This review is from: Vortex Powerfans 6" In-line Fan
I had trouble keeping my 10' x 12' greenhouse cool until I installed this fan. Built like a tank. But don't expect it to be quiet. Hooked it up to a thermostat and a speed control unit. I pull the outside air through 20' of buried pipe to pre-cool it underground. Make sure you put a screen over the outlet so it doesn't eat fingers.

This is one blowing machine, but, don't try and put a speed controller on this fan. A little while after I put a speed controller on, the fan stopped working!
