Atlas Copco EWD330 Electronic Drain Valve Maintenance Recommendations Compatible Models: This product is only applicable to Atlas Copco EWD330 electronic drain valves. Before purchase, confirm the production batch and electromagnetic valve specifications of the drain valve to avoid model mismatch. Maintenance Timing: When the drain valve shows slow operation, abnormal drainage (such as no drainage or continuous drainage), abnormal noise from the electromagnetic valve, or air leakage, it may be necessary to repair the electromagnetic valve. At this time, this kit can be used to replace the worn parts. Installation Notes: It is recommended to operate by professionals. Before maintenance, cut off the power and gas sources, assemble in accordance with the original factory manual specifications, ensure that the components are installed properly, and avoid functional failures or safety hazards due to improper assembly.

Reference for common related electromagnetic valve models of Atlas Copco: Electromagnetic valves for pressure control or loading/unloading, which may use the number 1089038019 (applicable to medium and high pressure systems);

ATLAS COPCO 1621049600 Maintenance and Replacement: During regular maintenance of the air compressor, it is necessary to check the condition of the gaskets. If any deformation, aging, or damage is found, they should be replaced immediately; After disassembly, if the gasket has undergone plastic deformation (such as a metal gasket), even if it is not damaged, it is recommended to replace it to avoid repeated use leading to sealing failure; When replacing, it is necessary to use gaskets of the same specification and material as the original ones. It is prohibited to substitute with different types of gaskets (such as using a rubber gasket instead of a metal gasket). Although the air compressor gaskets are small components, they are crucial for the sealing performance of the system. Choosing the appropriate gaskets and correctly installing and maintaining them can effectively reduce leakage faults, reduce energy consumption, and extend the service life of the air compressor.

Atlas Copco Air compressor Roller Bearing Main Types and Application Scenarios Spherical roller bearings Applicable to: Rotating components such as motor rotors and fan shafts that mainly bear radial loads. Features: Simple structure, low friction coefficient, capable of simultaneously bearing certain radial and axial loads, and allowing higher rotational speeds. Cylindrical roller bearings Applicable to: Parts that bear large radial loads, such as crankshafts. Features: Strong radial load-bearing capacity, large contact area between the rolling elements and the raceways, suitable for high-load conditions, but not suitable for bearing axial loads. Angular contact ball bearings

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.

All these filter components must be equipped with original Atlas Copco parts to ensure filtration efficiency and equipment compatibility. During maintenance, it is necessary to check and replace them according to the specified cycle in the equipment manual to avoid equipment failure due to filter failure.
