This Airmaster 42735 belt drive exhaust fan has a 36" blade diameter, a venturi housing, and is suitable for ventilating a building to the outside. It has a 1-speed, 230/460V, three phase, 1-1/2 hp, permanently lubricated, totally enclosed ball bearing motor. The blade assembly (consisting of a pulley, steel hub, and spider) holds the fan head's four aluminum paddles, and a belt between the motor and fan pulley drives the fan. The epoxy-coated steel venturi housing allows the fan to be installed without external framing, and self-closing shutters (not included) can protect the fan from rain and snow when not in operation. The motor of the belt drive exhaust fan is out of the air flow path, making it suitable for use in the presence of dust or other airborne debris. This belt drive exhaust fan is Underwriters Laboratories (UL) Listed for quality assurance and is suitable for use in building ventilation, such as for a warehouse.

Industrial fans are used in workplace environments to exhaust fumes or direct air flow. Most industrial fans have coated metal parts and lubricated motors that are permanently sealed to help protect against environmental hazards, such as dirt and airborne debris or corrosive fumes. They can have fan blade cages that meet workplace safety standards, as well as a variety of mounting mechanisms for precise placement to direct large volumes of air flow. Electronic circuitry for industrial fans matches the power specifications found in the workplace and provides the initial torque needed to start up a large blade fan. Industrial fans are used in warehouses, gyms, and other commercial environments to ventilate spaces and to circulate air.
Airmaster Fan manufactures circulation and ventilation fans for industrial and residential applications. The company, founded in 1886, is headquartered in Jackson, MI.
