Dayton medium-duty exhaust fans are designed for proper ventilation in warehouses, factories, manufacturing plants and offices. These units feature 5-blade, galvanised steel propellers to move large air volumes at low static pressures (0.125 inches or less), thereby reducing sound levels while operating. These fans also feature totally enclosed nonventilated enclosures (w/o openings or external fans) and utilise a simple convection method for heat dissipation from the motor frame. They have belt-driven design that allows flexibility in fan speeds to optimise fan's performance. The complete assembly includes the motor, belt, bushings and sheaves (packed separately) and can be easily mounted in either horizontal or vertical position. Choose from an extensive range of these exhaust fans, available in fan speeds ranging from 861 to 1241 rpm.
