Used this fan to rebuild my whole house fan set up. In a nutshell, build it in to a piece of wood that sits inside the crawlspace opening to roof crawlspace area then crack a few windows in the house in the evening when temps start to cool off and it pulls cooler outside air in and cools house and forces super-heated roof crawlspace air out through roof vents cooling the entire house. It's a practical cooling method in temperate areas and way more energy efficient that AC. (i.e. cheaper $$)
Previous fan I used was a metal three blade design that came with a couple of the blades slightly bent. Tried re-balancing but it was never quite right so it had a fair amount of vibration and noise. Had to add dampers for the old fan to absorb some of the vibration / noise.
This fan is great, plastic molded blades mean no out of balance / significant vibration issues. This fan moves slightly less CFM than old fan 965 vs 1265, but also uses way less power - 45 watts versus 160 watts. 965 is plenty for my purposes. In this configuration I have to manually close the louvers when it's off since its designed for side mount install and uses gravity / light spring tension to open close normally, but this is no big deal.
I have an always on AC tap in point near the fan so I through on a timer as well. This setup would work just plugging in to the wall near the fan as well.

Not "Professional Grade", after mods, working OK so far for my purpose - light duty whole house fan.
Like a couple others I wanted a quiet, smallish shuttered fan to try to use as a whole house fan venting into attic. So this would be a horizontal install, not the intended vertical/wall one. To accomplish this (horizontal, exhaust-UP install) I:- fiddled with shutter spring to permit fan to reliably OPEN shutters.- used adhesive-backed insulation for windows along last edge of each shutter (kinda closing ~ 1/4" gap they each have).- carefully located where a screw could protrude into side such that shutters would NOT LOCK in OPEN position - screw protrudes from in one side to under last metal shutter where part of its metal bracing reaches when entering lock position. This so that when turned off shutters would reliably fall/CLOSE- installed pushon/pushoff switch with appropriate wire + heat-shrink tubing- cut screen to fit, using combo of strong dbl sided tape + duct take to secure around edges. Can't imagine using these without screens, there are gaps all over.As it looks like I should lube it every season (when replacing with insulated board), I'd have to pull the screen to do that. So will probably frame/box out something on exhaust side to support new screening there.Working well so far to exhaust 2nd floor air in smaller townhouse. Took waayy longer to put together & get reliable than I thought. But doesn't everything:)

The fan is very effective, and reasonably quiet It reduces the temperature considerably, at least by 20 degrees and keeps the garage decent temperature wise. It's not an industrial fan, but it seems well built. As mentioned in other reviews, the wire leads are a little on the low grade side. Even though it's only designed for 10 amp, (it uses much less than that), it would be good to have higher grade leads.
The next option was an industrial strength fan for $175+, so this works out great.

Gets job done and good value. Installed this in 2-car garage with half open storage area overhead to the gabled roof of one story stucco house. We're in Southern California so it gets quite warm during summer in the garage -- upper 90's to 100+. We only had a side door with a window and four exterior wall air vents, but nothing to create cross flow. I cut a hole in the stucco in the upper garage area on the opposite side of the garage from the door window and wall ventilation, and ran electrical to power the fan. See pics. I paired the fan up with Nutone RFTH95 Attic Ventilator thermostat, and a switch to turn the power completely off. I sanded and painted the exterior louvers to match the house.Reviewed in the United States on June 8, 2016

I bought this fan to exhaust cooking odors from the kitchen. I knew I wanted to install it in the wall between the kitchen and the garage, and the installation was relatively easy. I cut the drywall in the garage and then the corresponding wall in the kitchen. I also installed the Leviton RTF01-10Z IllumaTech 1.5A Quiet Step Rotary Fan Variable Speed Control switch. Once it was wired, I positioned the fan into the wall and secured it to the wall stud. The front of the fan looked Amazing! but the back of the fan looked unfinished and rough. I took a chance and ordered the Heng's JRP1118B Jensen Roof Vent Garnish and it was nearly the perfect trim for the exhaust side of the fan in the garage. Another feature that we will appreciate more in the future is the ease with which you can remove the fan blades and front trim for cleaning. We also use this fan as a small whole-house fan. This fan has exceeded our expectations!
