Dayton upblast ventilators are roof or wall mounted for discharging dirty air from industries and commercial kitchens. They are designed to operate continuously to vent grease, foul air and odour under low to moderate static pressure conditions. They have spun aluminium construction with a fully rolled windband for corrosion resistance, durability, stability, portability and withstanding a maximum inlet temperature of 300 degrees F. These ventilators come without assembled belt drive packages that offer flexibility in terms of rpm speeds, as the motor is not directly in contact with the fan's moving parts. Choose from a wide range of these ventilators, available in wheel diameters ranging from 11.25 to 36 inches.
