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

Key Features
- 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
Benefits
- 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.
- Effective Lubrication: The vacuum exhausters incorporate splash oil lubrication at both ends for smooth and reliable performance.
- 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.
