What kind of oil should be used for an air compressor pump?

[DiJayden]

It mainly depends on the type of the air compressor. For small air pumps, general mechanical oil is sufficient, but the viscosity should not be too high. For compressors above 0.6 cubic meters, special air compressor oil should be used. For high-pressure or large-capacity air compressors operating continuously in factories, the oil grade specified in the manual should be selected, such as No. 32 or No. 46. There are also mineral oil, semi-synthetic oil, and full synthetic oil, chosen based on the region and the size of the air compressor. Below are some maintenance tips for air compressors: 1. Lubricant replacement: For new machines, the lubricant must be replaced after 5 hours of operation, and then every 500 hours thereafter. 2. Daily checks: Check the lubricant daily and open the drain valve of the air tank once a day to discharge oil and water. 3. Cleaning: Clean or replace the air filter element every half month, which can be adjusted based on the environment. 4. Regular inspection: Regularly check the tightness of the installed motor during use.
