1. Lubricant quality: The quality of the lubricant directly determines the period of its use. As long as it is a lubricant produced by a regular manufacturer and qualified for quality, it can be replaced in a standard environment for 4,000 hours, while the replacement cycle for inferior lubricants is very short;
2. Humidity of air: If the humidity in the air is larger, it means that the more moisture enters the inside of the air compressor, and the mixture of moisture and lubricating oil will cause the lubricant to deteriorate, which will affect its service life;
3. Impurities: include impurities that enter with air and impurities that are generated by friction inside the air compressor. Impurities can contaminate the lubricant, causing it to fail;
