2.1 Operating Principle
The machine works on the two-stage rotary vane principle.
The oil seals the gaps, lubricates the vanes and takes away compression heat.
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 machine is capable of maintaining ultimate pressure.
The machine is suitable for continuous operation under certain conditions, see Continu-
ous Operation [}13].
Permitted environmental conditions see Technical Data [}23].
NOTICE
Chemical compatibility of the process gases with the machine component materials.
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
- Fluoroelastomer (FKM/FPM)
• In doubt, please contact your Busch representative.
2.3 Standard Features
2.3.1 Gas Ballast Valve
It mixes the process gas with a limited quantity of ambient air to counteract the condensation of vapour inside the machine.

• Reassemble properly the
oil mist separator.
The oil is emulsified. The machine sucked in li-
quids or significant amounts
of vapour.
• Perform a non load operation with vacuum valve
closed and gas ballast
valve open or replace the
oil.
• Modify the operational
mode, )see Conveying
Condensable Vapours
[}14]).
