Air-injected blower for deep vacuum performance
The ROOTS® RGS-DVJ is an air injected vacuum blower engineered for demanding industrial vacuum applications. Its WHISPAIR™ discharge jet plenum introduces cool atmospheric air into the cylinder, controlling high discharge temperatures and enabling deeper vacuum operation without water injection.
Built as a heavy-duty industrial vacuum blower, the RGS-DVJ delivers vacuum levels up to 27” Hg and flows up to 16,780 SCFM. This deep vacuum rotary blower combines durable construction with integral cooling for continuous high-vacuum service.
- 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.
