2 General description
2.1
Introduction
Compressed air produced by oil-injected compressors contains a small quantity of oil. During the cooling of
the air in the aftercooler and in the refrigeration dryer (on compressors with built-in refrigeration dryer), oil-
containing condensate is formed.
OSC are condensate treatment devices, designed to separate the major part of this oil from the condensate
and absorb it in filters.
They are insensitive to shocks and vibration because of the use of filters and can be used with all types of
drains. The condensate meets the requirements of the environmental codes.
The number in the model designation is the air capacity of the compressor in litres per second (see section
Technical data).
OSC 35 up to OSC 145 have two towers and are called two-step units.
OSC 355 up to OSC 1200 have three towers and are called three-step units.
OSC 2400 have six towers. They consist of two three-step units.
