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

Fan is quiet and the louvers work well. You can see how far the louvers extend with the fan speed. I've been meaning to contact Vevor, concerning the operation of the controller. I want to have it come on when the humidity reaches 60%. I just can't figure it out.

Fan works, okay. Wish It had a little more power. I had to install a inlet. That helped some not sure what I'm going to do during the winter time. When I have to close the inlet. Overall, it's working.I'm glad I bought it

Product seems to be well made, I just wish it was not digital and a bit tricky for me to figure out how to set the fan to come on at the right temperature for me. I even had some help setting it, but it is not set right. I will call the number for help when I can get some time to.

This is a really nice unit for the money. has been working not stop since we put in. we are in a very humid area and with the settings its great.

As long as you have the right tools it’s not too hard. Reasonably priced and has been running a lot in this humidity. 2 months old and no problems.

Everything works great! Only reason it wasn’t a five star review is the cage was bent from shipping (not fault of VEVOR) I was able to straighten it out and install with out issue.

This is a well-built exhaust fan. I am using it on my Generator shed with no issues. Only feedback will be to add a bug screen as the fins do not cover all and will allow for bugs to enter the shed. Had to make my Own bug screen, and it is working perfectly.

Delivered on time worked when plugged in very simple set up has been working for 3 weeks no problems

Perfect, just what I needed, works well.

Quality and installation is easy. Wiring also easy. Understand how to turn it on and such just having problems in my greenhouse setting it to turn on at certain temps and turn off and stay off at certain temps. Wrote in and asked, was just told how to set up, but when I did it kept shutting off until it got below the low temp and turning back on.. watched a YouTube video and still had some issues but at least I can manually turn them on and they work great!
