Dayton® medium-duty belt-drive 54" exhaust fan is designed to be used in commercial and industrial applications that require high volumes of air at low static pressures. The fan features a 5-blade reinforced galvanized-steel propeller, heavy-duty drive-frame rails, and a 1-pc. motor/bearing plate. Variable pitch and an adjustable motor pulley optimize fan performance. Heavy-duty cast pillow block bearings are regreasable. Mount vertically for exhaust operation; horizontally for supply.
Drive package (which includes the appropriate motor, belt, bushings and sheaves to obtain the rated performance) must be ordered separately.
• Air handling-quality bearings meet a minimum of L10-100,000 hr.
• UL and C-UL Listed
• Unassembled

Note: OSHA complying guards are required when a fan is installed within 8 ft. of floor, working level, or within reach of personnel; order No. 1WBU8. Review OSHA codes and UL standards.
