Description

Tough, low-noise bi-lobe rotary blowers

The ROOTS® RAM Series utilizes WHISPAIR™ technology to help minimize sound levels and reduce air pulsation during blower operation.

• Pressure up to 18 psig (1240 mbar)
• Vacuum up to 16” Hg (539 mbar)
• Airflow up to 3550 cfm (6030 m³/hr)

Key Features

• Removable steel mounting feet for adaptable installation
• Precision alloy steel spur timing gears
• Cylindrical roller bearings for added durability
• Piston ring-style air seals to minimize leakage
• Lip-type hydrodynamic seal on the drive shaft
• Splash-lubricated timing gears and drive-end bearings

Benefits

• Quieter Operation: The RAM WHISPAIR™ design uses integral-shaft ductile iron impellers and a specialized WHISPAIR jet to balance internal pressure, lowering noise, vibration, and energy loss.
• Strong Construction: Built with involute-profile ductile iron impellers, grey iron headplates, and a one-piece casing for maximum strength and reliability.
• Advanced Sealing Performance: Piston ring air seals and lip-style oil seals reduce the risk of leakage, while the drive shaft’s hydrodynamic seal keeps oil contained.
• Reliable Lubrication: High-strength alloy timing gears are splash-lubricated on both ends, with integrated sealing to keep air and oil flow properly separated.
• Mounting Flexibility: Steel mounting feet can be repositioned for either vertical or horizontal mounting, with extended shaft options available for specific outlet configurations.
• Extended Warranty: Covered by a 24-month warranty from initial operation or up to 30 months from shipment—whichever comes first.
