Kaishan Compressor Air Compressor KRSD-50

NOTICE: The fluid filter maintenance indicator may read high upon start up on cool mornings due to sluggish fluid creating higher than normal differential pressures. Monitor indicator after the fluid warms up.

Check the pressure gauge reading on reservoir and wait until there is no pressure in reservoir.

Take sample at normal operating conditions or immediately after shutting unit down.

Wipe excess contamination from sample area.

WARNING: Always ensure the compressor is switched off and all air pressure is relieved before starting the maintenance.

NOTICE: Intake filtration equipment supplied from the factory may not be adequate for extremely dirty applications or some forms of dust or vapors. It is the customer’s responsibility to provide adequate filtration for those conditions. Warranty will be voided if inadequate filtration causes a failure.

Is the maintenance gauge showing red with the compressor running full load?

Has it been 4000 hours or a year since the last filter replacement?

If any of the above checks are 'PASS', proceed with the filter replacement.

Replace air/oil separator (spin on type)

The air/oil separator is a coalescent filter element. Replacement of standard type separator requires unbolting and lifting the separator cover and replacing it with a new one. The air/oil separator should be replaced as indicated in the maintenance schedule or as follows:

♦ If excessive fluid carryover is observed.

♦ 4,000 hours MAX (for spin on type), or-as indicated by differential pressure indicator.

♦ As indicated by the gauge (if equipped).

KRSD series compressors utilize a pressurized fluid drain. Use the following procedure to drain and replace the compressor fluid.

Drain water from air/oil separator tank

Check for loose fluid and air tubing, electrical wiring connection

Check equipment power supply and earth-grounding.

Replace air/oil separator (standard type).

The air/oil separator is a coalescent filter element. Replacement of standard type separator requires unbolting and lifting the separator cover and replacing it with a new one.

If excessive fluid carryover is observed.

8,000 hours MAX for standard type, or-as indicated by differential pressure indicator.

As indicated by the gauge (if equipped).
