Dayton Upblast Ventilator, Spun Aluminum, Wheel Dia. 11", Shaft Dia. Wheel End 3/4"

The Upblast Ventilator is designed for use in restaurants, schools, and commercial and industrial applications to exhaust contaminated air from kitchen range hoods up and away from the roof. Its 1-pc. rolled aluminum windband is fully welded to the base to create a virtually leakproof seal between the ventilator and the mounting surface. The internal steel support braces and fully rolled windband also increase the rigidity of the ventilator for greater stability during transport and installation.

The motor, drive frame, and wheel are isolated from the mounting base by independent neoprene studs—preventing metal-to-metal contact and greatly reducing overall noise. The motor compartment is also isolated from the contaminated air stream and is cooled by outside air pulled in through an oversized breather tube by the spinning action of the wheel. Motors, sheaves, and belts are packed separately when unassembled ventilator with drive package is ordered.
