Can you connect carbon filter directly to inline fan?

We don’t recommend mounting the fan directly onto the filter, as the vibration of the fan can cause settling of carbon in the filter. This settling may allow air pockets in the carbon to develop at the top, and untreated air to pass through the filter.

Are inline fans better at pushing or pulling?

Inline extraction fans are commonly designed to be positioned close to exit vents so that they extract (or suck) air from a room. However, when used as part of an air-cooled lighting system, it’s preferable to push air over your lamps that is, your inline fan is positioned before your air-cooled reflectors.

Do you need ducting for carbon filter?

Depending on your particular setup, fans and carbon filters can be attached to flexible ducting, rubber coupler, or rigid pipe, and can be mounted either inside or outside the grow area.

Which inline fan is best?

How long do carbon filters last?

Carbon filters should be replaced after 18-24 months of continuous (24/7) usage. Although this may vary depending on the company product, it has been shown that carbon filters can last for up to four years. These filters’ lifespan is largely dependent on their carbon quality, use, humidity, and plant type.

Does carbon filter go inside outside grow tent?

We recommend installing your carbon filter at the beginning of your ducting route. That is, placing it inside of your grow tent where your ductwork begins. This is a common set up, especially among those who use metal halide or HPS grow lights with duct ports.

Can I run multiple inline fans in series?

Many custom-designed setups require more ventilation than a single fan can deliver, so this can prompt the question whether two (or pairs of two) fans should be placed in series or parallel operation. In general, combining axial fans in series does not increase the airflow but increases the air pressure.

How far can you duct an inline fan?

Standard wall mounted axial fans are designed to be ducted straight through the wall and most struggle on duct runs over 4 metres. Any duct run of that length usually has bends in it too. Inline fans can comfortably sit on duct runs of up to 10m – and remember, the extraction rate is far higher to start with.

Are inline duct fans worth it?

A properly-designed HVAC system—which includes the vents and ductwork—should provide sufficient heating and cooling throughout the house, regardless of distance from the heating and cooling systems. While duct booster fans do boost airflow in specific areas, they don’t solve the underlying problem.

What size carbon filter and fan do I need?

The best way to figure out which size carbon grow room filter you should use is to make sure that your filter’s CFM value is either equal to or lower than the CFM value of your grow room and your exhaust fan. For example, say you have a 5ft x 5ft x 8ft grow tent: Multiply 5x5x8.

Do carbon filters actually work?

Carbon air filters can be effective at filtering VOCs from the air. These are gaseous substances that most other mechanical filters like HEPA filters, cannot touch. Some of the gases in cigarette smoke or those given off by drying paint or cleaning products can be removed from the air by a carbon filter.

How many fans do I need in my grow room?

As you learn how to vent a grow room, keep in mind that your grow room ventilation set up needs two types of fans. Keeps room and leaf temperatures down; smooth and…

What’s the quietest inline fan?

What size fan for 4×4 grow tent?

So for a 4×4 grow tent with an area of ~106 cubic feet, a grow tent fan (inline fan) rated for ~215cfm would get the job done.

Where do you put a carbon filter in a grow tent?

The Most Recommended Location. We recommend installing your carbon filter at the beginning of your ducting route. That is, placing it inside of your grow tent where your ductwork begins. This is a common set up, especially among those who use metal halide or HPS grow lights with duct ports.

How do you use a carbon filter in a grow tent?

Place the fan and filter above or near your plants. Next, position the fan so it pulls air from your grow room and exhausts it into the filter. This setup will make sure that all of the molecules in the air will pass through your carbon filter before any air leaves your grow room.

How to Set Up a Can-Fan / Can-Filter Combo

CAN-FAN / CAN-FILTER COMBO SETUP SUGGESTIONS:

You can set CAN-FAN / CAN-FILTER combos up in several different ways.

You can push or pull air through the filter, but the outer poly wrap is intended as a pre-filter to remove dust before it gets to the carbon, so it’s better to draw air up through the filter. The carbon inside will last longer with a clean pre-filter. The pre-filters are pretty cheap to replace, but you can hand wash them too as needed.

