Features

The basic high vacuum booster is constructed with a close-grained grey iron cylinder, alloy steel timing gears, ductile iron impellers and anti- friction bearings
RGS High Vacuum Boosters have four pressure lubricated single-face seals, one at each shaft, between the bearing and pumping compartment
Gears and bearings are under atmospheric pressure
A shaft driven oil pump supplies clean, cool lubricating oil to gears,
bearings and seals

Operating Principle

Incoming air is trapped by the impellers. Simultaneously, pressurized air is being discharged (right). As the lower impeller passes the wrap-around flange, WHISPAIR™ jets equalize pressure between trapped air and the discharge area, aiding impeller movement and reducing power requirements. Impellers move air into the discharge area (right). Backflow is controlled, resulting in reduction of noise relative to conventional blowers.
