This exhaust ventilator is designed to meet the general clean air exhaust requirements for industrial and commercial buildings. The rugged and reliable construction makes the fan capable of withstanding severe exhaust conditions. The spun aluminum construction features a fully rolled windband bead for increased stability and easy transport. Fresh outside air is drawn in under the motor cover to maximize motor life. The drive frame is internally isolated from the rest of the unit through the use of neoprene isolators, for long life and quiet operation; there's no steel-to-steel contact.
