Depends on the exact fan but most exhaust units are designed to pull air. They can push but it's less efficient. It likes a certain amount of pressure behind it to get the air moving. Other fans may vary but almost everyone prefers to pull air through the cooltube.Getting my cooled hood delivered tomorrow quick question tho
Do I push the hot air out or pull though my fan? I'm guessing
Push it out but not to sure?
Cheers
I have cooltube - 6" ducting - flange in the ceiling - exhaust fan mounted in the flange - expelling into the attic
Keeps my closet temps ~5-6 above the intake room temp. And it's only a 240 cfm "booster" fan that I paid 25 bucks for.
