6229031700 The non-return valve C77 of the oil-injected screw compressor from Atlas Copco reduces the impact of the backflow airflow on the internal components of the compressor, such as rotors and bearings, thereby extending the service life of the equipment.

When purchasing the Atlas Copco air compressor part 2906097200, please make sure to purchase it in accordance with our Atlas Copco manual and the corresponding model. If you have any questions, I will match you with the original genuine product and the corresponding price.

If you need to purchase the 2906041800 ATLAS COPCO drive shaft sealing kit, please contact us to purchase genuine original parts. Avoid using non-compliant products that may cause leakage and impurities to enter, thereby affecting the normal operation of the air compressor.

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.
