RAM-GJ (Gas/Whispair) Rotary Positive Blower

Heavy-duty, versatile, bi lobe rotary blowers with mechanical seals and reduced noise

ROOTS® RAM Series gas unit featuring mechanical gas seals to reduce process leakage through the blower and WHISPAIR™ technology to reduce noise and pressure pulsations emitted from the blower.

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

Key Features

Key Features

  • Mechanical seals designed for gas service
  • Detachable steel mounting feet
  • Alloy steel timing gears.
  • Cylindrical roller bearings.
  • Lip-type, hydrodynamic drive shaft seal.
  • Splash lubricated spur timing gears and drive end bearings.

Benefits

Benefits

  • Specialized Design: The RAM WHISPAIR line of rotary positive gas pumps is designed for non-corrosive gases, featuring proprietary design elements to reduce noise and power loss by controlling pressure equalization and eliminating rapid backflow.
  • 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.
