8.2.2.2.4 Forced Ventilation

Forced ventilation should be utilized on units with drive power higher than 20 Hp. For units with lower
powered drive natural ventilation may be used. To determine the size of the required intake and exhaust
openings for forced ventilation, refer to the following table

The intake sizes given in the above table are for a cooling air velocity of 1000 ft.min. Bauer recommends that the cooling air velocity be in the range of
600 ft.min. to 2000 ft.min.
8.2.3 Intake Air
The quality of air produced by the compressor unit is directly related to the quality of air that is taken in
by the compressor. Bauer compressors require clean, dry, shop air for optimal performance. The intake air
source must be free of contaminants such as fumes, engine exhaust, and solvents. If the intake source will
be piped in adhere to the following general rules:
• Use PVC or similar material that will not corrode and contaminate the incoming air.
• The entire run should be the same sized piping
• Install a moisture trap with a drain prior to the compressor inlet
• If using glue on the piping, allow sufficient time for the vapors to dissipate before using the com-
pressor
8.2.3.1 Inside Air Source
The location of the compressor and its air intake are significant to the quality of the air produced and the
performance of the purification system. Locating the air intake near other heat producing equipment must
be avoided when possible. A close proximity to water heaters, boilers, and such are potential contami-
nates to the quality of the processed air. Purification cartridge lifespans are dramatically reduced when
the processed air's temperature is elevated. Inadequate ventilation reduces the ability of the compressor
to cool itself or the air being compressed.
