2.7 AIR INLET SYSTEM,
FUNCTIONAL DESCRIPTION
Refer to Figure 2-5. The compressor inlet system consists
of a dry-type air filter, a restriction gauge and an air inlet
valve.
The restriction gauge (located on the air filter) indicates the
condition of the air filter by showing red when filter
maintenance is required.
The poppet-type modulating air inlet valve directly controls
the amount of air intake to the compressor in response to
the operation of the pressure regulator (see
Modulating Mode - 100 to 110 PSIG (6.9 to 7.6 BAR)
on page 12). The inlet valve also acts as a check valve,
thus preventing reverse rotation when the compressor is
shut down.
WARNING
“The Plastic Pipe Institute
recommends against the use of
thermoplastic pipe to transport
compressed air or other compressed
gases in exposed above ground
locations, e.g. in exposed plant
piping.” (I)
Sullube should not be used with PVC
piping systems. It may affect the bond
at cemented joints. Certain other
plastic materials may also be affected.
