Airflow quantifies the amount of air a fan delivers and is measured in CFM = cubic feet per minute. The higher the CFM, the more effective the fan, and the more air it moves. (See Charley's Tip PDF below for how to select fan and shutter size for your greenhouse.)

 Fan Size CFM HP Amps
12 inch Blade 760 CFM 1/30 0.9
16 inch Blade 1250 CFM 1/10 1.3
20 inch Blade 3000 CFM 1/3 3.8

Rough opening should be square and 5/8" larger than fan size.
