6.5 Vacuum gauge
The vacuum gauge is mounted in the outlet line of the filter and measures negative pressure
(vacuum) downstream of the filter. You can use the vacuum gauge as a pollution indicator for the
filter element.
To use the gauge as pollution filter you have to install an unused filter element to the filter. Launch
the filter system and adjust the drag indicator to the preset value. We recommend to set a pressure
rise of 200 mbar as alarm value.
6.6 Bowl
Plastic bowls (PA) are standard for SWK 2000/5, SWK 2000/10
and 2000/18. Aluminium bowls are available for those models as
an option.
For models SWK 2000/40 and SWK 2000/130 only aluminium is
available.
The advantage of transparent plastic bowl is that you can
evaluate the water level and the degree of contamination of the
collecting area without sensors.
The metal bowl is for harsher requirements and is resistant to broader range of temperatures and
chemicals.