MOUNTING FAN AND FILTER:

We don’t recommend mounting the fan directly onto the filter, as the vibration of the fan can cause settling of carbon in the filter. This settling may allow air pockets in the carbon to develop at the top, and untreated air to pass through the filter.

You can hang the fan from a couple of rubber bungee cords to absorb any vibration and cut down on fan noise. Then connect the fan to the filter with standard clothes dryer ducting (from a hardware store) securing them together with either duct tape or screw-clamps.

The filter can then be placed in a dry location either sitting on the floor, or hanging from a ceiling. The length of ducting between the fan and filter doesn’t matter as long as the ducting is a clean, unrestricted shot between the two.

Straight PVC pipe can also be used for longer distances if necessary. For maximum effectiveness, the closer the filter is to the fan, the better, and we’d recommend keeping them within a few feet of each other. You can get some distance between them if you have to but it cuts down on the air speed.

AIR FLOW OPTIONS:

There are two really good ways to use the CAN combos.

The first is as a ‘polishing’ filter where you put the connected fan and the filter into the same area together. By drawing air through the filter repeatedly in a closed area, it will effectively keep the air in that area free of odors. This is how they use CAN filters in airplanes, and in other closed environments.

The second way to use the CAN combo is as a pre-exhaust air cleaner to remove odors from the air as you exhaust air from your garden area to another room. You’ll need a hole in a wall somewhere for this setup in order to exhaust the cleaned air out. All of the air that passes out of the room through the filter will be clean air. This setup is effective enough to use the heat from your growroom to help heat your home and not have to worry about organic fertilizer odor issues in the house. They use CAN filters this way in hospitals, auto body shops, chemical plants, and many other commercial applications.

Remember, that in every exhaust application, you have to have an unrestricted intake somewhere in the enclosure. If you run an exhaust fan without another fan for intake (not always necessary), or without a passive intake (a hole) somewhere in the room, you may run into heat issues. Any exhaust fan is going to need an intake in order to work to it’s best ability. A rule of thumb is that if you have one 6″ exhaust fan, you should have the equivalent of 2- 6″ holes for passive intake somewhere else in the enclosure or room.

GENERAL INFO:

All CAN-FILTERS last from 1 to 1-1/2 years – occasionally longer.

The higher your humidity, and the dustier the environment, the shorter the life of the filter.

To prolong the life of your equipment, clean the poly pre-filter regularly, and every once in a while shake or roll the filter around to expose new carbon within the filter.

Your CAN-FAN will last for many years. We’ve been selling these fans for about 6 years now, and have never had a warranty issue yet.

If you find that you need any additional fertilizer odor control try ONA PRO Gel. It’s a good compliment to the CAN Combo if needed.

Inline Fans & HID Cooling

Setting Up an Air-Cooled Grow Light-The Right Way!

Air-cooled grow lights open up some really interesting parts of the plant world to the indoor gardener. But there’s also a lot of confusion about how to set them up right.

Air-cooled grow lights are all about offering maximum light intensity without all the associated heat issues. Some plants such as those native to high altitudes in the sub-tropics only really thrive in lots of light and relatively cool temperatures these conditions are more challenging to recreate efficiently indoors. They also allow year-round indoor gardening with less need for additional air-conditioning during the warmer months. It’s more efficient to tackle the heat when it’s concentrated at its source rather than waiting until it has entered the room. This makes it easier to regulate the temperature of your indoor garden without over-ventilating and running the risk of reducing relative humidity levels or sucking out supplemental CO2 before it’s had a chance to be utilized by your plants.

The high intensity discharge (or HID) lamp is housed within a special air-cooled reflector.

Air-cooled reflectors work by allowing cool air to be passed across the lamp during operation. The most common designs feature a horizontally mounted lamp with flanges either side to allow cool air to be ducted in and warm air out ducted out. Some designs are based on a vertically mounted lamp. In both cases the central principle is the same: use a constant flow of air to move heat from the lamp and reflector and get it out of your indoor garden.

