The Twister Exhaust Fan has been around unchanged for 20 years. If it works, why change it! This 20" Twister exhaust fan features a butterfly shutter which opens on startup and closes when the fan is off. This exhaust fan is perfect for ventilating garages, and other industrial and commercial spaces.
The motor is totally enclosed, maintenance free and has completely sealed ball bearings. The fan is fully assembled and the rear guard conforms to OSHA 1910.212 (a)(5) safety requirements. All you need to do to install it is cut your rough opening, attach to your building and wire it in. For specific installation instructions you may download them here.
The prop is made from aluminum and has a zinc plated hub to provide smooth, vibration-free operation. The 18 gauge galvanized butterfly shutter has an adjustable, positive draft-free closure. The housing is heavy duty 18 gauge.
