Operation Overview
DescriptionDescription
1Compressor The compressor portion of the system includes the compressor and the components driving the compressor, such as the power
take-off (PTO). Air enters the compressor through the air filter. The air is then entrained, or mixed into the oil, and sent to the sump.
2Compressed air The compressed air portion of the system includes the sump, separator filter, and supporting hoses. The air/oil mixture moves to the
sump and separates. The separated oil collects at the bottom of the sump before being sent to the oil cooler. After the oil is cooled, it
is sent back to the compressor to repeat the cycle. The air in the sump is then moved to the separator filter. The separator filter
collects any oil remaining in the mixture and sends it back to the compressor. The compressed air is then filtered and moved to the
air distribution manifold. A port on the separator filter also sends air (pressure) to the balance valve and pressure modulation control
(PMC) assembly, where it is used to synchronize air and water pressure in auto mode.
3Cooling The cooling portion of the system includes the oil cooler, supporting hoses, fire pump, and water source. The oil moves from the
sump to the oil cooler. Flowing water circulated by the fire pump removes heat from the oil as it flows through the oil cooler. Typical
applications use an external water source to cool the compressor oil. Alternatively, an internal water source, such as an on-board
water tank, can be used to cool the compressor oil. However, an internal water source can retain heat and become less effective, so
the compressor oil temperature must be closely monitored. Depending on your application, an additional fan-style cooler may be
available to enhance the cooling capability of the system.
4Balance The balance portion of the system includes the balance valve, auto-sync solenoid assembly, PMC assembly, and supporting hoses.
When operating in auto mode, the balance valve synchronizes the air pressure produced by the compressor to the water pressure.
The balance portion of the system also purges the air from the system when operation is complete.
