RAS-J (Whispair) Gas Blower
Heavy-duty, versatile, rotary blowers with reduced stress, vibration and noise
ROOTS® RAS Series heavy-duty gas blowers designed for continuous service. The wraparound plenum and WHISPAIR jet handles rapid backflow of gas into the blower from the discharge area.
- Pressure to 35 psig (2413 mbar)
- Vacuum to 16” Hg (539 mbar)
- Flows to 43200 cfm (73440 m3/ hr)

Key Features
- 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
- Advanced Noise Reduction: RAS WHISPAIR rotary blowers utilize integral-shaft ductile iron impellers and a proprietary WHISPAIR jet to control pressure equalization and reduce noise, pressure pulsation and power loss.
- Heavy-Duty Construction: RAS 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.
