20382347 SP2 Volvo NH12 D12C Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it delivers a higher air volume and faster reservoir filling compared to single-cylinder alternatives. This specific unit is engineered with high-strength components to withstand the rigorous thermal and mechanical stresses found in heavy-duty engine environments.

Compatible vehicles and engines

This compressor is specifically designed for Volvo NH12 trucks equipped with D12C engines. It functions as a direct replacement for the original equipment, ensuring seamless integration with the vehicle's existing air supply and cooling architecture. The unit is compatible with Volvo systems and maintains the required performance standards for heavy-duty commercial applications.

Installation and maintenance

Installation requires precise matching of the water inlet and outlet ports, which feature M16x1,5 connections on this model. Technicians should verify the through drive configuration and the presence of the ESS feature during assembly to ensure proper system synchronization. Proper maintenance of the water cooling lines is essential to prevent overheating during continuous operation.

Selection guidance

When replacing this unit, always check the cylinder diameter and port locations against the removed component to ensure an exact fit. Consistent monitoring of air output levels can help identify early signs of wear in the valve plate or piston rings.
