iPower 20 Inch Wall Mounted Shutter Exhaust Fan with Temperature Controller and Power Cord Kit, Aluminum, 1200 RPM, 3368 CFM, for Attic, Garage, Louvered Vent, Plant, Greenhouse, Silver

Keeps my shipping container cool and since it's 30+ feet away, noise isn't a problem.UPDATE:!0July 2023 I awoke and turned it on, about 10 minutes later I heard it stop running. Immediately got online and initiated replacement process. One is on the way, should be here by Saturday.I am a wheelchair user and live off-grid in the desert. Town is 70 miles away.. so I had to wait until yesterday to get someone to take it down for me. I checked it out and nothing is wrong with it visibly. Glad I did not wait to get another sent. Been over 110F here for the better part of 4 weeks.I am expected to return the old one by Monday(7 days) or be charged for the replacement. I have to wait for the new one to get here so I can use it's box to send it back. UPS stopped by yesterday to pick it up and had the sticker to ship it back at their cost. I hope it gets here tomorrow so I CAN send it back before Monday and not have it charged to my bank account...there is NOT enough to cover it, it would be the first time in my almost 60 years for being overdrawn. THAT would make me angry. I will update when the replacement arrives.Note that I am WELL PLEASED with it's performance/cost. That is why I asked to replace it instead of a refund. It is a well built fan, I am assuming it's a one-off anomaly that caused it to fail.Update 13 July 2023 It was delivered yesterday, got it installed today and it is rnning fine. Used the box it came in to box it up fo the return. Hoping to get ups to come by or I will have to drive 140 miles round trip into town to get it to ups for return.Awesome service by this company. BUT the price is already increased to 68 dollars today, 59 yesterday when I bought it it was 58 and change.25July2023 Update:12in Ehaust Fan working great still. Pretty much on around the clock since it is summer in the desert. Notified by Amazon today, that they received the faulty fan that I returned. Had to drive 140miles round trip to do that. UPS came the next day after I set up a return and replacement fan, as they were supposed to do. HOWEVER, since it is 70+ miles to the nearest town and I needed the box the replacement was going to arrive in, to ship it back, no could do. Called ups to arrange pick up when I had it ready, was going to be 25 smackers. So, I loaded up the truck and went to Beverly......Hills that is, swimmin' p00ls, movie stars.I still highly recommend this 12 inch exhaust fan. It moves a LOYT of air, fast. makes my 100+ F container, bearable. So much so, that I did not and ain't gonna install my air conditioner this year. WEEEE doggies!

The media could not be loaded. 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.

We installed this in a small enclosed back porch where the litter box was targeted to go. Easy installation and works like a charm. The only little surprise was that the “corded” fan had no plug so I guess it was wanting to be directly wired to a switch. We added a grounded rubber 3 prong plug to the wire and plugged it into the outlet. Presto. Amazing results. It drew out the air rapidly and effectively. Will add a grounded outlet with switch so that the unit can be turned on/off without unplugging. Another little issue is that upon turning off the fan, the exterior vent slats don’t drop flush. They kind of stay at half mast so we have to remember to smooth them down to prevent mosquitos from coming in. .

Works great
