412 352 027 0 S Single Cylinder Compressor for WABCO systems

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to produce the compressed air required by the pneumatic brake system in heavy commercial vehicles. By utilizing a single-piston, single-cylinder housing structure, it ensures reliable air generation for essential braking functions. The unit is engineered with high-strength components to withstand the demanding cycles of heavy-duty operation.

Compatibility and design features

This specific model is designed for use in heavy commercial vehicle applications and is compatible with WABCO systems. It features a water-cooled design to maintain stable temperatures during sustained high-load operation, which is critical for preventing overheating in demanding environments. The unit includes an ESS feature and a water-cooled valve plate to optimize efficiency.

Technical specifications and installation

Technical specifications include a cylinder bore of Ø85.00 mm, a stroke of 56 mm, and a swept volume of 352cm³. The air inlet and outlet ports are M26x1,5, while the air unloader port is M12x1,5. For installation, ensure the water inlet and outlet ports (M16x1,5) are correctly integrated into the engine cooling circuit to maintain optimal thermal management.

Maintenance and troubleshooting

To ensure proper system performance, technicians should check the through drive and unloader port connections during routine maintenance. Regular inspection of the water-cooled components helps prevent pressure drops in the pneumatic circuit, ensuring consistent braking performance for the vehicle.
