VEVOR Shutter Exhaust Fan, 16'' with Temperature Humidity Controller, EC-motor, 2650 CFM, 10-Speed Adjustable Wall Mount Attic Fan, Ventilation and Cooling for Greenhouses, Garages, Sheds, ETL Listed. Is a good product. Works as it should.
I bought this for my motorcycle shop to help with the heat of Florida summers. I used it where all the hot air gathers and makes my air conditioners not work very well. Since I installed this my air conditioners kick butt, this sucks all the motorcycle exhaust out when needed, and does a great job at moving air. For such a small fan it moves and immense amount of air. It is very quiet and the controller makes it very very easy to use and it's just a must-have for any kind of Automotive or motorcycle shop.
Installed in my 26x26 garage. Saw inside temperature drop the next day, after having fan run all night. Set up temp. guage and it works as it should. Fan is easy to install and secure to wall.
Assembled fan is of excellent quality and a bargain for the price.
I installed this in the storage area of a beach house to keep the humidity in check. I got the 16" due to the 16" OC studs. However, the fan is not made to install between 2 US-standard studs. Thankfully mine weren't structural, so I just cut the one and reframed around the fan. Once it was installed, it worked well for my purpose and setting the control board to the right setting for me was fairly easy. Even at the highest fan setting, it was still relatively quiet for where I had it installed.
