WHISPAIR™ blowers reduce noise and power loss by utilizing an exclusive wraparound plenum and proprietary WHISPAIR™ jet to control pressure equalization feeding back flow in the direction of impeller movement, thereby aiding rotation. The headplates, gear cover, drive end cover and rigid, one-piece casing are grey iron. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts, secured with a locknut.
