20547525 SP2 Volvo NH12 D12C Compressor Equivalent

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it provides a higher air output compared to single-cylinder units, ensuring faster reservoir filling and consistent pressure for braking operations. This specific model is designed with high-strength components to withstand the rigorous thermal and mechanical demands of heavy-duty service.

Vehicle and engine compatibility

This unit is specifically fitted to Volvo NH12 trucks equipped with D12C engines. It functions seamlessly within the pneumatic system of these heavy commercial vehicles, providing the necessary compressed air for braking and auxiliary pneumatic functions. Always ensure that the mounting flange and cooling connections match the existing installation requirements.

Installation and maintenance

Installation and maintenance should be performed by a workshop technician to ensure correct alignment of the through drive and proper sealing of the M16x1,5 water ports. Regular inspection of the air inlet port and unloader valve is recommended to prevent system contamination and maintain optimal volumetric efficiency.

Selection guidance

To ensure correct fitment, technicians should verify the cylinder bore, stroke, and cooling type before replacement. Consult your authorized distributor to confirm compatibility with your specific vehicle configuration.
