Key Features
- Single stage operation to 30 psig
- Detachable steel mounting feet
- Alloy steel timing gears.
- Cylindrical roller bearings.
- Piston ring air seals.
- Lip-type, hydrodynamic drive shaft seal.
- Splash lubricated spur timing gears and drive end bearings.
Benefits
- Exclusive Discharge Jet Plenum: The ROOTS RAM DPJ WHISPAIR rotary blower features a unique discharge jet plenum design, enabling cool, pressurized system air to flow into the cylinder, allowing operation at high pressure levels with a single stage unit.
- High-Pressure Operation: Designed for continuous operation at discharge pressures up to 30 psig, the blower has no valves, vanes, or Teflon rings.
- Heavy-Duty Construction: RAM rotary blowers feature integral-shaft ductile iron impellers with an involute profile, grey iron headplates, and a rigid one-piece casing.
- Efficient Sealing Mechanisms: Piston rings and lip-type oil seals minimize air leakage and prevent lubricant from entering the air chamber, with a hydrodynamic seal on the drive shaft preventing oil leaks.
- Efficient Lubrication: Carburized and ground alloy steel spur timing gears are splash lubricated at both ends, with piston rings and lip-type oil seals preventing air leakage and lubricant entry into the air chamber.
- Versatile Mounting Options: Detachable steel mounting feet allow easy adaptation to vertical or horizontal installation requirements, with extended shafts available for different outlet configurations.
- Warranty Coverage: A warranty period of Twenty-Four months from date of original unit start-up or 30 months from date of original shipment is provided.
