5301094 CUMMINS QSL9 Single Cylinder, Air Compressor

This single cylinder air compressor serves as a critical component within the engine system, providing consistent pneumatic pressure for heavy commercial vehicle operations. Engineered with high-strength components, the unit ensures reliable performance under intense thermal and mechanical stress. The water-cooled design utilizes specific inlet and outlet ports to maintain optimal operating temperatures during long-distance transport.

5301094 is the OE equivalent of the CUMMINS 5301094 single cylinder air compressor used in the CUMMINS QSL and QSL9 engine series. This component is engineered to meet strict technical specifications, ensuring seamless integration with existing engine architectures. The precision-engineered Ø85.00 cylinder bore and 56 mm stroke provide the necessary volumetric efficiency required for heavy-duty applications.

For workshop technicians, installation requires careful attention to the water cooling connections (3/4" - 16 UNF) and the air unloader port (M10x1). The through-drive configuration and ESS feature compatibility ensure that the assembly meets standard industrial requirements for heavy commercial vehicles. Regular maintenance checks on the air inlet (Ø25) and outlet (M27x2) ports are recommended to prevent system pressure drops or overheating issues.
