PNEUMATIC SYSTEM
HOW THE PNEUMATIC SYSTEM WORKS
The pneumatic system includes:
• Air supply
• Filtering system
• Controls
• Valve box and air valves
• Air Actuators
Air supply
Air is drawn from the chassis air tank, passes through an air and
mist filter system and into the valve box. The system runs at
approximately 120 psi.
Filter System
The chassis air supply is filtered before it is used in the control
circuit. Two filters are fitted on the street side. Air supply is
passed through an air filter, a mist separator and then routed to
the air valve box.
• Filter elements should be replaced as per the
maintenance schedule guidelines at the beginning
of this chapter.
• The filter bowls and chassis air tanks must be
manually drained daily to remove moisture.
CAUTION
POORLY MAINTAINED PNEUMATIC CONTROL SYSTEMS ARE A MAJOR
CAUSE
OF PACKER CONTROL FAILURE.
