I just don't like the noise they make is all I still have a few of them on the shelf. I switched to vortex fans they move more air then my old squirl cage fan is capible of.

Check at your local hydro store, they should have a mounting bracket that bolts over the air out vent. It should have a reducer with it to make the square hole into a round hole that a vent pipe can attach to.
Zandor Reviewed by Zandor on . Active Air Squirrel Fan Does anyone know how you would mount a squirrel fan in a grow closet? It's 180 cfm's. How loud do these things get? I've always used vortex inline fans in the past. Thanks in advance. :confused: Rating: 5
