Belt Driven Exhaust Fans
Transfer out heat and dirty air with a belt driven exhaust fan. With belt drive fans, the belt is attached to the fan motor and the fan rotor shaft, as opposed to a direct drive exhaust fan wherein the motor is directly attached to the shaft. Belt driven fans operate more quietly and can be controlled more precisely by an operator than direct drive fans. Products vary by blade diameter, phase, CFM (cubic feet of air flow per minute), dimensions and other considerations.
