3969110 CUMMINS Single Cylinder, Air Compressor

The 3969110 single cylinder air compressor provides reliable air generation for critical pneumatic systems in heavy-duty environments. This component is specifically designed to maintain stable pressure through its advanced water-cooling architecture, ensuring optimal performance under high-load conditions.

This product is the OE equivalent of the CUMMINS 3969110 air compressor used in heavy commercial vehicle engine systems. It features a single cylinder design with a Ø85.00 bore and 56 mm stroke, providing a swept volume of 318cm³. The unit includes a water-cooled valve plate and specialized ports including an M27x2 air outlet and M10x1 unloader port to ensure seamless integration with the vehicle's pneumatic circuit.

For workshop technicians, this unit offers a precise fit thanks to its standardized water inlet and outlet ports (3/4" - 16 UNF). The integration of the ESS feature and through-drive design ensures long-term durability and structural integrity during operation.

Maintenance teams should regularly inspect the water-cooling connections and port seals to prevent pressure drops. Ensuring the compatibility of the M27x2 outlet with existing lines is essential for maintaining system efficiency.
