20382348 Volvo NH12 D12C Compressor

What does an air brake compressor do?

This air brake compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure for braking operations. Built with high-strength components, this single cylinder unit is designed to withstand the rigorous thermal and mechanical stresses found in heavy-duty engine environments.

Vehicle and engine compatibility

This specific model is designed for use in Volvo NH12 trucks equipped with D12C engines. It functions effectively within the vehicle's air supply system to maintain stable pressure levels required for safe braking performance. The unit is compatible with Volvo systems.

Technical installation and maintenance

Technicians should note the technical specifications during installation, including the Ø85.00 mm cylinder bore and the 62 mm stroke. This water-cooled unit features an M26x1.5 air outlet port and M16x1.5 water inlet/outlet ports. Proper connection of the M12x1.5 unloader port is essential for correct system operation.

Maintenance guidance

Regular inspection of the water-cooled valve plate and air ports is recommended to prevent pressure drops. Maintaining clean coolant flow through the M16 ports ensures the compressor operates within optimal temperature ranges during long-haul service.