To get the air moving you’re going to need to connect an inline extraction fan to the reflector. Many growers ask whether they should place their extractor fan before the reflector so that it pushes cool air over the lamp, or after the reflector so that itpulls the warm air out? Others ask if it makes any difference at all?

Cooler air is better at cooling!

Common sense should tell you that the cooler the air you use, the more effective the cooling. Ideally you should take your air from a dedicated input either a cool adjacent room or from a shady outdoor wall and duct directly to your air-cooled reflector. Use a flange, ducting and jubilee clips to create an air-tight seal. While it’s important to have your ducting as straight as possible, remember to give yourself enough slack so that you can move your grow lights up and down. The expelled air from the air-cooled reflector should be ducted straight out of your indoor garden, preferably via insulated ducting for maximum efficiency after all, we want to whisk that heat away before it gets a chance to warm up your garden. The key thing here is to think of your air-cooled lighting ventilation as a separate system from your garden’s ventilation. Don’t take short cuts and attempt to combine your garden’s ventilation with your air-cooled grow light’s ventilation. Simply drawing the air from your garden through your reflectors may give you less ducting to worry about but it will give you markedly less efficient cooling because this air is probably already in the high 70s Fahrenheit.

Push or Pull?

Growers use inline fans to create the air-flow over the lamp. Using an inline air filter will protect your reflector and lamp from dust and other particulates, so it’s really best practice to use them. Inline extraction fans are commonly designed to be positioned close to exit vents so that they extract (or suck) air from a room. However, when used as part of an air-cooled lighting system, it’s preferable to push air over your lamps that is, your inline fan is positioned before your air-cooled reflectors. Not only does blowing cool air create less wear and tear on your fan’s motor than sucking warm air all the while, but you will enjoy more control over air movement in and around your garden. Blowing creates a positive pressure inside your air-cooled lighting ventilation system. If there are any leaks then air will spill into your garden and be dealt with by your garden’s ventilation system. Pulling, on the other hand, creates a negative pressure inside your air-cooled lighting ventilation system, so any leaks will draw your garden’s unfiltered air in.

Positioning inline fans can be tricky. Some growers fix them directly to wall flanges but vibrations can be an issue. In this case you can suspend them from the ceiling instead.

You should replace your lamps every six to nine months. Disconnect the power supply and unscrew the glass cover. This reflector has quick-release screws that make your life much easier. If the lamp has recently been in operation wait at least half an hour to allow it to cool. Next, unscrew the lamp screw turning anti-clockwise. Screw in the new lamp clockwise into the fitting using a cloth or piece of tissue paper to avoid getting fingerprint marks on the lamp. Replace the glass cover and tighten. Quality air-cooled reflectors are well sealed for maximum efficiency.

Using a jubilee clip, secure the ducting to one of the ports on the reflector it doesn’t matter which side and attach the other end of the ducting to the blowing (air exit) end of your 6″ inline fan. Remember, the fewer bends in your ducting, the more efficiently your fan will operate.

When air-cooled lights are set up right they can remove up to 50% of the heat generated by the grow lamp. But remember there are two types of heat associated with horticultural lighting. The physical heat generated from the lamp itself and the radiated heat in the form of infra-red light. Air-cooling only counteracts the build-up of physical heat. It does not affect the infra-red output. So, while you can certainly position air-cooled lights closer to your plants, growers still need to be aware of the importance of not overheating the canopy.

The glass panel in air-cooled reflectors does absorb some of the light (particularly UV) – so it’s important to keep your reflector’s glass panel clean and free of dust and finger marks. On the plus side it provides extra safety and, of course, you can significantly reduce the distance between your grow lights and your plants to exponentially increase light intensity and the incident energy hitting your plants’ leaves. In short, you can position air-cooled grow lights closer without stressing or burning your plants! As mentioned earlier, this is great for plants that require really intense levels of light but delivered at relatively cool temperatures.

