China ATLAS COPCO screws Manufacturer, Supplier, Factory

Maintenance points: The intake valve assembly is prone to wear of the sealing components or valve core sticking due to erosion by impurities in the air and oil-gas mixtures. Regular inspection and cleaning are required. Old seals or worn parts should be replaced. In case of necessity, the original factory components should be directly replaced to prevent the compressor efficiency from decreasing or malfunctioning.

Atlas Copco Screw Compressor Minimum Pressure Valve Assembly Original Model Selection and Notes It is necessary to select the corresponding specification of the minimum pressure valve assembly according to the compressor model (such as GA75, G110). Original factory parts (such as 1622 series, 0300 series numbers) can ensure that the pressure setting value, flow parameters, and the unit are completely matched. Non-original factory parts may cause unstable performance due to insufficient structural accuracy, and even lead to serious problems such as poor lubrication and failure of oil-gas separation. It is recommended to prioritize the use of original factory components.

Fault and Replacement Suggestions: If the thermostat valve gets stuck (unable to open or close), it will cause: Low oil temperature (always bypassing the cooler): The high viscosity of the oil increases the load on the engine and energy consumption; High oil temperature (always on the cooling): Especially in low-temperature environments, the oil heats up slowly, and the lubrication effect declines. Suggestions: When you notice abnormal oil temperature (deviating from the normal range by more than ±10℃), check the status of the thermostat valve; When there is a fault, replace the original factory thermostat valve to avoid using an alternative part that leads to insufficient temperature control accuracy; When replacing, clean the pipe interface to ensure the correct installation direction of the valve (according to the arrow indication on the valve body), to prevent installation in the wrong position from affecting the function.

Replacement and Maintenance Recommendations: Replacement Cycle: Generally, replace the filter every 1,000 - 2,000 hours or 6 months (whichever comes first). In environments with high dust concentration (such as mines, cement plants), this period should be shortened to 500 - 800 hours. Replacement Indicators: If the intake resistance becomes excessively high (over 100 - 150 mbar, which can be observed through a pressure gauge), if the compressor's exhaust volume decreases, or if there is abnormal noise from the main unit, it is necessary to immediately check and replace it. Maintenance Tips: During daily maintenance, the filter element can be removed. Use compressed air to blow off the surface dust from the inside out (pressure ≤ 5 bar), but do not wash it with water; during replacement, clean the interior of the filter housing to ensure there are no residual impurities.

Suggestions for replacement or purchase of Atlas Copco air compressor pressure switch PS3-W6S: Due to the direct correlation between pressure switch and equipment pressure control accuracy and operational safety, it is recommended to use original accessories (serial number 1624962200) to ensure compatibility. During installation, it is necessary to set the correct upper and lower pressure limits according to the equipment manual to avoid equipment failure caused by parameter errors. If you need to confirm whether it is compatible with a specific model, please provide the complete model and serial number of the compressor and contact us.

Atlas Copco also offers other types and specifications of lubricants, such as Roto Inject NDURANCE mineral oil-based compressor oil suitable for GA-GX rotary screw compressors.
