“Oil fraction” has many names, such as oil/gas separator, oil fine separator, olein separator, olein separator, oil separator core, and people in the sector generally refer to it as oil fraction for short. Common root causes of compressor oil clogging malfunctions: Compressor oil clogging malfunctions.

- The third reason for the blockage of compressor oil:There is a problem with the sealing of the contact surface between the intake filter and the intake filter assembly. There are several causes:
- There is leakage in the middle of the intake hose: (1) The intake hose is aged and broken. (2) The intake hose is not installed properly.
- Leakage at the joint seal between the intake valve and the engine head may be due to damage to the gasket or misalignment. Root causes of compressor oil clogging breakdown Four: Too much water on the lubricant filter material root causes the filter material to swell and shrink, reducing the effective separation area of the oil, resulting in a raise in the resistance of the oil and early clogging of the oil.
The first cause of compressor oil clogging:
The environment around the compressor The environment around the compressor contains corrosive gases. For example, in some occasions, sulfide, thinner, cleaning chemicals, etc. will volatilize in the air. The high temperature of the machine itself accelerates the oxidation of the engine oil.
Once the gas enters the compressor system and reacts with the engine oil to produce carbon deposits and sludge, some impurities enter the oil circulation system and are blocked by the lubricant filter, while other impurities follow The oil-gas mixture rises to the oil, and when the gas passes through the oil.
these impurities stay on the lubricant filter paper, blocking the filter holes, and the resistance of the oil gradually increases, so that the oil needs to be replaced in a relatively short period of time. Compressor oil clogging malfunction.
The second reason for the blockage of compressor oil:
Qualified intake filter, lubricant filter, engine oil are not used, one or more conditions exist
- The intake filter with poor filtration rating will avoid some dust particles in the air from being blocked and directly enter the compressor system. The load on the lubricant filter and oil component will raise, resulting in premature blockage of the lubricant filter and oil component.
- Impurities, oil oxides, worn metal particles, etc. entering the compressor system are blocked on the filter layer of the lubricant filter due to the poor filtration rating of the lubricant filter, and the other part of the impurities has been circulating in the machine until it reaches the oil level. After separation Stuck in the filter layer of the oil, causing the oil to be blocked prematurely. There are also defective oil filters that have been used for dozens of hours, the bypass valve is opened, and the oil is not filtered in the circulation system.
- Engine oil with poor oxidation resistance should not be used. Even if the working time is short, carbon deposits and cavities will be generated to block the oil.
The third reason for the blockage of compressor oil:
There is a leak on the pipeline between the intake filter and the air inlet of the main engine:
- There is a problem with the sealing of the contact surface between the intake filter and the intake filter assembly. There are several causes:
- The intake filter is not installed properly (the size is wrong).
- The contact surface of the intake filter assembly is uneven (the intake filter assembly is deformed).
- Dirt adheres to the contact surface between the intake filter and the assembly, causing leakage. (4) The elastic contact pad on the surface of the intake filter is placed crookedly. (5) The intake filter or intake filter assembly is broken.
- There is leakage in the middle of the intake hose: (1) The intake hose is aged and broken. (2) The intake hose is not installed properly.
- Leakage at the joint seal between the intake valve and the engine head may be due to damage to the gasket or misalignment. Root causes of compressor oil clogging breakdown Four: Too much water on the lubricant filter material root causes the filter material to swell and shrink, reducing the effective separation area of the oil, resulting in a raise in the resistance of the oil and early clogging of the oil.
- The minimum pressure valve leaks. When the machine is power down, the external airflow returns to the oil along with the leak of the minimum pressure valve. Because the air pressure and temperature drop simultaneously, the gas condenses into water droplets, and the water droplets enter the oil to cause the filter material to absorb water and swell.
- The air consumption of the user is small, the load time of the compressor is short, and most of the time is in the no-load state. When the compressor is no-load, the water cannot be discharged in time, and the water stays in the lubricant filter material.
- The machine operates at a temperature lower than 75°C for a long time, so that the moisture in the inhaled air cannot be discharged and stays in the lubricant filter material for a long time. Above we have listed four common root causes of compressor oil clogging failures, hoping to help the majority of compressor users.

Frequently Asked Questions
What should I check first when a compressor will not start?
Confirm power supply, control settings, and emergency stop status, then check the pressure switch and any start protection devices.
Why does my compressor run hot?
Common causes are restricted airflow, low oil level, a blocked cooler, or high ambient temperature. Clean the cooler and verify lubrication first.
What does excessive oil consumption mean?
It usually indicates worn separator elements, overfilling, or a leak in the oil circuit. Inspect the separator and seals.
