Product Details

Fan is designed for commercial and industrial applications that require high volumes of air at low to medium static pressures. Built with 6-blade heavy-duty cast-aluminum propellers, heavy-duty drive-frame channels, bearing plate, and motor plate. The variable pitch, adjustable motor pulley optimizes fan performance. Air handling-quality bearings meet a minimum of L10-100,000 hr. Mount fan vertically for exhaust operation; horizontally for supply. Appropriate motor, belt, and sheaves must be purchased separately to obtain performance listed.
Note: OSHA complying guards are required when a fan is installed within 8 ft. of floor, working level, or within reach of personnel. Review OSHA codes and UL standards.
