RGS-DVJ (Whispair) Gas Blower

Dry Vacuum Exhauster

ROOTS® DVJ WHISPAIR™ dry exhausters have an exclusive discharge jet plenum design which allows cool, atmospheric air to flow into the cylinder. This unique design permits continuous option blank-off conditions with a single blower.

  • Vacuum to 27” Hg
  • Flows to 16,780 SCFM
  • Available in v-belt or direct drive configurations
  • Rigid cast iron cylinder and headplates
  • Anti-friction cylindrical roller bearings
  • Splash lubricated spur timing gears
  • Inlet and discharge connections in standard pipe sizes
  • Involute profile ductile iron impellers
  • High Vacuum Capability: This exhauster is designed to overcome the limitations of standard dry exhausters, achieving vacuum levels beyond 16” Hg with integral cooling to prevent extreme discharge temperatures and potential equipment damage.
  • Durable Construction: The DVJ blower features grey iron headplates, gear cover, drive end cover, and one-piece casing, along with carburized alloy steel spur timing gears taper mounted on the shafts, secured with a locknut. Cylindrical roller bearings ensure robust performance.
  • 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.
