3957726 ISLe Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, providing the necessary compressed air for braking performance. It utilizes a piston-type mechanism to compress intake air, which is then distributed to the air processing unit and storage tanks. Built with high-strength components, this unit ensures reliable pressure generation even under demanding operational conditions.

Engine compatibility and fitment

This specific model is designed for use with Cummins ISLe, ISDe, and ISBe engines. It features a water-cooled configuration to prevent overheating during sustained heavy-duty cycles, ensuring consistent air output. The assembly includes a water-cooled valve plate and integrated ESS features to maintain system stability.

Technical specifications and installation

Technical specifications include a Ø80.00 mm cylinder bore and a 45mm stroke, resulting in a swept volume of 225cm³. For proper installation, technicians should verify the M26x1,5 air inlet port and M22x1,5 air outlet port connections. Ensure the water inlet and outlet ports (M16x1,5) are correctly integrated into the engine cooling circuit to maintain optimal thermal regulation.

Maintenance and troubleshooting

Regular inspection of the unloader port (M10x1) and water lines is recommended to prevent pressure drops or overheating. Consult your authorized distributor to ensure correct fitment for your specific engine series.
