VEVOR 16'' Shutter Exhaust Fan, Temperature and Humidity Controls, 18.9 x 18.9 inch, 2650 CFM, ETL Listed, 120V/60Hz, 70W, Black

This system is pretty good. Takes a bit to figure out the alarms and how to set them. Air flow seems sufficient and I got it almost half price on sale, so it was a great deal. Temp sensor seems to be accurate

Easy install, the screen is clear, easy to set temperature and humidity limits, moves a lot of air in the greenhouse, sensor very accurate, correlates with my thermometer and humidity device perfectly

I bought this fan for my greenhouse. Easy to install and seemed to be good quality but after a month of using it stopped working. The motor isn’t locked but the digital display won’t power on. I checked the power with a meter and it shows the correct voltage.

Easy mount, good options, electronic controls - I also like that Vevor provides some good expanding concrete / brick mounting options, but would have liked to see a few bolts and nuts included as well. I was adding to a barn with 3/4" plywood sides so the (probably more expensive) concrete mounting bolts when in my supplies box and I went out to buy four 1 1/2" bolts and nuts instead.Installation is really easy, just cut a hold with the correct size, hold the fan frame in place and add bolt, plug in power, set the electronic control panel and you're ready to go. Options for turning on at certain times or based on temperatures and humidity above or below specified ranges are nice, but all I care about is auto on when temps go above what I set it to. Quiet, powerful, effective.I liked it enough I bought a second for a different barn, from amazon, or Vevor direct with free shipping, same price, and possible discount coupons as well. My second fan arrived even faster direct from Vevor than if I had ordered via amazon Vevor which showed a few delays

Measure size needed first

I stumbled across the Vevor website and was worried it was not legit. I looked up product reviews, investigated the website's origins and read about the complaints with the Better Business Bureau. I decided it wasn't worth the risk. I later found the same brand on Amazon and felt safer because of the Amazon policies and for the first time I bought a protection plan in case it was a lemon.It's a great quality, though it arrived with the fan upside down in the frame. The temp/humidity controller works great. It's easier to program than the Inkbird controller I already owned, but I would have liked a wifi connection with an app to control it remotely and monitor the temp/humidity in an app, like the Inkbird. The controller it comes with also regulates speed. it's not always on full blast and it's low noise in general. Very happy with it so far.I have more trust in the brand, but after reading their standard return policy on their website, I'm staying with making purchases through Amazon to be safe.

great fan

Great exhaust fan. Works great in my greenhouse
