3969110 CUMMINS ISC Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles. It is engineered to provide consistent air pressure through a robust single-cylinder design, ensuring the stability of the vehicle's air brake systems and other pneumatic-dependent functions. The unit features a water-cooled architecture to manage thermal loads during operation, maintaining high efficiency under heavy-duty service conditions.

3969110 is the OE-equivalent CUMMINS 3969110 single cylinder air compressor used in the CUMMINS ISC engine series. This part ensures seamless integration and maintains the original technical standards required for heavy-duty engine performance. It is designed specifically to match the precise specifications of the CUMMINS ISC engine to prevent system downtime.

For workshop technicians, this component features an Ø85.00 mm cylinder bore and a 56 mm stroke, providing a swept volume of 318cm³. The installation involves connecting to the water inlet and outlet ports (3/4" - 16 UNF) for effective cooling. The air inlet port is Ø25 and the outlet port is M27x2, allowing for direct integration into the existing air management system. Regular checks of the water cooling connections and port integrity are recommended during routine maintenance to ensure optimal service life.
