In-line, 10" fan capable of moving 588 cubic feet per minute through 10" diameter ducting. Think about it! You want to move a bunch of air from point A to point B like from the inside of a garage through a duct to the outside of the garage or the air from an air handler into a remote room. That's almost 600 cubic feet of air per minute (although it will be less than that when you add the ducting, grille, hood, etc. - maybe 450. But that's still a lot of air.) Put it on a thermostat switch or a pressure switch and it will come on and go off automatically. Put that in your duct!
