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.

4.9.1.1 Option da
Compressed air aftercooler
The compressed air aftercooler lowers the compressed air temperature to only 5 K to 10 K above
the ambient temperature. The exchange of heat lowers the compressed air temperature and the
water and oil mist contained in the air precipitates to condensate. Most of the moisture carried in
the air is removed in the aftercooler. This condensate, mixed with oil particles, has to be drained by
a separator.
4.9.1.2 Option da
Centrifugal separator
A centrifugal separator is used to isolate the condensate from the compressed air. The centrifugal
separator sets the compressed air that still contains moisture into a circular movement (turbu‐
lence). The heavy dirt particles and water droplets combined in the condensate are thrown to the
outside and run down against the wall of the separator. The accumulating condensate collects at
the bottom of the centrifugal separator.
4.9.1.3 Option da
Dirt trap with condensate drain pipe
A dirt trap is located at the bottom end of the centrifugal separator. While the condensate flows
through the dirt trap, existing dirt particles are retained.
