I believe that after purchasing an air compressor, many users of air compressor equipment do not have a clear plan for the maintenance and replacement of consumables in the early stage because the air compressor is in the best initial state. Can be used without maintenance overdue.

In fact, this method is not advisable. The long-term non-maintenance and replacement of consumables for the air compressor will slowly corrode and potentially affect the actual life of the air compressor. Therefore, users are reminded that the air compressor must be maintained when it is time for maintenance. In particular, the "three filters and one oil" air compressor must be paid attention to during each period of maintenance, and the "three filters and one oil" are the core consumables for air compressor system maintenance.

The "three filters and one oil" of an air compressor refer to: air filter element, oil filter element, oil filter element and lubricating oil. They all have a specified service life, and they are generally replaced after 2000 hours of use. If you continue to use it beyond the service life, it will bring a lot of harm to the normal operation of the air compressor, affect the working performance of the air compressor, accelerate the wear and tear of other parts, and greatly reduce the service life of the air compressor.


1. Air filter

The air filter is an important protective barrier for the air compressor. It can filter out the dust and particulate impurities in the inhaled air. The cleaner the inhaled air is, the more guaranteed the performance and service life of the oil filter, oil and gas separator, lubricating oil and the main engine.

Excessive use will increase the actual compression ratio of the unit, increase the load of the main engine, and shorten the service life; excessive air filter resistance will increase the energy consumption of the unit; insufficient exhaust capacity will affect the production; the filter element is damaged and foreign matter enters the main engine. Faults that cause the machine head to lock up or even to be scrapped.

2. Oil filter

The oil filter mainly filters out particles and impurities in the air compressor lubricating oil to ensure the cleanliness of the oil circulation system and the safe operation of the air compressor system.

Excessive use will lead to insufficient lubrication of the main engine and shorten the life of the main engine; insufficient oil return will result in excessive exhaust temperature and shorten the service life of the lubricating oil. The filter element is damaged, and the unfiltered air compressor lubricating oil enters the main engine, causing the main engine to be damaged.

3. Oil and gas separator

The main function of the oil and gas separator is to separate the oil in the compressed air to ensure the quality of the compressed air.

The oil content of the compressed air produced by the overdue use increases, which affects the operation of the back-end purification equipment and the normal operation of the gas equipment, and affects the quality of the final product; poor separation efficiency, increased fuel consumption, increased operating costs, and shortages The oil will also cause the main engine to malfunction; after failure, the glass fiber will fall off and enter the lubricating oil, which shortens the life of the oil filter element and accelerates the wear of the main engine.

4. Air compressor lubricating oil

Air compressor lubricating oil mainly plays the role of lubrication, cooling, sealing, cleaning and noise reduction.

Excessive use without changing the oil will cause the machine to stop due to a high temperature alarm; the lubrication effect will deteriorate, and the wear of the main machine will be accelerated; the quality of the lubricating oil will change, and the internal coking and carbon deposits of the main machine will directly affect the service life of the air compressor.

If the "three filters and one oil" of the air compressor exceeds the service life, there will be an early warning signal during operation, but it will not shut down. However, if an early warning signal is issued, the relevant personnel should be contacted in time for maintenance and replacement. Do not change the "three filters and one oil" in time because of small losses, which will directly affect the normal operation of the air compressor, and future maintenance costs will be even greater.
