Common problems in operation and maintenance of Air Compressors:


24.What is the maintenance method of air filters element for screw air compressor?

    The air filter is equipped with a differential pressure switch. When the differential pressure reaches a set value, the differential pressure switch operates, or the internal timer time is zero, the liquid crystal display air filter is blocked. This means that the air filter must be cleaned or replaced.Maintenance should be done after the air compressor is shut down and the corresponding safety measures are taken. 

         (1) open the cover.

         (2) loosen the air filter bolt and take out the filter element.

         (3) Check the air filter plug, use compressed air from the inside out to clean up the ash, pay attention to the pressure of compressed air does not exceed 0.3 MPa.

        (4) The air filter element should be replaced when it is damaged. To detect whether the air filter is damaged, you can use electric lights placed inside the air filter and observe whether light is exposed outside.

        (5) a new air filter element should be replaced when the filter element is stained with oil.

        (6) clean or replace the filter cover and cover the cover.

        (7) check the pressure switch of air filter element is normal, preset value is not more than 50kPa.
