Ventilation and exhaust
DANGER
Danger of asphyxiation
Danger from asphyxiation due to
insufficient ventilation and exhaust.
➯
The operator must provide sufficient
ventilation and exhaust of the
compressor room.
In order to be able to dissipate the heat produced
during operation, the compressor room must have
sufficient volume and good ventilation.
The recommended minimum size of the
compressor room is 60 m
3
/ 646 ft³.
The air inlet and outlet openings should have a
minimum area of 1,8 m
2
/ 19 sq ft (for air-cooled
compressors) or x,xx m
2
/ xx sq ft (for water-
cooled compressors).
The fresh air opening should be located as low as
possible. The exhaust opening should be located
as high as possible.
Cover ventilation openings with screens in order to
prevent dirt from entering the compressor room.
The design of ventilation system is based primarily
on the required amount of cooling air. (See
"Technical data”).
If local conditions are unfavorable, install air
ducting. The flow speed of the cooling air should
not exceed 5 m/s / 16.5 ft/sec. We recommend a
minimum channel cross section of 1.8 m
2
/19 sq ft
(air-cooled compressor) and x,xx m
2
/ xx sq ft
(water-cooled compressor).
NOTE
In order to ensure good heat dissipation, the
installed auxiliary fans should be designed for
air volume about 15 to 20% greater than the
required cooling air volume for the compressor.
When installing several compressors in one
compressor room, use the sum of the required
cooling air volumes for all the compressors in
the room.
The following illustration shows the recommended
ventilation requirements.
