Air Inlet System, Functional Description - Sullair 3000P User Manual

SECTION 2
2.7 AIR INLET SYSTEM,
FUNCTIONAL DESCRIPTION
Refer to Figure 2-6. 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.
Refer to Full Load Mode - 50 to 100 PSIG (3.4 to 6.9
BAR) on page 18. The inlet valve also acts as a
check valve, thus preventing reverse rotation when
the compressor is shut down.

"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.
