Customer Reviews for VEVOR Shutter Exhaust Fan, 305 mm /12 inch with Temperature Humidity Controller, EC-motor, 904 CFM, Variable Speed Adjustable Wall Mount Attic Fan, Ventilation and Cooling for Greenhouses, Garages, Sheds

Vevor and I had a few issues at first but it was because I ordered incorrect, regardless there were a few further issues as far as technical suppirt but they did overall do very well in that department, too. The order itself was a very good product, the writers of the instructions may want to change them a bit to make them more understandable but I ended up figuring them out.

Got this little gem for our fixed greenhouse to use with the small solar system, it really does a great job. So far so good. I have had it installed for 2 weeks now and it is great. The controller is easy to setup, as long as you understand the High/Low function. I do not use the alarm feature no sense really. I would like to get another fan box without the controller, because this controller will supply signal to 2 EC motors. But the other fan box is not an EC motor. Still haven't found one I want to use yet.

Sopla super fuerte extra bastante lo recomiendo

Great product very powerful! =]

I feel like an idiot because I didn’t read the full description. This is a single phase 220 fan. It fits my application perfectly except for that. Not a huge deal but I had 120 there so now I have to run a new conduit over and bring 220 there. Oh well other than that it fits what I need perfectly.Finally hooked it up, turned it on and hot damn its loud!! Really loud. could be the application I used it for, to replace a dead fan from an ancient wall heater. but when I turn it on its so loud you can't even hold a conversation without nearly yelling. moves a lot of air though.

Larger than needed but works well. Filling in more words because this review needed 100 more words before could submit it apparently.

it is powerful fan
