To check if the oil filter core of an air compressor is blocked, you can use the following methods:

1.

Observe the Operating Status

• Reduced Exhaust Volume: If the exhaust volume of the air compressor decreases significantly, it may indicate that the filter core is blocked, leading to reduced oil-gas separation efficiency.
• Pressure Abnormalities: If the suction pressure of the compressor abnormally increases or the pressure after the oil-gas separator rises noticeably during operation, it may suggest a blockage in the filter core.

2.

Measure Pressure Differential

• While the air compressor is running, measure the pressure differential between the inlet and outlet of the oil-gas separator.
  • Under normal conditions, the pressure differential should remain within a specific range (refer to the equipment manual for exact values).
  • If the pressure differential significantly increases, it indicates that the filter core may be blocked.
