Ventilation of the compressor room
Non-observance of the following instructions can cause the maximum per-
mitted final compression temperature to be exceeded. The compressor will
switch itself off if this happens.
Ventilation openings (free-standing installation)
–
Position supply air intakes close to the floor.
–
Position exhaust air outlets in the ceiling or at the top of the wall.
–
The required cross sections for the supply air inlets (as well as for the flaps
and weather protection grids) are indicated in the table.
Supply air and exhaust air ducts
–
The flow velocity in the ducts should not exceed 4 m/s.
–
Never attach cooling air ducts to the compressor directly. Always use a
compensator to prevent distortion and the transmission of vibrations.
Fans
The heated exhaust air must not be drawn in again. If necessary, the heated
air must be drawn off by fans.
To ensure sufficient cooling even at high ambient temperatures, the fans must
be designed as follows:
–
The fan output must be approx. 10 – 15% greater than the sum of the re-
quired cooling air quantity for all the machinery operating in the room.
–
For a free-standing installation, the cooling air requirement specified in
the table corresponds to the required fan capacity.
CAUTION
Hazardous materials and substances!
Risk of poisoning or fire when compressing hazardous fluids.
Î
Arrange the compressor intake openings or ducts in such a way that dan-
gerous admixtures cannot be drawn in. Dangerous admixtures include
solvent vapours, dusts and other harmful substances. Avoid creating fly-
ing sparks in the vicinity of the compressor.