Rule of thumb for positioning air-cooled reflectors:

Horizontally mounted 1000W lights are typically placed 24 – 36″ above the plant canopy.

Air-cooled horizontally mounted 1000W lights can be dropped as low as 8 – 12″ above the plant canopy.

TIP: Use an infra-red thermometer to monitor the surface temperature of your plant canopy leaves (those closest to the grow lamp) – the temperature should never read above 82 Fahrenheit / 28 Celsius)

Finally, a quick word on setting up multiple air-cooled grow lights. You can link them up in series like this, but inevitably the reflector at the end of the series is going to be warmer than the reflector at the beginning. Typically you shouldn’t link up more than two 6″ air-cooled reflectors or four 8″ reflectors. For maximum cooling efficiency, bring in one mainline cool air duct and use T-pieces and ducting serve each light individually. Use the same principle for extracting the air.

How to Set Up a Carbon Filter for Ideal Odor Control

Grow rooms need good ventilation to keep cool, fresh air coming in and warm, moist “used” air going out. But indoor growing can produce unwanted and even potentially toxic odors and contaminants from soils, fertilizers and the plants themselves. Since the exhaust air often flows into an adjacent indoor area, adding activated carbon filters to your airflow system is the best way to control odors and contaminants. Here’s how to set up a carbon filter for ideal odor control to clean your air while maintaining efficient airflow.

The place for your filter is in the exhaust system. Can-Lite activated carbon filters mount easily to Can-Fan and Max-Fan exhaust fans for long-lasting, consistent filtering performance with minimal resistance to cause airflow loss. Can-Lite fans and filters can be hung from grow tent supports or attached to solid surfaces in rooms with walls or ceilings.

The filter should be mounted on the intake side of the fan to remove contaminants before they reach the fan housing. Can-Lite filters come with pre-filters to keep dust, mold, and other particles from clogging the activated charcoal in the filter itself, so you should be pulling air through the filter rather than pushing air into it.

You may have both supply and exhaust fans, depending on the size of your grow operation. Even smaller rooms or tents that draw fresh air from the surrounding area may need an exhaust fan to carry away hot, stale air and an intake vent or fan to bring in fresh. Ideally, in an enclosed grow space the fresh air supply will be near the bottom of the area and the exhaust will be near the top. This takes advantage of the fact that hot air rises and cooler, denser air accumulates lower. As the warm, moist air is exhausted, fresh air will flow in across the plants to take its place.

10 Best Inline Fans For Your Grow Room In 2022

When growing indoors, your grow room ventilation is extremely important. Because most grow rooms or tents are enclosed and in tight quarters, without the right inline fan you’re looking at overheating your growing area and thus killing your plants.

Here are our top picks for inline fans as of right now, along with some crucial info on how to select one that best fits the size of your grow rooms or tents.

3. AC Infinity Cloudline T6

Where the Cloudline S6 shines, this truly excels. On top of the speed controller, fan speed controller, and other features of the S6, this adds even more customization on its fully digital controls. A backup system keeps its memory sharp so it remembers the custom speed settings you input. A countdown system and alarm timer help you keep track of its status. There’s an eco-mode setting for when you’re trying to reduce your power usage. And even better, the T6 can share its smart controller with the older S6 model so they can both operate on the same upgraded programming.

But there is one problem. The newer T6 model appears to have some occasional glitches in its alarm setup, and occasionally goes off for no reason. If you’re using the alarm to notify you of an increase in heat or humidity, you may find that an annoyance. As amazing as the updates are, the S6 is still a better buy for your money at least until they do a software upgrade for the T6.

Pros:

Temperature and humidity controller included

With a full line of fans to meet your needs, All…

A durable, ceramic-coated metal housing provides the framework upon which this sturdy fan is built. Like all of the Active Air series from Hydrofarm, it’s built with high-quality components and made to last. Low noise output makes this a refreshingly quiet way to keep the airflow cycling or to vent excess humidity.

