Standard Accessories
2.4.1
Gas Ballast Valve
The gas ballast valve mixes the process gas with a limited quantity of ambient air to counteract the
condensation of vapor inside the vacuum pump.
The gas ballast valve has an influence on the ultimate pressure of the machine, see Technical Data
[
35].

Optional Accessories
2.5.1
Increased Flow Gas Ballast Valve
It increases the flow of the standard gas ballast valve to deal with high water vapor load.
2.5.2
Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The inlet filter
is available with a paper or polyester cartridge.
The clamped design makes it easy to adjust the position to the installation and the o-ring sealing
guaranties the tightness.
2.5.3
Cooling Air Deflector
It allows the cooled air from the heat exchanger (AHE) to be evacuated from the bottom of the
machine.
2.5.4
Water-oil Heat Exchanger
In case of unfavorable ambient conditions a water-oil heat exchanger can be provided.
See Cooling Water Connection (Optional) [
13].
2.5.5
Temperature Switch
The temperature switch monitors the oil temperature of the machine.
Depending on the oil type, the machine must be stopped when the oil reaches a certain
temperature, see Oil [
37].
2.5.6
Level Switch
The level switch monitors the oil level.
The machine must be stopped when the oil level is too low.
