1100 330 003 Detroit Diesel Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a vital component in the pneumatic system of heavy commercial vehicles, providing the necessary compressed air for braking operations. It features a robust water-cooled design to ensure stable performance under high-load conditions, preventing overheating during sustained operation. The unit includes a water-cooled valve plate and an integrated ESS feature to optimize air delivery efficiency.

Compatible vehicles and engines

This compressor is engineered for compatibility with Detroit Diesel DD15 engines found in various heavy-duty vehicles, including Western Star 4900, 49X, 5700XE, and 57X models. It is also fitted to Freightliner CASCADIA, COLUMBIA, CORONADO, CENTURY CLASS, 114SD, and 122SD trucks. This ensures reliable air pressure generation across a wide range of heavy commercial applications.

Installation and maintenance

For optimal maintenance, technicians should inspect the water inlet and outlet ports (M18x1.5) and the air outlet port (M26x1.5) to prevent leaks. Given the through-drive configuration and water-cooled architecture, ensuring proper coolant flow is essential to maintain the longevity of the internal components like the piston and ring assembly.

Troubleshooting and selection

Proper selection ensures that the air consumption requirements of the vehicle's braking system are met without premature wear of the compressor components.
