Air treatment options
For some applications, the compressed air generated by this machine must be treated before use.
The following describes the possible air treatment options that may be fitted to the machine.
Fig. 11 Compressed air options
1
Compressed air after-cooler (Option da)
2
Cyclone separator (Option da)
3
Tool lubricator (option ea, ec)
4
Heat exchanger (Option db)
5
Filter combination (Option dd)
6
Fresh air filter (Option dc)
4.8.1.1 Option da
Aftercooler
The aftercooler lowers the compressed air temperature to only 5 K to 10 K above ambient. Most of
the moisture carried in the air is removed in the aftercooler.
4.8.1.2 Option da
Centrifugal separator
Condensate accumulating during the air cooling process is separated, fed to the exhaust gas si‐
lencer and evaporated there.
4.8.1.3 Option db
Heat exchanger
The oil/air heat exchanger is fed with hot compressor cooling oil that warms the outgoing moisture-
reduced compressed air.
This warm, dry compressed air is ideal for sand blasting, for example.
