As part of a ventilation system for HVAC equipment, a belt driven fan releases low pressure circulation. A belt drive exhaust fan operates as the belt connects the motor to the rotational parts of the fan. This type of exhaust fan retains excellent RPM speeds and is ideal to install within warehouses, large garages, and other interior open areas. If viewing other fan options? See our direct drive exhaust fans that use a shaft or axial instead of a belt. Additionally, we carry an assortment of bathroom fans and range hoods.
