2.5. Pneumatic Air Flow
The compressor has two elements where moisture and / or condensate is removed.
2.5.1. Intermediate Stage Condensate Collector and Drain.
A condensate drain is positioned after the first stage intercooler, prior to the intake for
the second stage.
2.5.2. Final Condensate Collector, Drain and Filter.
The filter housing contains both the Final Condensate Collector as well as the air filter.
One key element used in the condensate collector is the sintered filter. A conical syn-
thetic sintered filter is installed in the base of the filter housing. Air enters the housing
after the 3
rd
stage and the aftercooler, and flows through the sintered filter where oil and
moisture condense on the interior surface of the sintered filter, and fall to the base of the
condensate collector. The moisture and oil that is captured here are contaminants that
need not be captured by the filter, extending its effective service life.
An additional benefit of using the sintered filter
prior to the filter cartridge is that the air that exits
the sintered filter and flows thru the molecular sieve
filter has an even velocity across the surface of the
filter as it enters the filter. This avoids the creation
of a high velocity path thru the filter material. Con-
stant air velocity permits optimum effectiveness of
and utilization of the molecular sieve material
