    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

    • Fans can be automated with any of our 110/120 volt greenhouse thermostats
    • Comes completely assembled
    • Made in the USA

    Happy Customer

    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.

    Great power and quiet

    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.

    Fan

    This fan cools down a 10x12x10 greenhouse in south Texas heat. Highly recommend

    My new go-to

    Informative people, fast service and shipping. And the products are top quality.

    Great Fan

    My husband is very impressed with this item. The intake/outtake? is more powerful than our last. And it has cooled down my greenhouse. Very impressed!

    Fan is marvelous!

    Perfect application for my little greenhouse!

    Multi Speed Exhaust Fan

    The exhaust fan was exactly as described. It runs quietly with no vibration and decent output. The 4 stars was given because the louver door has a gap when closed. This is large enough for insects to enter.

    surestat-t116-plug-in-portable-thermostat-control.

    This was easy to install and works perfectly...my fan starts when the greenhouse reaches the time set. Highly recommend .

    Vent fan

    Have this same fan that has been performing perfectly for the last 3-4 years. Bought this one as a backup, in case of problem with existing fan. Old fan is still running great. Very happy with unit.
