Heavy-duty, efficient rotary blowers with minimized noise, vibration, and mechanical strain
The ROOTS® RAS Series gas blowers are engineered for continuous-duty applications. Featuring a unique wraparound plenum and integrated WHISPAIR jet, the design effectively controls the reverse flow of gas from the discharge, helping to reduce pulsations, stress, and overall operational noise.
- Supports pressures up to 35 psig (2413 mbar)
- Vacuums to 16” Hg (539 mbar)
- Delivers flows up to 43,200 cfm (73,440 m³/hr)
Key Features
- Removable heavy-duty steel mounting feet
- Precision-machined alloy steel timing gears
- Durable cylindrical roller bearings
- Piston ring air seals for controlled leakage
- Lip-type hydrodynamic shaft seal for oil retention
- Splash lubrication for timing gears and drive-end bearings
Benefits
- Superior Noise and Vibration Control: The RAS WHISPAIR rotary blower integrates ductile iron impellers and a patented WHISPAIR jet design that manages pressure balancing, helping to reduce pulsation, acoustic output, and energy loss.
- Robust Construction: Built with high-strength integral-shaft impellers, a solid one-piece casing, and grey iron headplates, the RAS Series is made to withstand demanding operating environments.
- Optimized Sealing Performance: Engineered sealing systems include piston rings and lip-type oil seals that prevent internal leakage and stop oil from entering the compression area. A hydrodynamic shaft seal provides added oil containment at the drive end.
- Consistent Lubrication: Alloy steel timing gears, carburized and ground for durability, are splash lubricated at both ends to ensure efficient, long-term operation.
- Flexible Mounting Options: The detachable mounting feet allow easy adaptation for either vertical or horizontal installation, and extended shaft configurations are available to suit different outlet requirements.
- Extended Warranty: Backed by a warranty of 24 months from the start-up date or 30 months from the shipment date, whichever occurs first.
