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.

Maintenance and replacement suggestions for the air cooler kits of Atlas Copco industrial compressors: Regularly clean the dust, oil stains, and other debris on the surface of the cooler core (this can be done by blowing with compressed air or rinsing with a dedicated cleaning agent) to prevent blockages that may affect the heat dissipation effect. If there are abnormal increases in the cooling temperature after the process, leakage in the pipeline, or fan failures, it is necessary to check the condition of each component of the kit. If necessary, replace the original factory air cooler kit. During the replacement process, it must be operated by professional technicians to ensure a good installation seal, the correct fan rotation direction, and testing the cooling effect after the replacement to avoid failure in heat dissipation due to improper installation.

Key points for installation and maintenance of the check valve assembly of Atlas Copco oil-free compressors: During installation, it is necessary to assemble in accordance with the flow direction indicated by the valve body arrow. Reverse installation will cause abnormal system pressure. The oil-free system has high requirements for cleanliness. Before installation, the interfaces must be cleaned to avoid impurities from entering. When replacing the sealing parts, only original oil-free specific accessories from the manufacturer should be used. Ordinary lubricating oil is prohibited (it will contaminate the compressed air). Regular inspection (suggested every 2000 operating hours): If there are abnormal sounds during opening/closing, leakage, or excessive pressure loss, the valve core wear or spring elasticity should be checked and disassembled for inspection.

GA22 VSD Application Scenarios Suitable for industrial scenarios with significant fluctuations in gas demand, such as mechanical processing, automotive manufacturing, electronics factories, food packaging, pharmaceuticals, etc. It can consistently provide high-quality compressed air for pneumatic tools, automated production lines, inspection equipment, etc. Maintenance and Advantages The maintenance period is long. Routine maintenance includes replacing the air filter, oil filter, oil-gas separator, and special compressor oil (such as original Atlas Copco lubricating oil). The VSD technology not only saves energy but also reduces the number of motor startups and stops, prolongs equipment lifespan, and lowers maintenance frequency.

Replacement and selection suggestions for flat washers of Atlas Copco air compressors When replacing, it is necessary to strictly match the original specifications to avoid sealing failure or connection loosening due to size mismatch. For high-pressure, high-temperature or areas in contact with compressor oil, it is recommended to use original factory metal flat washers to ensure that the material is oil-resistant and pressure-resistant. If it is a critical sealing part (such as the end cover of the oil-gas separator), check whether the surface of the washer is flat, without scratches or deformation. If necessary, replace the new part to ensure the seal. For specific models or part numbers, you can refer to the parts manual of the air compressor (usually identified by a numerical code, such as 0650 series, 1622 series), or consult the Atlas Copco after-sales service for the equipment model to obtain precisely matched parts.

Faults and Maintenance Suggestions Common Problems and Solutions: Poor or blocked drainage: This is often caused by accumulated impurities. You can disassemble the valve body to clean the filter screen. In severe cases, the original valve needs to be replaced. Valve always closed or always open: This may be due to a fault in the electromagnetic valve coil or damage to the controller. You need to check the circuit and replace the corresponding components. Leakage: Caused by aging seals. It is recommended to directly replace the entire drainage valve (the original kit includes all seals). During maintenance, it is necessary to regularly (every 3 months) check if the wiring is loose, clean the drainage outlet, ensure that the winter environmental temperature is not lower than 0℃, and prevent freezing and cracking.
