411 154 005 0 SP2 WABCO Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, providing the necessary compressed air for braking operations. This water-cooled unit is designed to integrate into the engine cooling circuit, which helps prevent overheating during sustained heavy-load operation and ensures consistent performance in demanding environments.

Technical specifications and cooling

This specific model is designed for high-duty cycles and features a water-cooled valve plate for enhanced thermal management. It operates via a through drive mechanism and is characterized by its Ø85.00 mm cylinder bore, a 62 mm stroke, and a swept volume of 352cm³. The air inlet port is M26x1.5, while the water inlet and outlet ports are sized at M14x1.5 to facilitate seamless installation.

Installation and maintenance

For workshop technicians, maintaining proper coolant flow through the M14x1.5 ports is essential to prevent overheating. Regular inspection of the air outlet port (Ø30) and connections is recommended to ensure there are no leaks that could compromise brake system pressure. Consult your authorized distributor for fitment guidance.

System reliability

Reliable air compression is vital for the safety of heavy commercial vehicles, as any failure in this component directly impacts brake performance and system pressure stability.
