Replace 1621138999 Atlas Copco air filter

1621138999 replaces Atlas Copco Air filter element. It uses high-precision, high-purity wood pulp filter paper folded filter material. The large diameter design can meet the needs of high-power air compressors to filter gas. When the pressure difference between the two ends of the oil and gas Separation filter element reaches 0.15MPA, it should be replaced; when the pressure difference is 0, it indicates that the filter element is faulty or the airflow is short-circuited. At this time, the filter element should also be replaced. The general replacement time is 3000~4000 hours. If the environment is poor, its service life will be shortened.
