Quiet Portable Air Conditioner

180 CFM Squirrel Cage Exhaust Fan. Exhaust fans are the most efficient way to combat both C02 loss and high temperatures, two things that can hinder your plants. They are set up to either blow air to another room or down a long tube to the outdoors. How do you know what size you need? Calculate the CFM (Cubic Feet per Minute) by dividing the cubic footage in your grow room by five. The blower you will choose based on this will be large enough to replace all of the air in the room in five minutes.
