RCS-VJ Vacuum Exhausters

ROOTS™ WHISPAIR™ water sealed vacuum exhausters are heavy duty units designed with integral shaft ductile iron impellers. WHISPAIR vacuum exhausters reduce noise and power loss by utilizing an exclusive wraparound plenum and proprietary WHISPAIR™ jet to control pressure equalization – feeding backflow in the direction of impeller movement, thereby aiding rotation.

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.
