Operating Principles
King Edge Vac

5.2 Compressed Air
System
It is important that the supply of compressed
air be clean and dry and at 80 psi (550 kPa). All air
is filtered before it is used. The major components
of the pneumatic system are:
Air Filter/Regulators
Air Pressure Switch
Air Reservoir
Air Valves/Air Valve Solenoids
Air Cylinders
Flow Controls
Air Bars
Pneumatic Clutch/Brake

Air Filter/Regulators
Because the condition of the compressed air
is so important, the machine includes a filter
unit equipped with a drain (Figure 5-11, A). This
helps keep the air clean and dry. This unit must
be serviced weekly for peak efficiency.
Air pressure regulators (Figure 5-11, B, Figure
5-12, A) are used to control the air pressure
for various functions. The table below lists the
original setting for each regulator. These can be
adjusted to meet specific processing needs.
Main Regulator
80 psi (550 kPa)
LH Pneumatic
60 psi (415 kPa)
RH Pneumatic
60 psi (415 kPa)
Inlet Clamps
50 psi (345 (kPa)
Left Spread Clamp
45 psi (310 kPa)
Finger Assist
30 psi (205 kPa)
Conveyor Air Assist
30 psi (205 kPa)
Air Pressure Switch
The air pressure switch (Figure 5-11, C),
located in the left endframe, ensures that the
unit has air supplied at an adequate pressure to
operate properly.
If air pressure supplied to the unit falls below
60 psi (415 kPa), the switch closes and a “low air
pressure” message displays in the CHI panel.
Air Reservoir
A crossbeam running down the center of the
machine (Figure 5-12, B) is sealed and used as an
air reservoir. This holds a supply of compressed
air for use in various parts of the machine as
required.
Air Valves/Air Valve Solenoids
The machine uses a number of air valves which
are actuated electronically by signals from the
MPC1 control board. These valves (Figure 5-12,
C, D) control the flow of compressed air to the
various air cylinders and air bars incorporated
into the unit.
