5286970 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air compressor serves as a vital component in the pneumatic braking system, converting engine power into pressurized air required for braking operations. Designed with high-strength components, this unit ensures consistent air delivery to the processing unit and storage tanks to maintain reliable braking performance in heavy commercial vehicles.

Engine compatibility and design

This specific model is engineered for compatibility with Cummins engines. The design incorporates a water-cooled valve plate and an ESS feature to manage thermal loads effectively during continuous operation in demanding environments.

Installation and technical specifications

For optimal installation, technicians should verify the 3/4 - 16 UNF water inlet and outlet ports. This unit features a through-drive design and an M10x1 air unloader port, requiring precise alignment with the engine drive to ensure maximum efficiency and prevent premature wear of the piston assembly.

Maintenance and troubleshooting

Regular inspection of the water cooling lines and air ports is recommended to prevent system pressure drops. Maintaining clean air intake and proper coolant flow helps preserve the integrity of the single-piston housing and ensures long-term service reliability.