None of the Hydrofarm systems have a speed controller included, but they’re available for a small additional fee. The only downside to this particular 8” model is that, as with many of the Hydrofarm fans, they’re meant to use rigid ducting. A flexible duct material is extremely difficult to connect.

Pros:

Quiet operation

Reliable manufacturer with a great reputation

Comes with all installation components as a plug-and-play unit

Cons:

No speed controls are included, although available at added cost

Really should be used with non-flexible ducting

I’m not going to claim that AC Infinity’s Cloudline is for everyone… but for those who want it, it’s perfection. The power cord for all of their Cloudline models is a good length, making it easy to install in grow rooms or tents. Truly made as inline duct fans, they’re easily connected to both flexible or rigid ductwork.

Like the other models, this one comes with all mounting equipment. However, they’ve changed from a smart controller to a humidity controller in the box, likely due to the T6 alarm issues.

Pros:

Fan speed fully adjustable from slight breeze to high wind conditions

Built in the United States, made to last

Cons:

No longer comes with a smart controller – has a humidity controller instead

Higher price point than other inline fans

6. Vivosun 8″ Inline Fan

Are you just getting started and need a cheap inline fan for your operation? The Vivosun may not be one of the best inline fans on the market, but it’s a perfect starting point. Its inexpensive price makes it a great value for low-budget grow rooms, especially if you’re just looking for an air intake fan.

The drawbacks to a low price, however, may stall the proficient user. It’s got a short cord, which makes it a bit more difficult to connect up with ease. Carbon filtration is not an option, as it’s just not powerful enough to support it. And every so often, users have encountered poor motor operation upon testing a new unit – although, to their credit, they’re quick to replace faulty devices.

For someone who’s just starting out, this is a good way to go as you learn what works best in your growing environment.

Pros:

Very reasonably priced

All-metal construction

Works well as an intake fan

Cons:

Not designed for use with a carbon filter

Short power cord

Some users have experienced faulty motors out of the box

8. iPower 10″ Inline Duct Fan

The iPower line of fans is a good mid-range series of inline fans. It doesn’t come with all of the bells and whistles in one neat package, so if you’re looking for more than just a fan, this may disappoint. Extremely bare-bones, you’re likely to get a corded fan in this box and little else.

But having said that, the fan tends to have a reasonably decent lifespan and may be slightly easier for a beginner to install. It is noisier than most of the others on the list, but that may not be a drawback if you’re venting an outdoor greenhouse. My largest complaint with this fan is the composite blades and hub, as I prefer metal, and even that’s a small quibble.

Pros:

Fluted at both ends for attaching ducting

Can be used with carbon filtration

Very reasonable price

Cons:

Slightly noisier fan than others we’ve covered

Fan blade and hub are composite rather than metal

10. iPower 12″ Inline Duct Fan

The same benefits and negatives of the 10” iPower apply to the 12” fan. A bit noisier than most of the fans on our list, it’s still a decent product. It’s bare-bones straight out of the box, so don’t expect any fancy bells or whistles. But its fluted shape is easy to hook up to your system, and the price for this fan size is great.

Pros:

Fluted shape makes it easy to hook into your duct system

Carbon filters are available for this fan

Reasonable price for its size

Cons:

Composite fan blade/hub instead of metal

Noisier than other makes of fan

Selecting The Right Inline Fan

Choose the best inline fan for your CFM needs.

When growing indoors, you’re controlling the entire environment. Light, temperature, humidity…and ventilation. While it’s important to know what the best grow lights are for your garden, many growers forget about ventilation and how much it can affect a grow. Here are some factors to take into consideration when choosing inline fans.

Why Is It Important To Get Inline Fans?

Without proper grow room ventilation, you’re dooming your growing operation to failure before you even start. The cramped quarters and controlled environment of a grow tent or room require forethought and planning in order to achieve great yields.

Inline fans help exchange stale air out of the system, often passing through several layers of filtration along the way. For example, carbon odor filters are often linked to ventilation setups in order to keep unwanted smells from spreading around the environment.

