Master Flow® whole house fans are smart energy savers and an important part of a complete home ventilation system, particularly in climates where cooling costs are a concern. These fans efficiently help beat the heat by forcing hot air out of your home while simultaneously drawing in cooler outside air. For convenient operation, the fan is controlled by a two-speed pull chain switch.
