Air flow
Air is drawn through air filter (100) and is compressed by the compressor element (102) of each
compressor module. The compressed air is discharged via the check valve (104) and a common
air cooler (112).
On compressors without integrated dryer, the compressed air passes a water separator (111)
and flows to the outlet valve (121).
On standard compressors with an integrated air dryer, the compressed air flows through a
common refrigerant dryer (300) before reaching the outlet valve (121). For details on the
operation of the dryer, see section Refrigerant dryer.
Cooling
Each compressor element (102) is cooled by a radial fan (124), mounted on the drive shaft of the
compressor element. The cooling air is blown over the compressor element via a duct.
A separate electric fan (130) provides cooling air for the common air cooler (112).
Condensate management
The water separator (111) on compressors without integrated dryer has an automatic condensate
outlet and a manual drain valve.
On compressors with integrated dryer, the dryer is equipped with a water trap with an automatic
condensate outlet and a manual drain valve.