What Is CFM And How Do I Calculate It?

One important measurement you’ll see on all fans is CFM, or Cubic Feet per Minute. This number refers to – you guessed it – the cubic feet per minute of air that the inline fan you’re considering is capable of exchanging out of a given area.

For example, imagine you have an 8’ x 4’ x 12’ room. This is 384 cubic feet of space (4 x 4 x 8). Let’s now imagine you wanted to exchange all of the air inside that room with fresh air once per minute. You might think you need a fan rated at 384 CFM, but you’d be wrong.

It’s always a good idea to multiply the cubic feet of your available space by at least 1.33 to account for any airflow drop due to any filters, etc. that are attached to your ventilation system.

Using that 1.33x multiplier, we get a required CFM number of ~510 to exchange the air in our example grow room once per minute. There are other factors to consider when calculating your air flow, like:

Your Grow Lights

The type of grow light you use will have a heavy impact on your ventilation needs. HID lights (HPS, MH) run hotter than others (LEDs, CFLs) and thus will heat your grow tent or room faster, meaning it needs more ventilation.

If you’re growing with HID lighting, add a 5% boost to your calculations for every light you’re operating inside your grow room. If your HID lights aren’t air-cooled, then you should adjust by 10-20% as there’s nothing cooling your lights down at all, meaning your ventilation system has to carry more weight.

Carbon or CO2 Filters

If you’re attaching filters to your ventilation system, it’s important to account for them in your calculations. Add at least 20% to your CFM calculation if you have filters attached to your ducting.

Average Temperatures

If you’re growing in a room that runs hotter than average straight out of the gate, you may want to boost your CFM calculations by at least 25% to be sure you’re ventilating enough. If you have a double whammy of high temperatures and high humidity, boost this number by about 40%.

Length of Your Ducting

The length of your ducting can influence how much power it’ll take to pull air out of your grow room. On top of that, if you have any twists and turns in your ventilation setup, those will also increase the CFM needed to exchange air at the correct rate.

What Diameter Inline Duct Fan Should I Get?

An example of a Vivosun inline fan with ducting attached.

One factor that impacts your buying decision is the diameter of the fan. Wider fans will decrease the relative humidity of a grow room faster compared to smaller diameter ones.

Smaller diameter fans often have lower CFM ratings, but you’ll still need the right CFM for your space. After you’ve calculated your minimum CFM needs, select the smallest-diameter fan which can supply them. If you want to go a little higher than necessary, that’s fine, but remember that it might reduce your ambient humidity.

Other Factors To Consider

There are many other factors that will impact your buying decision when it comes to a fan. Here are some of the most common:

What is the Fan Being Used For?

There’s two basic uses for a fan: intake or exhaust. Intake is drawing air into the room, often through a carbon filter to remove pests or unwanted dust/pollen. Exhaust is venting air back out of the room.

Most setups rely more on exhaust vents than intake ones. That’s primarily because removing excess heat or humidity is far more common than needing to force air into a space. Our recommendations today focus on exhaust needs, although these fans can also be used for intake if desired.

Passive air intake handles the majority of growing needs. As you push air out of a room, more is being pulled in naturally through any crevices or gaps. Along with it comes any dust, pollen, or contaminants which might be suspended in the air.

Active intakes such as using a fan are usually an expense most growers don’t need unless they’re trying to prevent pests or pollution from impacting their plants. They can be useful, and they can be paired with added CO2, but it’s a fine-tuning of an issue which isn’t necessary for all but the most particular of growers.

Do You Need a Speed Adjuster?

Speed controllers can be nice, but they’re not universally required. If your fan is at your desired CFM range, you’ll never really need to adjust it.

If you’d prefer to get a higher-powered fan than you need for your space (perhaps to have room for future expansions), a speed controller can be a benefit. You can use the speed controller to reduce your fan’s CFM from its maximum level to the range of your current needs. Later, when you expand to match your fan’s capabilities, the speed controller won’t be as necessary.
