SERVICE UNIT

3.3 SERVICE UNIT

    The service unit is nothing but the built in package of combination of filter, pressure regulator and lubricator.

AIR FILTER

    The purpose of air filter is to clean the compressed air of all impurities and any condensation that might be entered with the intake air and delivered by the compressor.

PRESSURE REGULATOR

    The pressure regulator are reducing valve assigned the duty of maintaining a largely constant operating regulator of  fluctuations in the air main pressure and air consumption rate. The inlet pressure must always higher than the outlet pressure.

LUBRICATOR

    The lubricator is required to ensure an adequate supply of lubricant to the pneumatic equipment. The lubrication is done by injecting the oil into the air stream. The lubricator start working only when the airflow reaches a certain rate, below which the velocity across the nozzle is to low to draw oil into the air stream. Only thin mineral oil may be used in pneumatic system lubricator. Viscosity ratings are normally 2 to 5 degree Engler at 20 degree Celsius or 10 - 50 centistrokes. The rule to be observed for complete service unit is that the flow and pressure range specified by the manufactures must be maintained or the unit must be selected to suit the given parameter of flow and pressure.
