2.14 TECHNICAL INFORMATION
ON THE OIL-WATER
SEPARATOR
From time to time problems occur which require a
more detailed knowledge of the OWS. Below are
some information and rules which will help you.
2.15 OPERATING INSTRUCTION
Please read all instructions carefully , especially the
paragraph “condensate flow rate“, and be sure to
comply with it. The condensate should be fed
automatically, when possible; input under pressure is
possible by means of the expansion nozzle the
device is equipped with.
2.16 INFLUENCE OF THE
COMPRESSOR OIL ON THE
EFFICIENCY
In the past compressor oils were only chosen to suit
the compressor. The problem of the condensate
disposal was hardly considered or completely
neglected. This is why many companies still use
compressor oils which emulsify strongly with water
and some of which form stable emulsion.

NOTE
1. The capacity above are maximum
figures.
2. Reduce the capacity when the
OWS is installed in difficult condi-
tions (e.g. hot dirty, dusty condi-
tions).
3. Divide capacity by 2 for conden-
sate delivered through timed sole-
noid drains.
