Rugged reliability for the vacuum truck industry
Gear End Driven design for greater reliability in direct drive applications.
Patented DVJ Whispair® jet allows cool, atmospheric air to flow into the cylinder for continuous operation at vacuum levels to blank-off (28″ Hg).
Cylinder casting with integral manifolds provides a compact and lightweight solution giving you more load carrying capacity.
Universal design to easily accommodate any required shaft and discharge location.
Taper-fit single-piece timing gears for reduced maintenance.
Inlet and Discharge connections in standard ANSI flanges.
