Customer Reviews for VEVOR 12 inch Shutter Exhaust Fan, Wall Mounted Attic Vent Fan with Smart Programming Variable Speed Temperature Control, 1500 CFM,EC Motor,Timer, for Shed,Garage,Greenhouse Ventilation Cooling,Black

so far it was easy installation and the wiring needs a receptacle to plug in and I just used a extension cord. it is very quiet and my shed went from 101 to 97 pretty quick. I bought a 12x12 louvre vent to draw air into my shed and I can feel the suction.

Installed it in my greenhouse. Works great. Very quiet.

I put this in my shed to keep my battery temps down a bit and was surprised to see a 10-15+*F drop just by circulating air through there. I do have some poor man insulation throughout the shed so I am sure that helps but the fan is doing the work and making the biggest difference. Way better than just the normal vents without a fan. On my solar battery it uses 20 watts and I have set to kick on only at 83F. Seems more sensitive than another temp control panel. Not sure which is more accurate. Note the auto on function beside to set the other auto functions way outside a reasonable limit so the fan isn’t triggered based on something else than what you set it for but it is useful if you wanted it to kick on for 4 different modes it will H/L temp H/L humidity. I only use high temp

Seams to work just fine. Hope it last a long time.

I bought this for my attic and it runs but I cannot program the unit to shut off in the Auto Mode. I've tried several time to program it but it will not shut off.

Very easy to setup and it keeps my greenhouse the right temperature and humidity.

Je suis bien contente
