Our exhaust fans are a great option for cooling and providing fresh air inside a greenhouse, shop, or garage. They include a rustproof aluminum shutter frame with built-in interlocking louvers to reduce heat loss during cold months. These exhaust fans also come equipped with completely enclosed multi speed direct drive motors which can be set to multiple different speed with the attached pull chain. This allows you to reduce fan speed during cold months minimizing cold air shock to plants.

Totally enclosed outdoor rated UL507 certified motor
Rustproof aluminum shutter frame with built-in interlocking louvers to reduce heat loss
Multiple selectable speeds and on/off capability via attached pull chain
Prewired with a grounded 9' power cord (no wiring required)
Fans can be automated with any of our 110/120 volt greenhouse thermostats
Comes completely assembled
Made in the USA

I finally got a chance to install my 16" fan in my metal building. Instructions and installation was quite easy.The fan and louvers work perfectly and it really pulls some air.I have been wanting to do this for a while and am glad finally did it.I couldn't be happier with your fine product. Thanks!

Adding a second exhaust fan moved our greenhouse temperature to within one degree of the outside temperature.

It was easy to install and add on to the existing system we bought from ACF Greenhouses.

I have a 12x40 self built greenhouse and it gets REALLY hot. The fans were a VERY LATE after thought! LOL I will need to modify the greenhouse to accommodate the fans. This is MY design flaw...NOT the fans. (First time building anything like that). For now, I have placed one on the floor at the East end of the greenhouse sucking air in and the other one is elevated at the other end blowing air out. They knock the temperature down 20-30 degrees.
