Roots RCS-J Whispair Rotary Blower Frame Size 821-J available in stock!
The RCS-J Whispair Rotary Blowers Frame Size 821-J is a heavy-duty unit designed with integral-shaft ductile iron impellers having an involute profile. Whispair blowers reduce noise and power loss by utilizing an exclusive wrap-around plenum and proprietary whispair jet to control pressure equalization – feeding backflow in the direction of impeller movement, thereby aiding rotation.
Basic blower description: The head plates, 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. Cylindrical roller bearings are used. Piston rings reduce air leakage through the shaft openings in the head plates, and lip-type oil seal prevent lubricant from entering the air chamber. The RCS-J incorporates thrust control, with splash oil lubrication at both ends of the blower.
Operating principles: Incoming air is trapped by the impellers. Simultaneously, pressurized air (right) is being discharged. As the lower impeller passes wrap-around flange, whispair jet equalizes pressure between trapped air and discharge area, aiding impeller movement and reducing power. Impellers move air into the discharge area (right). Backflow is controlled, resulting in reduction of noise relative to conventional blowers.
