The air compressor oil filter is a key component of the lubrication system of an air compressor. It is mainly used to filter impurities, particles and contaminants in the lubricating oil, ensuring that the lubricating oil entering the compressor meets the cleanliness standards, thereby protecting the internal components of the compressor (such as bearings, gears, rotors, etc.) from wear and damage, and extending the service life of the equipment. Core functions Impurity filtration Intercept solid particles such as metal debris, dust, and carbon deposits, preventing them from circulating into the working components of the compressor. System protection Reduce friction and wear, lower the risk of faults caused by contaminants, and improve the reliability of the compressor. Oil life extension Remove oxidation products and moisture, delay the aging and deterioration of the lubricating oil, and reduce the frequency of oil replacement.

Maintenance Reminder: Check the valve core for any jamming (disassemble for cleaning) and the springs for fatigue every 6 to 12 months. Replace the aging seals in a timely manner. If the pressure rebounds too quickly after depressurization or cannot be completely relieved, investigate whether the valve core seal has failed or if the control signal is normal.

The oil filter element of Atlas Copco air compressors (Common Problems and Failure Causes) The filter element gets clogged prematurely Reasons: Excessive environmental dust (unfiltered intake air), excessive oil addition or mixing of different brand oils leading to emulsification, increased internal wear . Treatment: Improve environmental cleanliness, standardize oil usage, inspect worn components. Poor filtering effect Reasons: Using inferior filter elements , seal ring not properly aligned during installation , bypass valve always open. Treatment: Select original factory or high-quality aftermarket filter elements, ensure proper installation sealing, regularly check bypass valve function. Filter element rupture Reasons: Installation too tight, abnormal system pressure increase, insufficient strength of filter element material. Treatment: Standardize installation torque, check oil pressure control system, replace with qualified filter element.

Purchase Recommendation If you need to make a purchase, please provide the model number of the air compressor (such as GA55, GX15), the serial number, and the installation position of the solenoid valve (such as the intake valve, the discharge valve). Obtain precise parts from an officially authorized dealer or after-sales service center. Using non-original factory parts may lead to control failure, equipment malfunction, and even affect the overall warranty of the machine. The stable operation of the solenoid valve is the foundation of the automatic control of the air compressor. Regular inspections and timely replacements can significantly reduce the equipment failure rate and ensure gas production efficiency.

Replacement and Maintenance Recommendations: Replacement Cycle: Generally, replace the filter every 1,000 - 2,000 hours or 6 months (whichever comes first). In environments with high dust concentration (such as mines, cement plants), this period should be shortened to 500 - 800 hours. Replacement Indicators: If the intake resistance becomes excessively high (over 100 - 150 mbar, which can be observed through a pressure gauge), if the compressor's exhaust volume decreases, or if there is abnormal noise from the main unit, it is necessary to immediately check and replace it. Maintenance Tips: During daily maintenance, the filter element can be removed. Use compressed air to blow off the surface dust from the inside out (pressure ≤ 5 bar), but do not wash it with water; during replacement, clean the interior of the filter housing to ensure there are no residual impurities.

The Atlas Copco adsorption air dryer uses two towers to alternate between adsorption and regeneration, enabling continuous supply of dry air. It is suitable for applications where a lower dew point is required.
