Firing ammunition in paintball and air guns

Driving agricultural equipment such as field sprayers

Integrated use of air tanks in air compressor systems

In large industrial applications, air tanks are often coupled with air compressors as part of a compressed air system.

Combining an air tank with an air compressor will help with:

Creation of temporary storage and an additional source of compressed air to ensure that there is sufficient air when the demand for compressed air in an application increases.

Maintaining constant pressure and stable compressed air flow.

Stabilizes the air demand of the compressor to keep up with air demand and prevents excessive engine wear due to overload.

Catch and drain condensate from the compaction process.

Overall, one could imagine combining air tanks and air compressors to optimize efficiency in an industrial facility.

However, air tanks used in air compression systems are much larger than the small portable air tanks used by car owners or small workshops.

Differences in size between air tanks and air compressors

Given that air tanks and air compressors work differently, it’s obvious that their sizes vary as well.

Size differences between air tanks and air compressors are characterized by their tank volume capacity (in gallons), the amount of compressed air they can store/produce, and pressure capacity (in PSI).

With air compressors, the air flow rate and horsepower also differ from one air compressor to another.

air tank sizes

Compressed air tanks come in different sizes, measured in gallons of compressed air. Standard air tank sizes include:

Five gallons (18.9L)

Seven gallons (26.5L)

Nine Gallons (34L)

Ten gallons (37.8L)

11 gallons (41.6L)

A 10 gallon (37.8 L) air tank is likely to be more useful for some applications, while a smaller 5 or 7 gallon (18.9 or 26.5 L) tank is only suitable for small applications, although lightweight and easy to clean to handle is to carry.

Air tanks used in large operations and those integrated with industrial air compressor systems can be thousands of gallons. In other words, the size of an air tank depends on the type and application.

For example, if you need an air tank to inflate a small car’s flat tire, you should choose one larger than 7.5 gallons (28.4 L) for two reasons:

First, a subcompact tire has a volume of one cubic foot, which is 7.5 gallons (28.4 L).

Second, heat increases air pressure. Therefore, you should not fill an air tank, as it can explode if the air pressure increases.

The size of air tanks is measured not only by their volume capacity but also by their pressure rating.

Air tanks have a maximum pressure rating, which is the maximum air pressure that the air tank can handle without posing a risk.

The maximum air pressure of air tanks is measured in pounds per square inch (PSI), and most air tanks are rated between 125 and 175 PSI (861.8 kPa and 1206.6 kPa).

sizes of air compressors

While you can consider the physical size of your air compressor for practical reasons of portability and use, you should not size the air compressor based solely on its physical size or gallon capacity.

Instead, consider these three measurements for more accurate sizing:

Air Compressor PSI (pounds per square inch)

The PSI of an air compressor is its pressure capacity, or the force with which it can deliver compressed air.

Air compressors used for pneumatic tools are typically rated at 70-90 PSI (482.6-620.5 kPa). Other high pressure air compressors are rated at 135 PSI (930.8 kPa).

Air pressure CFM (cubic feet per minute)

The CFM of an air compressor is its air flow rate, or the amount of compressed air it can produce at a given pressure level.

Compressors with higher CFM ratings can produce more compressed air, making them ideal for larger operations.

Air Compressor HP (Horsepower)

An air compressor’s horsepower is its horsepower, or the working capacity of the engine. Typically, the HP of an air compressor is rated between 1.5 and 6.5. Larger industrial air compressors can have up to 15 hp.

When considering an air compressor, its HP rating is not as crucial as its CFM and PSI rating, as more horsepower does not necessarily mean better air compression.

Also, today’s state-of-the-art air compressor models can do more with less horsepower, which means less energy consumption, higher efficiency and longer life.

Cost of air tanks and air compressors

Comparing the cost of air tanks and air compressors can be difficult. This is because both are mainly created and used in different applications.

Different air tanks have specific uses. Some are for:

inflatable boats

Power pneumatic tools

paintball launch

Air compressors have more functions than air tanks, which can mean higher costs. Also, some air compressors do smaller amounts of work and others do larger amounts of work.

In comparison, you will pay more for an air compressor than for an air tank, even if the volumetric capacity of an air compressor is less than that of an air tank.

For example, a 6 gallon air compressor can range in price from $100 to $200. However, you can easily find a 10-gallon tire inflator air tank for about half that price.

Air Tank vs. Air Compressor: Which Should You Buy?

Depending on the type of work you plan to do with either device, consider getting an air tank or air compressor. Get an air tank if you need compressed air for smaller jobs, and an air compressor for larger jobs.

To break it down for you, if you need inflatable boat compressed air, a simple air tank will do the job for you.

However, air tools such as wrenches, nail guns, grinders, grinders and drills, as well as high-energy operations such as cutting, positioning and packaging in large industries require an air compressor.

If you have a high-energy tool, consider pairing an air compressor with an air tank to improve efficiency.

Choosing between an air tank and an air compressor also depends on your budget. As mentioned earlier, air compressors cost a lot more than air tanks.

But cost shouldn’t outweigh purpose and function when deciding whether to go with an air tank or air compressor.
