iPower 12 Inch Wall Mounted Shutter Exhaust Fan with Temperature Controller and Power Cord Kit, Aluminum, 1600 RPM, 940 CFM, for Attic, Garage, Louvered Vent, Plant, Greenhouse, Silver

Installed exhaust fan in a polygreen house, (10x20x7.5’), keeps temperature at or below 92, even on bright sunny days, (outside temperatures in 80,s in early May in Michigan. So far has kept about a 10 to 12 degree temperature differential inside the greenhouse compared to outside. This with the large door zipped shut- using only the side screen vents and exhaust fan. Temperature control is sensitive no more that a few degrees swing up in temperature, before starts exhausting air. . Install was easy, common sense, wiring was easy also. Fan also creates air movement over plants from pulling in air through side vents. My size fan is the 20” model. Moves a lot of air. Con: The 1/2 “ conduit connector for supplied electric box missing- needed to secure your power supply line to box. Easy purchase at any hardware store. The suppled power plug lead is short- you will need to extend your power supply line to within a couple of feet of fan - so you can plug in. Also, thermostat control suppled wiring is very short- allows placement only within inches of left, rear of fan grille. However, the thermostat is separate from fan with own wire leads-so if desired you can extend wiring and place were best suits your needs. As said above, Wiring leads supplied for power plug- same- short.

This fan replaced an ancient one that was running on a timer , which was burning juice 24 hours a day. The fit was perfect. Everything went very well. Love the thermostat control. Big Thanks

The product seems to be built very well and it runs very smoothly and powerfully. I bought the fan with temp control. The instructions don't appear to cover the additional wiring for the temp control. I simply wired all black together (not advising folks to do that). The challenge was mainly the wiring coming out of the motor was too short. It was hard to work with and pull into the box. The stretch from the fan itself to the box eats up most of the line.I think another 4-6 inches would be ideal. Better to cut back what you dont need than need more wire. Aside from that, I definitely recommend the product.

Great fan, great product. Super easy to install. I have 16 foot side walls in my metal garage and with this fan mounted up high it sucks out the upper hot air fast. I have the thermostat control, just set it and let it do it's thing. Customer service is also top notch, couldn't ask for better.

This fan was easy to install, and functions as advertised. The design made installation easy with a large mounting edge. The temperature control works great, and the fan is powerful enough to quickly cool our 128 sq ft greenhouse. It has dropped the temperature by over 20 degrees. Make sure to secure all sides of the fan or it will vibrate. The louvers work as they should. The main power cord is too short, and you will need to extend the cord length so you can attach the temperature control box to a stud. Also, it only comes with one cord strain relief, so you will need a second one of those.

the fan is surprisingly quiet. the thermostat control box really is meant to be mounted with the screws on the right side of the box. the mechanical parts inside are shifted to them left and the wire is meant to enter the box on the right so that it isn’t in the way of the mechanical parts moving. i went the other way and had to zip tie my wires out of the way. the wire lead from the fan is really short so i replaced it with a longer wire. if i hadn’t had to get inside the fan wiring, i’d have given 5 stars for ease of installation. the temperature you set is for shutting the fan off, and if the temp goes more than a few degrees higher than that, it’ll kick on by itself. i would definitely recommend this product to someone looking for a good exhaust fan that you can leave alone after install and let it do its work.

I won’t give it 1 star because the fan might work great, but the thermostat is not manufactured correctly. I read another review showing the wiring diagram and actual wiring inside the thermostat didn’t match and asking if the fuse was bypassed. The fuse is bypassed in the thermostat he showed as well as the one I received. I checked the functionality of the thermostat with a multimeter as well as examined the parts closely. There must be a bad batch of these as I watched a video demonstration of someone using a heat gun to make it work, and the wiring inside the thermostat did match the wiring diagram (see the third photo). The wiring diagram is how it should be inside the thermostat, otherwise the fuse is useless. The thermostat will still work, but the fuse blowing will not stop the power from continuing through the thermostat. Someone said contacting the seller went nowhere l, but I will try anyway and update here later.

Great exhaust fan. Installed it high up in my garage and it does a great job if sucking out the heat sitting up there along with smoke and fumes. I only turn it on when needed. I did install a rheostat to control the speed, lower it a bit in winter so it doesn't suck out all the heat, but it buzzes quite a bit when not running full speed. Other than that it moves a lot of air and I'd definitely recommend.

Great fan, powerful, teamed up with the thermostat gives it the perfect combination for my generator enclosure, highly recommended, Fair price as well.

Ease of install, comes with a programmable thermostat that works perfect, not noisy, looks good.

Used in greenhouse for entire 2023 hot summer. Really nice to have automatic start and stop by thermostat control.

Kept a room13 x 13 free of moisture from a hot tub 8x8..excellent !@

You have to have one at this cost there is no thinking about it so easy to install
