The air compressor is a relatively complex piece of equipment, so the maintenance cycle is strict and requires a lot of attention. It is generally divided into 4 stages: daily maintenance, monthly maintenance, quarterly maintenance, and annual maintenance.

1. Daily maintenance

It is necessary to check the pipelines for leaks every day, check the oil level, air filter element and coolant level, check whether the wearing parts have reached the replacement cycle, and replace them if so. Check the exhaust temperature of the main engine. If it has reached or is about to reach the warning temperature, clean the oil cooler and check the separator pressure difference.

2. Monthly maintenance

Check all wire connections and whether they are firm, check the AC contactor connector, clean the dust on the surface of the motor suction port and the body, clean the oil return filter, and check whether the air compressor settings are consistent with operation.

3. Quarterly maintenance

Clean the main motor and fan motor every quarter, replace the oil filter element, clean the cooler, check the minimum pressure valve, safety valve, and check the sensor.

4. Annual maintenance

Replace lubricating oil and oil-gas separator filter elements every year, replace air filter elements, oil filters, safety valve calibration, check elastic couplings, check cooling fans, clean automatic drain valves, and replenish or replace motor lubricating grease.
