Why does oil appear at the air filter of diesel screw air compressor?

DI

1.Check the air filter itself: Make sure the air filter is installed correctly and is not damaged or aged. Sometimes an aged air filter can cause oil leakage.

2.Check the intake pipe: Check whether the intake pipe is normal and there is no oil leakage or looseness. Make sure the intake pipe is well sealed.

3.Check the lubrication system: There may be a problem with the lubrication system of the diesel screw air compressor, causing oil to enter the air system. Check the pipeline and seal of the lubrication system.

4.Check the exhaust system: There may be a problem with the exhaust system, causing oil to enter the air. Check whether the exhaust pipe and valve are working properly.

5.Check the compressor itself: There may be a fault inside the diesel screw air compressor, causing oil to enter the air system. Check whether the various components of the compressor are operating normally, especially the seals and piston rings.

6.Clean the air filter and change the oil: If you find oil at the air filter, you can clean the air filter first and replace the filter element with a new one. It is also recommended to replace the lubricating oil to ensure that the oil in the system is clean and free of impurities.

7.If the problem is still not solved after the above troubleshooting methods, it is recommended to contact professional maintenance personnel for detailed fault diagnosis and repair.
