Please refer to the following table for the cooling air requirement and size of
the supply air openings for your compressor. Ensure that flaps and weather
protection grids have the necessary free cross section. We generally recom-
mend contacting a specialist company for performing the duct construction

Table 1: cooling air requirement, necessary aperture dimensions.
* For the cooling air requirements the basis is a 4° C temperature difference between room
and outside temperature.
The air taken in contains water in form of vapour, which turns into conden-
sation during compression.
ATTENTION!
The condensate contains oil. Never lead it into the public sewage system
without prior treatment.
Strictly observe the effluent disposal laws of your local authorities.
Oil-water-seperator
The BOGE-oil-water-seperator (available as accessories) separates the oil
from the condensate.
The cleaned water may be fed directly into the public sewage system.
The oil is collected in a separate container. Dispose of the oil according to
environmental regulations.
If, due to special operating conditions, the oil should emulsify, use an emul-
sion cracking plant.
