Description
4.1 Field of application
The device is designed for vacuum control in the rough vacuum range in laboratories and in
industry during the conveyance of gaseous media. In particular, the device is suitable for ro-
tary evaporators of all kinds.
4.2 Function
The device consists of a vacuum controller (measurement/control device) and an inte-
grated membrane vacuum pump for vacuum processes. The control is done by inputting
parameters for "setpoints" and the querying of the "actual values". This enables the control
and monitoring of the vacuum processes in various operating modes:

Vacuum pressure control for the rough vacuum range - pressure range of 1100 mbar to
2 mbar

Vacuum pressure generation via the speed-controlled vacuum pump

Adjustment of the pump speed via the speed control of the vacuum pump drive

Ventilation of the unit via the integrated ventilation valve , if necessary with inert gas (see
section 3.4 Application connections )

Protection against penetration by fluids by means of an intake separator on the suction
side

Filtering and capturing of residual gases by means of the pressure-side emission conden-
ser
4.3 Set-up
The vacuum controller with the operation and display elements is located at the top of the
device (see section
4.6.1 Operating elements and display).
