Customer Reviews for VEVOR Shutter Exhaust Fan, 406 mm /16inch with Temperature Humidity Controller, EC-motor, 1747 CFM, Variable Speed Adjustable Wall Mount Attic Fan, Ventilation and Cooling for Greenhouses, Garages, Sheds

The only draw back for this item is make sure you measure. I selected the 14 inch thinking I’d still have a couple inches of space between joists. It was a very tight fit. I did have to bend some of the fan screen. Easy to operate.

Works very well in my attic. You set it and forget it. It does it all on its own. Very satisfied.

You need to press the UP and DOWN buttons simultaneously for about “5 seconds” to toggle a trigger on or off. This is not specified in the User’s Manual. It took a few emails to Vevor product support team, who are very responsive, to learn this. I love the fan now that I know how to use it.

This fan blows all the competition out of the water (pun intended). The control is a mini computer that controls fan speed, hi or low temperature or high or low humidity. It also has alarms. The digital temperature readout is big enough to see from a distance. I paid more for a simple thermostat controller than I did for this fan. I hope it lasts. The instructions were readable and once understood the controller is fantastic. A very nice greenhouse fan. We only run it at half speed for our 8 x 12 greenhouse.

Little louder than expected when on top speed. But other then that it is a great by for my attic on my house.
