Figure 6-3.A maintenance index page for low-pressure air compressor systems (page 2 of 3).
Medium-pressure systems provide compressed air
within the range of 151 to 1,000 psig pressure. These
systems are not extensive and are generally provided
with individual compressors located near the loads.
Medium-pressure systems are mainly used for the
starting of diesel engines, soot blowing of boilers and
high-temperature water (HTW) generators, and
Some Navy vessels do not have a separate air
compressor to supply a direct medium-air pressure.
Instead, compressed air from HP air systems is stored in
the users air flasks (banks) at high pressure. Then when
needed, the air is routed through a pressure-reducing
