3968694 Compatible ISLe Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a vital component in the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-type mechanism, it compresses intake air to provide the necessary pressure for the air processing unit and storage tanks. The unit is built with high-strength components to withstand rigorous duty cycles and ensures consistent air delivery for braking performance.

Compatibility with Cummins engines

This specific model is compatible with Cummins engines, specifically the ISLe, ISDe, and ISBe series. Its design features a water-cooled valve plate and an integrated ESS feature to maintain optimal operating temperatures during sustained heavy-load operation. This ensures the component functions reliably within the engine's cooling circuit.

Technical specifications and installation

Installation and maintenance require attention to the specific port dimensions. This unit features an M26x1.5 air inlet port, an M22x1.5 air outlet port, and an M12x1.5 unloader port. The water connection utilizes M16x1.5 ports for both inlet and outlet to ensure proper thermal management. Regular inspection of the through drive and port seals is recommended to prevent pressure drops.

Maintenance and system integration

Consult your authorized distributor for compatibility verification.
