gine and compressor operation and maintenance
manual for additional information on gauges and
operating parameters for the compressor.
The compressor is an oil flooded, rotary screw
type compressor. During operation, compressed
air mixed with oil flows through a cooler, then to
the compressed air tank/oil reservoir.
Compressed Air Tank/Oil Reservoir
Compressor oil separates from the air and settles
to the bottom of the compressed air tank. Com-
pressed air is stored in the upper section of the
tank and delivered to the paint system on demand.
The bottom section of the compressed air tank
serves as a reservoir for the oil that lubricates the
compressor. There is a fill fitting and sight gauge
on the lower rear side of the tank and sound shield.
The oil level should be maintained in the middle of
the sight glass. Always make sure to shutdown the
compressor and release tank air pressure before
opening the fill cap to add oil.
An in-line filter cleans the oil as it is returned to
the compressor. This filter should be changed at
regular intervals as recommended by the com-
pressor manufacturer.
The air compressor manufacturer operation man-
ual provides operation and maintenance informa-
tion for the air compressor. Refer to the Routine
Maintenance chapter for more information on the
pneumatic system.
2.5 Compressed Air Supply System
Overview
Compressed air is routed from the compressor
tank to a control manifold where it is separated
into filtered and unfiltered air circuits. Pressure
gauges on the main supply line, at each regula-
tor valve in the rear control console and on each
tank are used to monitor and control supply and
component pressures.
Solenoid activated pneumatic valves controlled
by switches on the gun control panels activate
spray gun nozzles, broom nozzles, atomization
nozzles, bead nozzles and the cylinders that raise

and lower the carriages. The valves are located in
a box mounted on the carriages.
Compressed Air Circuits
There are two compressed air circuits. Unfiltered
cooled and dried high volume air and filtered
cooled and dried air that is treated by moisture
separating filters.
