No sorry, let me clarify! I had a 600 CFM fan hooked to a carbon filter pulling air out of sealed room. I put another exhaust "hole" in the bottom of the room. So as the exhaust fan pushed heat out it would create a vacuum pulling cool air in. I still had temperature problems as well as humidity. I bought an additional 600CFM and hooked it up to the "hole" I was using to pull air from outside of the room. Now they circulate air at the same rate
Oh right
