Imperial Ventilation Fans will quickly ventilate your grow space, bring the temperature and humidity down, and push or pull odors and other pollutants through your air filters.

Withstanding the test of time, centrifugal fan is one of the most popular applications for both industrial and hydroponic industries. This design has less performance drop when restricted by a carbon filter, allowing the robust design to work effortlessly to ensure maximum airflow and reliability.

This design allows the reduction of noise and vibration which features a backward curved propeller design that creates a very powerful airflow Along with a permanently lubricated bearing that requires zero maintenance, this fan is designed to be a workhorse for any air delivery needs.

In an exhaust system the air only passes through the filter once which makes it even more important that as much odor/VOC ( Volatile Organic Compounds ) is removed as possible with the one hit. This means that the VOC must have a particular amount of time of exposure with the carbon in order to be fully adsorbed. The benefit of running an exhaust only system is to create a negative static pressure within the room which will draw fresh air into the room.

Typically for exhaust we recommend a simple length x width x height /3 calculation. This will give you the amount of air (cubic feet per minute, CFM) that you will need to move to properly ventilate your space allowing for a three-minute air exchange (all the air in the space is exchanged for fresh air every three minutes). This is the number you will match your filter to.

Example:

Room size: 10’x12’x8’ (960 cubic feet)

960 cubic feet / 3 minutes = 320CFM (Minimum recommended CFM to exchange the air every 3 minutes)

CUSTOMER REVIEWS

Don't just take our word for it - here's what our customers have to say.

mint service

awesome product and fast delivery. 150mm is a little over kill for a 2'x4' but with a pod filter on the intake and a rag over the outlet along with home built insulated fan box,insulated ducting and home built silencer, paired with the inkbird controller this unit is perfect and now wisper quite.
now to decide on cmh, de hps or led 🤔

Moves Air

Great extraction at a good price point. A bit louder than my other but not filtered, speed control a little solved it though

Pumps like a boss

Thanks heaps

It works

Does the job, yet to slap a carbon filter on it, but so far so good. speed controller is good, will work on any fan (I think) because it plugs in to the fan's power plug and controlls speed by controlling power supplied to fan. This may also be the reason why at low speeds there seems to be a hum

works very well

impressed with this product definitely recommend the speed control or would be to powerful on full for smaller areas makes a lil more humming sound when set to low speed but overall well recommend
