5286970 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to provide the necessary compressed air for heavy commercial vehicle braking systems. It functions by compressing intake air and directing it through the air processing unit to the storage tanks, ensuring consistent pressure for braking performance. Built with high-strength components, this unit is designed for durability in demanding environments.

Compatibility and engine integration

This water-cooled compressor is engineered to integrate seamlessly with Cummins engine configurations. It features a through-drive design and includes an ESS feature for optimized system operation. This specific model is suitable for heavy commercial vehicles requiring precise air management via its Ø85.00 mm bore and 318cm³ swept volume.

Installation and maintenance guidance

For professional installation, ensure the water inlet and outlet ports (3/4" - 16 UNF) are properly connected to the engine cooling circuit to prevent overheating. The M10x1 air unloader port and M27x2 outlet port must be checked for seal integrity during assembly. Regular inspection of the water-cooled valve plate is recommended to maintain optimal compression efficiency.
