last year I built a 10x12x8 greenhouse, i put a regular fan in an opening i built at one end in the middle. at the other end i put a storm door with a screen on half the door. when the temperature climbed i had to open the window and turn on the fan, and not forget to turn it it off and close the window. which by the way my fan didnt really cool down my green house much. Now with my new automatic exhaust fan i set the temperature to what i want and let it do its thing and it really cools down the green house. thank you ACF GREEN HOUSES

Pleased with the fan and good service.

The exhaust fan kit was easy to install on my greenhouse and works great. It made more sense to go this route than to buy four separate vent openers that would only provide natural drafting.

ACF offers great solutions for my hobby and excellent service. Whenever I have questions, they respond promptly to my emails and from what I have seen have the best pricing on products and shipping rates.

Installed the fan and louvers as instructed, works well to cool down the greenhouse. So far so good.

Excellent product, fan, vent & thermostat kit, for a small greenhouse!
