The WindMaker fan packs a lot of air into a small package. Built for hydroponic grow rooms, the high output motor includes permanently lubricated bearings for quiet, energy-efficient operation. The speed of the all-metal fan blade is controlled by a reliable 3-speed rotary selector. As protection from the harsh grow room environment, the fans’ grill, stand, and blades are given a black powder-coat finish that is both chip-resistant and easy to clean.
