iPower 7 Inch Wall Mounted Shutter Exhaust Fan, Aluminum, 1600 RPM, 760 CFM, for Attic, Garage, Louvered Vent, Plant, Greenhouse, Silver

Has held up well. Been 8-9 months and have not had any issues. Set up in my chicken coop and does a nice job.

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.

I bought the 7 inch size and overall I am satisfied. It is quiet and moves about as much air as you can expect any 7 inch fan to do. Nowhere near their rating, maybe about 200 CFM. I say that because I have another 7 inch similar fan that is rated about 200 CFM and they seem about equal in flow.The first disappointment is that it does not come with a cord so it's definitely not plug and play. Fortunately I had one so I got it up and running.More serious in the long run is that the shutters do not close against any edge on the sides. This leaves about a quarter inch on each side of the shutters where bugs can get in when the fan is off. I think I can add foam strips but access won't be easy.It comes with a ridiculous blue film on the shutters which others have said are almost impossible to remove. Don't think I will even try.Outside of that it appears to be a quality built fan that runs smoothly and quietly.

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.

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!
