Roots Model RAM J Whispair Rotary Positive Blower Frame Size 406 J is available in stock!
RAM Whispair Rotary blowers are heavy-duty units 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. The head plates and rigid, one-piece casing are grey iron, while the drive end cover and gear cover are aluminum. 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 seals prevent lubricant from entering the air chamber. RAM Rotary blowers incorporate thrust control, with splash oil lubrication at both ends of the blower. A hydrodynamic seal on the drive shaft prevents shaft seal oil leaks. All frame sizes are designed with detachable rugged steel mounting feet which permit in-field adaptability to either vertical or horizontal installation requirements. The top shaft is extended for drive on side outlet blowers, and either shaft can be extended for drive on top or bottom outlet blowers.
