An air compressor is the core power equipment for factories, auto repair shops, painting workshops and mining sites. Poor daily maintenance will lead to low air pressure, abnormal noise, oil leakage, frequent failures and increased energy consumption. Regular scientific maintenance can not only keep the equipment running stably 24/7, but also greatly reduce repair costs and extend the service life of the unit.

In this guide, we sort out a full set of maintenance plans for different cycles, suitable for screw compressors, piston compressors and matching air boosters.

1. Daily Maintenance (Everyday Inspection)

Simple checks before and after work, takes only 5 minutes:

- Check the oil level and oil quality, add or replace lubricating oil in time if abnormal. 

- Inspect air filters for dust and blockage.

- Check for air leakage, oil leakage and abnormal noise during operation.

- Confirm pressure gauge and temperature gauge show normal data.

- Keep the equipment and surrounding area clean, away from dust and moisture. 

2. Weekly Maintenance

- Clean the external surface and cooling system of the compressor.

- Tighten loose screws, pipelines and connectors. 

- Drain condensed water from the air tank and pipeline thoroughly.

- Check belt tension (for belt-driven models).

3. Monthly Maintenance

- Deep clean primary and secondary air filters.

- Inspect motor operation and wire connections.

- Test safety valves and pressure relief devices to ensure normal work.

- Check the working condition of the cooling fan.

4. Annual Professional Maintenance (Must-do)

- Fully replace compressor lubricating oil, oil filter and air filter.

- Inspect internal wear of cylinder, rotor and bearing.

- Calibrate pressure and temperature control systems.

- Overall inspection of the whole unit by professional technicians.

Many users ignore draining condensed water, which will corrode the air tank and affect air quality. Some use inferior lubricating oil, causing serious wear of internal parts. Avoid these wrong operations to protect your equipment.
