Key Features

• Single-stage design rated for up to 27” Hg vacuum

Benefits

• Continuous Deep Vacuum Capability: The DVJ WHISPAIR™ blower features internal air injection that cools the unit, allowing it to operate continuously even at blank-off conditions of 27” Hg vacuum using just one stage.
• Sturdy and Reliable Build: Designed with ductile iron impellers on integral shafts, supported by grey iron headplates and a single-piece casing for maximum durability.
• Advanced Sealing System: Piston ring and lip-type oil seals work together to limit air leakage and keep lubricants from entering the air stream. A hydrodynamic seal ensures oil stays contained at the drive shaft.
• Optimized Lubrication: Ground and carburized alloy timing gears are splash-lubricated on both ends for reliable, low-maintenance operation.
• Mounting Flexibility: Adjustable steel mounting feet make installation easy in either horizontal or vertical positions, with optional extended shaft designs available.
• Trusted Warranty Coverage: Backed by a 24-month warranty from start-up or up to 30 months from the original ship date—whichever comes first.
