Product core information

Function and Effect

As a key filtering component of the oil circulation system, it can effectively intercept metal debris, carbon particles, oil sludge and other impurities in the lubricating oil (with a filtration accuracy usually ranging from 10 to 20 micrometers), preventing impurities from entering the main rotor, bearings and other precision parts and causing wear. At the same time, it maintains the cleanliness and lubrication performance of the lubricating oil, and extends the service life of the oil and the equipment.

Applicable Models

Mainly suitable for the specific series of oil-injected screw air compressors of Atlas Copco (such as GA, G series, etc.). The specific applicable models need to be referred to in the equipment manual or confirmed through the serial number to ensure compatibility with the oil circulation system specifications of the air compressor.

Replacement and Maintenance Tips

Replacement Cycle: It is generally recommended to replace the filter every 1,000-2,000 hours or every 6 months (whichever comes first). If the operating environment is harsh (such as high dust, high temperature), the replacement cycle should be shortened.

Replacement Procedure:

Before replacement, the machine should be shut down and depressurized. Wait for the oil to cool down before operating. Avoid scalding from hot oil.

When removing the old filter, collect the residual oil; before installing the new filter, check if the sealing ring is intact. A small amount of clean lubricating oil can be applied to the sealing ring to enhance the sealing performance.

Tighten according to the specified torque to avoid over-tightening and damaging the filter seat or under-tightening and causing leakage.

Post-replacement Inspection: After starting the machine, observe if there is any leakage around the filter seat. During the initial operation, pay attention to the oil filter pressure difference gauge (if available) to confirm normal operation.
