Host cover shell part number 1503030000

The Atlas Copco main unit housing part number 1503030000 is a genuine original core protective component specifically designed for the GA series screw air compressors, directly compatible with the main unit assembly structure of GA models. As a critical external protective part of the main unit system, this housing serves multiple functions: firstly, it forms a sealed protective space to block external contaminants such as dust, oil, moisture, and other impurities from entering the rotor engagement area inside the main unit, preventing component wear and reduced compression efficiency caused by contaminants; secondly, it encloses the mechanical noise generated during the operation of the main unit, working in conjunction with the noise reduction design of GA models to optimize the equipment's operating environment; thirdly, it provides structural support for internal precision components such as rotors, bearings, and seals, enhancing the overall operational stability of the main unit.
As a genuine original accessory, the production of this main unit housing strictly adheres to Atlas Copco's rigorous quality standards. It is made from high-strength alloy materials or specialized engineering plastics through integrated molding, offering excellent impact resistance and corrosion resistance, making it suitable for the long-term continuous operation requirements of the GA series air compressors. The dimensional accuracy of the housing is precisely calibrated, ensuring a perfect match with the connection interfaces of the main unit casing, end covers, and other components. During installation, no additional machining or adjustments are required to achieve a tight fit, ensuring that the protective performance matches the original state of the equipment. Through the manufacturer's strict factory testing, this housing provides reliable protection for the main unit of GA models, extends the service life of core components, and ensures long-term efficient operation of the equipment.
