K035912X Freightliner Cascadia DD13 Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. It functions by compressing intake air and delivering it to the air processing unit to maintain the necessary pressure for safe braking operations. Built with high-strength components, this unit is designed to withstand the rigorous thermal and mechanical stresses found in heavy-duty engine environments.

Compatibility and engine fitment

This specific model is engineered for Freightliner Cascadia vehicles utilizing Detroit Diesel DD13 engines. It features a water-cooled design to prevent overheating during continuous operation, ensuring consistent performance under heavy loads. The unit includes an integrated ESS feature and a water-cooled valve plate to maintain optimal internal temperatures.

Technical specifications and installation

For workshop technicians, installation requires careful attention to the water inlet and outlet ports, which are sized at M18x1,5. The air outlet port features an M26x1,5 specification, while the unloader port is M10x1. This through-drive compressor has a weight of 19.8 KG and provides a swept volume of 360cm³ per cycle.

Maintenance and troubleshooting

Regular inspection of the water cooling lines and air inlet ports is recommended to prevent system contamination or overheating. Maintaining the integrity of the water-cooled valve plate is essential for preserving long-term compression efficiency in the braking circuit.
