Dry Vacuum Exhauster

ROOTS® DVJ WHISPAIR™ dry exhausters incorporate a specialized discharge jet plenum that channels ambient air into the cylinder. This distinctive airflow system supports continuous operation under blank-off vacuum conditions using a single unit.

• Vacuum to 27” Hg
• Flows to 16,780 SCFM

Key Features

• Compatible with both v-belt and direct drive setups
  
• Sturdy cast iron construction for cylinder and headplates
  
• Anti-friction cylindrical roller bearings for enhanced durability
  
• Splash-lubricated spur timing gears for dependable operation
  
• Standard pipe-sized inlet and discharge ports
  
• High-efficiency involute profile ductile iron impellers

Benefits

• Enhanced Vacuum Performance: Engineered to exceed the limits of conventional dry exhausters, this unit can sustain vacuum levels greater than 16” Hg, with integrated air cooling to manage heat buildup and avoid potential system damage.
• Rugged Design: The DVJ unit is constructed with grey iron components including headplates and casing, supported by carburized alloy steel timing gears taper-mounted and secured by locknuts. Cylindrical roller bearings ensure long-term resilience.
• Optimized Sealing: Piston ring air seals and lip-type oil seals effectively prevent air leaks and keep lubricants from entering the compression chamber. A hydrodynamic seal on the drive shaft adds extra protection against oil escape.
• Reliable Lubrication System: Splash oil lubrication at both ends ensures smooth, consistent performance under continuous operation.
• Warranty Assurance: Comes with a 12-month warranty from initial startup or up to 18 months from shipment date—whichever comes first.
