5 Steps to CFAIR Air Compressor Maintenance

CFAIR diesel portable air compressors play a vital role in many applications, such as construction, mining, painting, sandblasting, etc., so it is important to keep them running efficiently. The following is a daily maintenance guide for CF190M-7, covering the replacement and maintenance of air filter elements, oil filter elements, air compressor oil, oil-gas separation elements, and cooler maintenance.

1.Replace Compressor Primary Air Filter, Safety Air Filter

The air filter surface should be cleaned regularly according to the working environment and working conditions of the air compressor. The cleaning steps are: remove the primary air filter or Safety Air Filter from the air filter housing, tap the filter element, and shake off the dust on the filter element. You can also blow from the inside to the outside with dry compressed air at a pressure not exceeding 5 bar. Generally, the normal service life of the Primary Air Filter of a CFAIR diesel air compressor is 1000 hours, and the normal service life of the Safety Air Filter is 2000 hours.

If the working conditions are relatively severe, it is recommended to shorten the replacement cycle.

2.Replace Engine Oil, Compressor Oil

Under normal circumstances, the engine lubricating oil level is between the minimum and maximum scales. If the oil level is lower than the minimum level, it must be replenished. The engine consumes oil during normal operation, and it is necessary to avoid too little oil affecting the internal lubrication of the engine. After parking, wait until all the gas in the oil and gas tank is discharged, and then observe the oil level. If the screw oil is lower than the minimum oil level, it must be replenished.

3.Replace Engine Oil Filter, Engine Fuel Filter, Compressor Oil Filter Regular

maintenance of the Engine Oil Filter, Engine Fuel Filter, and Compressor Oil Filter in a diesel air compressor is crucial for ensuring optimal performance and longevity. These filters prevent contaminants such as dirt, soot, and debris from circulating through the engine and compressor, protecting critical components from wear and tear. A clean Engine Oil Filter ensures proper lubrication, reducing friction and preventing overheating, while a well-maintained Engine Fuel Filter ensures efficient combustion by blocking impurities in the fuel, improving engine performance and exhaust reducing emissions. Similarly, a clean Compressor Oil Filter protects the compressor’s moving parts from excessive wear by ensuring proper oil flow. Regularly replacing these filters not only prevents costly breakdowns and unplanned downtime but also improves efficiency, reduces operating costs, and extends the service life of the compressor. The maintenance time for CFAIR air compressor Replace Engine Oil Filter is generally 250 hours,Replace Engine Fuel Filter is generally 250 hours, Replace Compressor Oil Filter is generally 500 hours. In essence, maintaining these components ensures smooth operation, reduces the risk of expensive repairs, and maximizes the compressor’s productivity over time.

4. Replace Compressor Separator Element

Regularly replacing the Compressor Separator Element is essential for maintaining the efficiency and longevity of an air compressor. This component ensures that oil is separated from the compressed air, preventing contamination that can damage downstream equipment and compromise air quality. A clogged or worn-out separator causes increased pressure drop, leading to higher energy consumption and reduced performance. It also risks allowing oil to bypass into the system, causing corrosion and wear on internal components. By replacing the separator element as part of routine maintenance, you ensure optimal performance, reduce downtime, prevent costly repairs, and extend the compressor’s lifespan.Generally, the maintenance period of CFAIR's Replace Compressor Separator Element is 1000 hours.

5. Fan belt and other internal parts

The tightness and surface wear of the fan belt should be checked regularly. If the belt is worn, cracked or damaged, it should be replaced in time to avoid the overall temperature of the air compressor being too high due to belt damage. The radiator surface and the air guide groove of the heat sink should be checked and cleaned regularly to avoid blockage caused by debris, dust, oil, floccules, etc., which will affect the heat dissipation effect.

In addition, each pipe joint valve and seal should be checked regularly for looseness, abnormality, oil leakage, water leakage, etc., and each electrical component and wiring harness should be checked regularly for looseness, poor contact and other abnormal conditions.

By strictly following these maintenance guidelines, the service life of the air compressor can be greatly extended, reliable performance can be ensured under various working conditions, production efficiency can be improved, and maintenance costs can be minimized. Let us consistently perform daily maintenance on the screw air compressor to keep the equipment in the best condition!
