The Atlas Copco 2901069502 kit is designed for use for up to 4000 hours or one year. However, the lifespan of the air filter depends on the quality of lubrication and the environmental conditions.

The thermostat valve of the Atlas Copco 2205526520 oil injection type screw compressor is composed of a temperature sensing element, a valve, a valve core, spring components, sealing elements, and threaded connection ports. When the temperature of the compressor reaches the set value, the temperature sensing element triggers the valve core to open the cooling path of the cooler. Then, the lubricating oil is cooled and recirculated, which can prevent the oil from overheating and deteriorating in quality, as well as the formation of carbon deposits that cause the air compressor to have a higher temperature and affect its efficiency.

The working principle of the constant temperature valve for Atlas Copco air compressors: When the air compressor starts, the oil temperature is low. The constant temperature valve will close the oil circuit of the cooler, allowing the lubricating fluid to directly enter the main unit, rapidly increasing the temperature and reducing wear. When the temperature rises to 70-80 degrees Celsius, the constant temperature valve will slowly open the cooling channel of the cooler, allowing the lubricating oil to cool down before entering the circulation. This can prevent the oil temperature from being too high, which would lead to a decrease in lubrication effect and overheating problems of the equipment.

Maintenance and Replacement Precautions Fault Diagnosis: If the air compressor shows abnormal oil temperature (either too high or too low), or if the cooling system load is abnormal, it may be caused by the jamming of the constant temperature valve, the failure of the temperature sensing element, or poor valve core sealing. Such issues should be promptly checked. Model Matching: The constant temperature valves of different models of air compressors have differences in interface size, set temperature, and flow parameters. It is necessary to select the original factory-compatible model to avoid affecting the temperature control accuracy due to incompatible specifications.

Selection and Maintenance Tips Model Matching: Different series (such as GA, G, SF, etc.) and models of Atlas Copco equipment correspond to different specifications of filter elements. It is necessary to select the original factory filter elements based on the equipment model, flow rate, working conditions, etc., to ensure filtration efficiency and compatibility. Replacement Cycle: It is necessary to replace according to the specified cycle in the equipment manual (or based on the pollution degree of the actual operating environment). For example, air filter elements need to be shortened in the period of high dust content environments; oil filter elements are usually replaced simultaneously with the lubricating oil.

Selection and Replacement Precautions Model Matching: The sizes (inner diameter, outer diameter, thickness) of copper gaskets required for different types of air compressors and different sealing parts vary. It is necessary to select the corresponding specifications of original factory parts based on the specific model of the equipment and the sealing position to ensure a good fit. Installation Specifications: Before installation, it is necessary to clean the oil stains, impurities, and scratches on the sealing surface to avoid uneven force on the gasket due to foreign objects; when tightening the bolts, apply force evenly to prevent the gasket from being overly deformed or damaged.
