The replacement cycle of air compressor lubricant is affected by a variety of factors, including the type of lubricating oil, the use environment and operating conditions. Here are some specific replacement cycle recommendations:

1.Mineral oil: It is usually recommended to replace it every 3 to 4 months to maintain the performance of the lubricating oil and the efficiency of the air compressor.

2.Semi-synthetic oils: Due to their better stability than mineral oils, it is recommended to replace them every 6 to 8 months.

3.Fully Synthetic Motor Oil: Due to its excellent performance and long life, it is recommended to change it every 10 to 11 months due to its long replacement interval.

4.First replacement of new machine: For newly purchased air compressors, it is recommended to replace the oil with new oil after 500 hours of first operation, and then every 2000 hours or annually.

5.Specific operating conditions: If the compressor is operating in an environment with poor air quality, corrosive gases, high temperatures, or a lot of dust in the air, the lubricant may need to be changed more frequently.

6.Operating hours: Under normal circumstances, it is recommended to change the lubricating oil after every 2000 to 4000 hours of continuous work of the air compressor.

These recommendations are based on a general situation, and the actual replacement cycle may vary depending on the specific model, frequency of use and maintenance status of the compressor.
