Operator’s Manual
The system is integrated into the compressor unit, i.e. the filters and other components are mounted on the frame, the pressure
gauges are situated at the filling panel. If the SECURUS monitoring system is provided, the breathing air regeneration process and
the degree of dryness of the air are continuously monitored during the regeneration process by measuring the cartridge saturation
within the filter cartridge.
