Key Features

Key Features

  • Single stage operation to 27” Hg Vacuum
  • Detachable steel mounting feet
  • Alloy steel timing gears.
  • Cylindrical roller bearings.

Benefits

Benefits

  • Extended Vacuum Levels: ROOTS® DVJ WHISPAIR™ provide cooling air injection through the casing allowing for continuous option at blank-off conditions (27” Hg Vacuum) with a single blower
  • 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.
