Problem
Increased air humidity of the compressed air Contaminated air cooler.
Oil in discharge air line

In an air cooler (on the cooling air intake
side), the compressed air is cooled down to
a temperature close to the prevailing
ambient air temperature downstream of
the pressure vessel. A condensate
separator with continuous condensate
discharge is installed downstream the air-
cooler.
Attention
When there is a danger of freezing or
when the machine is switched off for a
prolonged period, any remaining
condensation must be drained from the
secondary cooler. For doing this the
bottom cover of the secondary cooler
must be opened and it must be
emptied utilising the pressure
remaining in the machine.
The oil-containing condensate has to
be collected. Do not allow to enter into
the soil or into the drains!
13.3 Maintenance instructions
Danger
Prior to and when carrying out
maintenance and repair procedures,
please do observe the general safety
regulations in chapter 3 of the
compressor operating manual.
Possible cause(s)
Aperture or silencer in condensate
separator collecting tank clogged.
See chapter 10 "Troubleshooting" in this
manual.
Aperture or silencer in filter collecting tanks
clogged.
