In the air compressor system, the oil filter's main function is to filter out metal particles, impurities, etc., from the lubricating oil, ensuring the cleanliness of the oil circulation system and the normal operation of the equipment. If the oil filter malfunctions, it will inevitably affect the use of the equipment.

Oil filter replacement criteria:

1. Replace when the actual usage time reaches the designed lifespan. The designed service life of the oil filter element is typically 2000 hours. It must be replaced upon expiration. Additionally, external conditions such as prolonged non-replacement of the oil filter or excessively harsh working conditions may cause the filter element to break. If the environment around the air compressor room is relatively harsh, the replacement interval should be shortened. When replacing the oil filter, follow each step in the user manual sequentially.

2. Replace the oil filter element promptly when it becomes clogged. The clogging alarm set value for the oil filter element is usually 1.0-1.4 bar.

Hazards of overdue use of the air compressor oil filter element:

1. After clogging, insufficient oil return leads to excessively high exhaust temperatures, shortening the service life of the oil and oil separator element.

2. After clogging, insufficient oil return leads to inadequate lubrication of the main unit, shortening the main unit's service life.

3. After the filter element is damaged, unfiltered oil containing a large amount of metal particles and impurities enters the main unit, causing severe damage to the main unit.

The above describes the role of the air compressor oil filter and the hazards of overdue use. In daily work, it is essential to regularly inspect and maintain the equipment to extend the service life of the air compressor.
