These Galvanized blower wheels have many applications. Some applications are; fan coil units, room air conditioners, draft inducers, bath fans, ventilation, and heating and cooling applications. The bore can be adjusted by the uses of a bushing or can be bored to a larger size. A setscrew is used for fastening. The direction (cw: clockwise, CCW: Counter clock wise) is determined from the closed side of the wheel.
