The ROOTS™ RAM™-DPJ WHISPAIR™ rotary blower has an exclusive discharge jet plenum design which allows cool, pressurized system air to flow into the cylinder. This unique design permits operation at high pressure levels with a single stage unit. The RAM high pressure blower is designed for continuous operation at discharge pressures up to 30 psig. It has no valves, vanes or Teflon rings.
The basic model is designed using integral-shaft ductile iron impellers with an involute profile. The casing and headplates are grey iron, while the drive and cover and gear cover are die cast aluminum. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts, secured with a locknut. Cylindrical roller bearing are splash lubricated at both the gear end and drive end.
Piston rings reduce air leakage through the headplate bores and lip-type oil seals prevent lubricants from entering the air chamber. Mechanical seals are available upon request.
