Dayton belt-drive exhaust fans are designed for industrial and commercial exhaust applications. These fans have 5-blade reinforced steel / aluminium propellers for moving large volumes of air at low static pressures. They further come with open drip-proof (ODP) motor enclosures that permit outside air to pass through the windings for proper ventilation. These units also include a drive package that consists of a motor, belt, bushings, and sheaves (packed separately) to customise the assembly as per requirement. They can be mounted in vertical or horizontal positions and are available in 20 and 60 inch blade diameters.
