NOTE
Illustrations
In this instruction manual the illustrations may differ from the machine appearance.
2.1 Operating Principle
The machine works on the Roots blower principle.
The two oil housings (on each side) allow the lubrication of the gears, bearings and in
certain versions the oil lubricated mechanical seals.
A bypass valve (BPV) limits automatically the differential pressure between inlet and out-
let.
2.2 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the
machine and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The vacuum booster is used in combination with a backing pump in vacuum system.
The machine is suitable for continuous operation.
Permitted environmental conditions, see Technical Data [►22].
NOTICE

Risk of corrosion inside the compression chamber which can reduce performance and
its lifetime!
• Check if the process gases are compatible with those following materials:
- Cast iron
- Steel
- Aluminium
