K034655 Freightliner CASCADIA DD15 Compressor

What does a single cylinder compressor do?

This water-cooled single cylinder compressor serves as the critical primary source of compressed air required for the pneumatic brake system in heavy commercial vehicles. By utilizing an engine-driven mechanism, it compresses intake air and distributes it to the air processing unit and storage tanks to ensure consistent braking performance.

Vehicle compatibility and engine fitment

This specific unit is designed for Freightliner CASCADIA models powered by Detroit Diesel DD15 engines. It features a water-cooled design to manage operating temperatures effectively during heavy-duty cycles, preventing overheating and ensuring long-term reliability in demanding transport environments.

Technical specifications and ports

Technical specifications include a 92.00 mm cylinder bore and a 54 mm stroke, providing a swept volume of 360cm³. The unit is equipped with an M26x1,5 air outlet port, an M18x1,5 water inlet/outlet configuration, and an M10x1 unloader port to facilitate precise system integration.

Maintenance and installation guidance

Maintenance technicians should regularly inspect the water cooling lines and port connections to prevent leaks. Ensuring the water-cooled valve plate remains clean is essential for maintaining optimal compression efficiency throughout the service life of the component.
