Mechanical vacuum boosters are ‘Roots’ type positive displacement blowers intended for use with a backing vacuum pump. Mechanical boosters provide high pumping speed and superior final vacuum from a compact pump set.

Mechanical Boosters have a pressure bypass valve which enables the booster to be started at atmospheric pressure. The bypass valve reduces the need for pressure switches and provides faster pump down cycles. A magnetic drive between the motor and pump ensures progressive power transmission and eliminates the need for shaft seals and oil leaks associated with shaft seals.
