Essential Info

With this duct fan installed into your home or business building, you’ll be able to boost the ventilation into or out of a certain area. Move warm or cool air into rooms that are notoriously hard to keep at a comfortable temperature. Install into a bathroom to draw out steam while hot water is running. Or use it in workshops as a fume control system. The fan is designed to serve individual rooms for more precise climate control and ventilation. Steel housing and an aluminum fan make the fan ultra-durable but allows for operation so quiet you’ll forget it is running.

This product is also available in 8, 10, 12, and 14 inches, each sold separately. There are also 6 inch and 8 inch versions with automatic switches to turn on the booster fan whenever the heater or AC come on.

    Works great.
    EDWARD -- perkasie, PA   12/31/2012
    Ordered 2 had to wait for 1 unit (out of stock) They move more air than my old duct boosters. still have fan noise - I only have 18 inch run from fan to outlet, but can feel more air out of register in floor.
    EDWARD -- perkasie, PA   12/27/2012
    this booster is easy to install and moves a great amount of air. It is noisy in my short duct run with the air noise because of the amount of air being pushed. But the amount of air is what I need
