SECTION 2
2.7 AIR INLET SYSTEM,
FUNCTIONAL DESCRIPTION
Refer to Figure 2-4. The compressor inlet system
consists of two air filters, a compressor air inlet valve
and interconnecting piping to the engine and
compressor. Also, air filter restriction indicator
gauges are located next to the air filter housings.
The air filter is a 2-stage unit with a safety element
and dry element-type filter. This filter is capable of
cleaning extremely dirty air. However, in such cases,
frequent checks of the air filter will be required.

Figure 2-4: Air Inlet System
Referring to the controller, the engine air filter
restriction sensor or the compressor air filter
restriction sensor will indicate when restriction of the
air passing through the filter becomes too high.
At this time, change the air filter element. These
indicators should be checked daily, after start-up
under normal conditions.
The compressor air inlet valve controls the amount of
air intake of the compressor in response to the air
demand.
