First separation: The oil-containing gas mixture, which contains various-sized oil droplets, exiting from the exhaust port of the air compressor main unit, enters the oil-gas tank. Most of the oil in the oil-gas mixture falls to the bottom of the tank under the action of centrifugal force and gravity. Second separation: The compressed air containing oil mist passes through the micrometer and fiberglass filter material layers of the oil-gas separation filter element for secondary separation. The oil particles, through the diffusion effect of the filter material, direct interception, and inertial collision and aggregation mechanisms, quickly aggregate into large oil droplets. Under the action of gravity, the oil gathers at the bottom of the oil separation element and returns to the main lubricating oil system through the bottom concave area of the secondary return oil pipe inlet, thereby making the air compressor discharge purer and oil-free compressed air.

The variable frequency solenoid valve for air compressors is a specialized control component specifically designed for variable frequency air compressor systems. It controls the opening and closing or the degree of the valve by receiving electrical signals, enabling precise regulation of key parameters such as air flow, pressure, and oil-gas circulation. In conjunction with the frequency converter, it enables the variable frequency speed regulation operation of the air compressor, thereby achieving the goals of energy saving and stable gas supply.

The air compressor oil separator is a crucial component in the air compressor system, used to separate oil droplets and oil mist from the compressed air. It ensures the purity of the compressed air and enables the recycling and reuse of the lubricating oil.

The air filter is the core component of the air intake system of an air compressor. It is mainly used to filter dust, particles, moisture and other impurities in the air that enters the compressor, preventing pollutants from entering the internal parts of the compressor (such as rotors, cylinders, valves and other key components), thereby ensuring the quality of the compressed air, reducing equipment wear and extending its service life. It is the first line of defense of the compressor's "respiratory system", together with the oil filter and oil separation core, they are called the "three filters" of the compressor, jointly maintaining the efficient and stable operation of the equipment.

The air compressor sensor is the core of the "intelligent" operation of the equipment. By accurately sensing parameters such as pressure, temperature, and flow rate, it enables the transformation from "passive maintenance" to "active prevention". Choosing the appropriate sensor and performing proper maintenance not only extends the lifespan of the air compressor but also reduces energy consumption and shortens downtime due to failures, providing stable and reliable compressed air support for industrial production.

I.Main Components Included in the Set。 Air filter Filters out dust and impurities in the air to prevent them from entering the compressor. It is recommended to replace every 4000 hours to avoid blockage that leads to a decrease in air volume and increased energy consumption. Oil filter Filters impurities in the lubricating oil to protect key components such as bearings and gears. Blockage will cause an increase in oil pressure, triggering a protective shutdown. Oil-gas separator Separates the lubricating oil from the compressed air to ensure that the exhaust contains an acceptable amount of oil (typically ≤ 3ppm). Failure will result in increased fuel consumption, oil in the exhaust, and contamination of the after-treatment equipment. Lubricating oil Synthetic lubricants (such as the SynthOil series from Atlas Copco) provide lubrication, cooling and sealing functions. They need to be replaced every 4,000 hours. Old lubricants will reduce cooling efficiency and increase the risk of carbon deposits. Sealing kit Includes O-rings, gaskets, etc., to prevent leakage of lubricating oil and compressed air. Old sealing parts may cause a decrease in pressure or oil leakage. Other accessories Some packages may include belts (belt drive type), sensors, hoses, etc. II. Advantages of the Maintenance Package One-stop purchase: A single package covers all the replacement needs of key components, avoiding the omission of accessories. Original factory matching: Atlas Copco original accessories ensure perfect compatibility with the equipment, extending the service life. Cost-effectiveness: The package price is usually more favorable than purchasing accessories separately. Professional guidance: A detailed maintenance manual is included, guiding users on how to replace the accessories correctly.
