Description

Robust, adaptable, air-injected vacuum exhauster

The ROOTS® DVJ WHISPAIR™ dry vacuum exhauster features a patented discharge jet plenum that draws in cool, ambient air into the cylinder. This innovative system enables continuous operation at blank-off conditions using a single blower.

• Achieves vacuum levels up to 27” Hg (910 mbar)

Key Features

• Offered in both v-belt and direct drive options
  
• Sturdy cast iron cylinder and headplates
  
• Heavy-duty cylindrical roller anti-friction bearings
  
• Spur timing gears with splash lubrication
  
• Standard pipe-sized inlet and discharge ports
  
• Involute-profile ductile iron impellers

Benefits

• Extended Vacuum Performance: Specifically designed to exceed the 16” Hg limit of standard dry exhausters, this unit incorporates integral air cooling to prevent excessive discharge temperatures and protect downstream components.
• Sturdy Construction: Built with grey iron headplates, a single-piece casing, and heat-treated alloy steel spur gears that are taper-mounted and secured with locknuts. Cylindrical roller bearings deliver strength and longevity under demanding use.
• Reliable Sealing System: Air-tight operation is ensured with piston rings and lip-style oil seals, while a hydrodynamic shaft seal blocks lubricant from entering the airflow.
• Consistent Lubrication: Both ends of the exhauster benefit from splash oil lubrication, promoting smooth, continuous operation with minimal maintenance.
• Warranty Protection: Covered by a 12-month warranty from the initial start-up date or 18 months from the shipping date, whichever comes first.
