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
