Pneumatic System

How the pneumatic system
works
The pneumatic system comprises the following:
 Air supply
 Filtering system
 Controls
 Pneumatic valve box and air valves
 Air Actuators

Air Supply

Air is drawn from the chassis air tanks, passes through
an air and mist filter system (or air filter assembly) and
into the pneumatic valve box. The system runs at
approximately 120 PSI.
Figure 6-1 Air tanks

Filter System

The chassis air supply is filtered before it is used in the
control circuit. Two filters (the water filter element
and the coalescing filter [or mist filter]) are fitted on
the curbside of the chassis (see Figure 6-2). Air supply
is passed through an air filter and a mist separator, and
then routed to the pneumatic valve box.
