2.1 Operating Principle
The vacuum pump works on the rotary vane principle.
The oil seals the gaps, lubricates the vanes and takes away compression heat.
The oil filter cleans the circulating oil.
Exhaust filters separate the oil from the discharged gas.
2.2 Application
The vacuum pump 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
vacuum pump and is permissible only after a consultation with Busch.
The vacuum pump is intended for the placement in a non-hazardous environment.
The vacuum pump is capable of maintaining ultimate pressure.
The vacuum pump is suitable for continuous operation.

2.4 Features, Accessories, Options
2.4.1 Exhaust Pressure Gauge (feature)
The exhaust pressure gauge (EPG) indicates the status of the exhaust filters. Exhaust fil-
ters must be changed when the dial is in the red field.
2.4.2 Temperature Switch (feature)
The temperature switch (TS) monitors the gas temperature in the oil separator of the
vacuum pump.
The vacuum pump must be stopped when the gas temperature reaches 240 °F.
