Description

Robust, low-noise bi-lobe rotary blowers with gas seals

The ROOTS® RAM Series gas model is designed with mechanical seals to help limit process gas leakage and features WHISPAIR™ technology to reduce noise output and pressure pulsation during operation.

• Handles pressure up to 18 psig (1240 mbar)
• Achieves vacuum to 16” Hg (539 mbar)
• Delivers flow up to 3550 cfm (6030 m³/hr)

Key Features

• Mechanical gas seals built for handling non-corrosive gases
• Steel mounting feet that can be repositioned for flexible setup
• Precision-machined alloy steel timing gears
• Cylindrical roller bearings for high-load performance
• Hydrodynamic lip-type seal on the drive shaft to prevent oil leakage
• Splash-lubricated spur gears and bearings on both gear and drive ends

Benefits

• Engineered for Gas Applications: The RAM WHISPAIR™ gas series is purpose-built for non-corrosive gas use, incorporating advanced design features that reduce backflow, noise, and energy loss by balancing internal pressure.
• Durable Build: Constructed with integral-shaft ductile iron impellers shaped with an involute profile, supported by grey iron headplates and a rigid one-piece casing.
• Reliable Sealing Performance: Piston ring air seals and lip-type oil seals help prevent both air leakage and oil intrusion, while the hydrodynamic drive seal ensures oil containment.
• Consistent Lubrication: Alloy steel timing gears, carburized and ground for durability, are splash lubricated on both ends to support continuous, efficient operation.
• Mounting Flexibility: Easily adaptable to both horizontal and vertical mounting configurations, with optional extended shaft options to accommodate various piping layouts.
• Comprehensive Warranty: Covered for 24 months from the date of first use, or up to 30 months from the shipping date, offering confidence in long-term performance.
