Duct Fan Size
It is without a doubt that size usually plays a role in the operation of the product, nonetheless just in terms of the amount of atmosphere you want in your room and it also relies on the size of the place. For instance, a grow tent with the size 10×10 can require a duct fan higher power than a closet with the size 2×2. First thing first, you need to know your space before choosing the size of the duct fan you want to use.
After that, it is essential that you measure the space that you will place your fan. Every space in the room is to be measured since you may waste your money buying an expensive fan that does not fit your space or your needs.
Furthermore, by measuring your space. you can decide how you place the fan, whether you hang it outside your space, inside or attach the duct fan to the floor or ceiling. So visualise the space before purchasing does mean a lot and help you decide which size best fits your place.
There are in fact a lot of sizes of duct fans, from 4” to 18”. Such a number of sizes does sometimes confuse buyers.
Some consumers pick big size fans as their room is relatively large and needs to be ventilated, whereas some may choose small size since their space is small and a large size fan is not necessary for the space.
Power Level
Another thing that you want to take into consideration before buying a duct fan for the space is the power rating of that fan. This is usually measured in cubic feet per minute, in short CFM. Different spaces require different CFM, so you want to know what is the CFM requirement of your room in order to choose the quietest duct fan that suits your place best.
Our team can guide you on how to decide the power requirement of the product is needed in your place by measuring the height, the width, and length of your space.
After you have measured all the needed dimensions we have mentioned, multiply such three dimensions to measure the volume of your room. Many people have found that 3 minute is the ideal time your duct fan should take to pull entirely the stagnant air in your space out. So, divide the volume by 3 and you will know the CFM that your room needs.
The CFM requirement of your space will increase if you add other devices or things into your duct fan, for instance ducting, the carbon filters, and heat. So it is necessary that you consider this to know precisely your CFM requirement and choose the right duct fan. It is very important to know your CFM requirements in advance when you buy a fan as it is a waste of money and time if you find the fan has no sufficient power to take out all the hot air or maybe too large that it is not necessary.
Noise Level

Heat From Lighting
So, does a high heated grow room make you physically unwell or uncomfortable in your room? Then, a duct fan can solve the problem since it is able to exhaust this tamed air from your space. In addition, they will replace heat with the air from outside, making your room more ventilated.
The lighting of your space will play a role in determining the power level that your duct fan requires.
Inline fans reduce the heat of your grow spaces by taking in air from outside your space and releasing the heat out of the space through ducting that’s connected to lights.
The ducting particle is directed outside the room, or to other places. Your duct fan will push or pull the stagnant air out of the room so that it can maintain the temperature of the space at an appropriate level.
Humidity

The flow of clean air that moves through your grow room can notably decrease the humidity, thereby reducing the possibility of a serious plant disease that can completely destroy your plants.
Carbon Filters
If you are finding a thing that will scrub the smell of your grow room, you might want to take the carbon filter into account,
Carbon filters are able to scrub the smell, and there are a number of sizes depending on the size of your room.
Duct fans operate in cooperation with those carbon filters since they are attached to them. In most grow rooms, a carbon filter is connected to a duct fan so that they can work at maximum efficiency.
The reason for this is that a carbon filter requires a duct fan to exchange the air out the particles of it and keep it ventilated.

That is the reason you want to have a duct fan as it is crucial to make your space ventilated.
Do You Need a Speed Adjuster?
Speed controllers are nice, but they’re not necessarily a must. In case your fan is already in the CFM you need, it is likely that you will not have to use it at all.
If you want to have a fan that has a higher power than your space requires for your space because you want to expand it in the future, a speed controller is a brilliant choice since you can adjust the speed of the fan due to your want.
