3969110 CUMMINS ISL Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy commercial vehicle air brake system. Designed for high-demand environments, the component features a robust water-cooled structure to maintain optimal operating temperatures and ensure long-term durability under rigorous thermal stress.

3969110 is the OE-equivalent CUMMINS single cylinder, air compressor used in the CUMMINS ISL engine systems. This part provides precise technical specifications including a Ø85.00 cylinder bore, 56 mm stroke, and a 318cm³ swept volume. It is designed to integrate seamlessly with existing engine architectures to maintain system integrity.

The assembly includes specialized ports such as the Ø25 air inlet and M27x2 air outlet to facilitate reliable airflow. Workshop technicians should note the water inlet and outlet ports (3/4" - 16 UNF) and the M10x1 unloader port during installation to ensure correct cooling and pressure regulation. Regular inspections of the water-cooled valve plate and port connections are recommended to prevent service interruptions.

This component is built using heavy-duty grade materials to withstand the vibrations and pressure fluctuations typical of heavy-duty diesel engines. By maintaining strict tolerances in the cylinder and stroke dimensions, it ensures that the air brake system receives the necessary compressed air for safe vehicle operation.
