Instruction Manual Oil-Less Compressors
8.1.1. Natural ventilation
As warm air rises, adequate wall openings should be provided for cooling air intake (next to the floor) and for
cooling air outlet (next to/ in the ceiling).
The compressor should be positioned right next to the air inlet opening.
Fig. 16: Installation with natural ventilation
A Minimum distance from wall, intake side 1.6405 ft.
B Minimum distance from wall, exhaust air side 2.46075 ft
The opening for intake air A2 should be approx. 20% larger than the opening for exhaust air A3 taking into
account louvers, grills, etc.
The table in Fig. 16 is based on the following values:
Room temperature 87°F
Temperature variation with natural ventilation 27°F
Thickness of walls 9.8425 in.
If it is not possible to follow the recommended guide lines for natural ventilation (e.g. installation of several
compressors within a very small operating room), the operating room must be ventilated artificially.
