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 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 17). 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 com-
pressed 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.
