Works exactly as needed! The instructions are a little difficult to follow. The fan turns on at a certain temperature and/or humidity. Couldn’t use the louvres due to the current design of the fan, but works really well!

Works good for pulling heat out of a pole barn. The only thing I don’t like is sometimes when it shut off at the temperature it’s set at it continues to run slowly and you have to cycle power to it to reset it.

Excellent quality, well made very impressed! Fast Shipping!!

One strong fan! This fan is everything that it was described to be and extremely quiet. Love it so much I plan to buy more for other projects.

Works wonderful, easy to use and set up.

This fan works great. I set the temp and humidity I wanted it to come on for. Moves a lot of air but relatively quiet.

It comes bare wire, you'll need a plug end or terminal box. Moves enough air to keep the upper story from heating up where it used to be consistently hotter than outdoors, sometimes now I need to shut the other fan off to be comfortable when the night or morning air is too cool. I plugged it in to a drop light extension cord for now, with a plan to add thermostatic control and hardwire it.

The fan was very easy to install. I used the front packing cardboard as a template, and powered the unit through an outlet with a thermostatic switch plugged into it.

Using it in my greenhouse with automatic temperature control and the results have been just great.

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