Refer to Figure 2-7 and Figure 2-8. The compressor inlet
system consists of a dry-type air filter and an air inlet
valve.
The poppet-type air inlet valve controls the compressor's
air intake volume. Refer to Full load mode—50 to
127 psig (3.4 to 8.8 bar) on page 15. The air inlet valve
also acts as a check valve to prevent reverse rotation
when the compressor is shut down.
