DESCRIPTION AND OPERATION

60-11

Air Supply Unit

1 Electric motor
2 Compressor
3 Compressor temperature sensor
4 Electrical and air supply connectors

5 High pressure exhaust valve
6 Rubber mounting (3 off)
7 Exhaust hose
8 Exhaust pilot valve

The air supply unit is located in a sealed housing which is mounted in the spare wheel well. The unit is secured with 
four bolts into threaded inserts in the vehicle floorpan. The unit is connected to the system via a single air pipe and 
harness wiring and multiplug. The air pipe from the unit passes through a grommet in the wheel well. It is important 
to ensure that this grommet is not disturbed and correctly installed. Incorrect fitment will allow water to enter the wheel 
well leading to possible damage to and failure of the air supply unit.

 The unit comprises a piston compressor, a 12V electric motor, a solenoid operated exhaust pilot valve, a pressure 
relief valve and an air dryer unit.

The electric motor, compressor, air dryer and pressure limiting and exhaust valve are mounted on a frame which in 
turn is mounted on flexible rubber mountings to reduce operating noise.

Removal of the air supply unit does not require depressurisation of the air suspension system. The corner and the 
reservoir valves close, retaining the air in the system.
