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)
