How long are you willing to
wait?
Divide the
cubic feet of the typical structure you ventilate by the CFM
rating of your fan or the one you might purchase. Our
4-HP fan
will completely replace the air in a 2000 square foot house in
less than 1 minute! (See calculations at right.) Our
6.5 hp fan
will do it in 33 seconds!

Example: 2000 square foot house with 8-foot ceilings =
16,000 cubic feet.
A
20GX120 VENTRY Fan pushes 16,500 CFM.
16,000 CF/16,500 CFM = .97 minutes, so our smallest fan
would completely ventilate this house in less than 1
minute!
