2. INTRODUCTION

This MEA vehicle mounted air compressor system utilizes the available hydraulic power for the running of

the installed compressor to supply compressed air at the specified flow rate and pressure.

Only those who have been properly trained and delegated to do so, and who have read and understand the

operation and installation procedures should install MEA compressor systems.

This Manual contains vital information of the compressor system and its integration into the existing hydraulic

system to ensure that it is operated in a safe and efficient manner.

The air is drawn via the intake filter, and then through the intake valve into the compression

Chamber.

In the compression chamber, the air is compressed, and oil is injected for lubrication and cooling.

The oil-air mixture then enters the separating tank in which most of the oil is separated from the air. The air

travels to the compressed air outlet via the air-oil separating element and the minimum pressure valve and

ready to be utilized.

In the air-oil separating element, the oil is filtered out down to a residual content of < 3 mg/m3 and is then

conveyed back into the compressor housing via a nozzle and the non-return valve.

When the compressor module is switched off, the minimum pressure valve

with a non-return function prevents

backflow of the compressed air out of the system into the compression chamber.

During start up a faster pressure build-up is also ensured, which is required for optimum lubrication

and oil separation.

The heat resulting during compression is dissipated via the oil-air mixture. The oil circulation also

results from the pressure difference between the outlet and inlet pressure. The optimum operating

temperature for the oil is adjusted by the integrated oil thermostat Depending on the oil temperature,

the oil thermostat valve routes the oil flow via the oil cooler or directly to the oil filter. The oil then flows via the

oil filter to the various injection points in the compressor block.
