Replace Parker AA-J0040K air compressor filter element

Replacing the Parker AA-J0040K Air Compressor Filter element can reduce residual oil mist to as low as 0.01ppm, completely avoiding oil accumulation in Heidelberg gratings and coordinate lenses, and eliminating size drift and equipment alarms. It is an essential terminal filter element for precision machining/testing. And the dedicated hydrophobic layer will introduce condensed liquid oil-water into the bottom drain valve, which will not be carried back into the rear pipeline by the airflow, maintaining a stable and clean gas source for a long time.
