3966520 CUMMINS ISL Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent performance within the pneumatic systems of heavy-duty engines. Designed with a water-cooling system, it manages thermal loads effectively to maintain stable operation during intensive duty cycles. The component features a robust construction with a Ø85.00 cylinder bore and a 318cm³ swept volume to meet demanding industrial standards.

The 3966520 is the OE equivalent of the CUMMINS 3966520 air compressor used in high-performance engine environments. This unit is specifically designed for compatibility with CUMMINS ISL series systems. It features an air inlet port of Ø25 and an air outlet port of M27x2, ensuring precise integration with existing pneumatic lines.

For workshop technicians and fleet managers, this component offers a reliable replacement solution to maintain system pressure and prevent downtime. The through-drive design and water-cooled valve plate are optimized for long-term durability in heavy commercial applications. Regular inspection of the water inlet and outlet ports (3/4" - 16 UNF) is recommended during routine maintenance intervals.

Maintaining the integrity of the air brake compressor system is vital for vehicle safety and operational efficiency. This part provides the necessary structural strength and precision required for high-pressure air generation in heavy-duty commercial vehicles.
