DVJ Whispair Exhauster

Heavy-duty, versatile, rotary blower

This WHISPAIR dry vacuum exhauster has a discharge jet plenum design which allows cool, atmospheric air to flow into the cylinder.

  • The Design permits continuous operation at vacuum levels to 20” Hg (675 mbar) with a single-stage unit.

Key Features

  • Rigid cast iron cylinder and headplates
  • Anti-friction ball bearings
  • Splash lubricated spur timing gears
  • Inlet and discharge connections in standard pipe sizes
  • Involute profile ductile iron impellers

Benefits

  • Continuous Vacuum Operation: ROOTS® DVJ WHISPAIR™ dry vacuum exhausters enable continuous operation at vacuum levels up to 20” HgV with a single stage unit.
  • Efficient Cooling Design: The exclusive discharge jet plenum design allows cool atmospheric air to flow into the cylinder, preventing extreme discharge temperatures and associated problems.
  • Heavy-Duty Construction: Built with integral-shaft ductile iron impellers, grey iron casing, headplates, and gear cover, ensuring durability and reliability.
  • Optimized Lubrication: Carburized and ground alloy steel spur timing gears are splash lubricated at the gear end and grease lubricated at the drive end for smooth operation.
  • Seal Protection: Lip-type seals are employed to restrict oil, preventing leaks and ensuring efficient operation.
  • Warranty Coverage: A warranty period of 12 months from date of original unit start-up or 18 months from date of original shipment is provided.
