20569224 Volvo NH12 D12C Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, ensuring consistent air pressure delivery for heavy commercial vehicles. Built with high-strength components, it is engineered to withstand the rigorous thermal and mechanical demands of heavy-duty operation while maintaining optimal pressure stability.

Vehicle and engine compatibility

This specific unit is compatible with Volvo NH12 trucks, including the NH 12/340, NH 12/380, NH 12/420, and NH 12/460 variants equipped with D12C engines. It functions as a high-quality replacement for original equipment in the air brake system.

Technical specifications and installation

Maintenance technicians should note the water-cooled design and the inclusion of an ESS feature for enhanced system reliability. The unit features an air inlet port of Ø35, an air outlet port of M26x1.5, and a water inlet/outlet port of M16x1.5. Proper installation ensures efficient heat dissipation through the water-cooled valve plate.

Maintenance and system integration

Regular inspection of the unloader port (M12x1) and connections is recommended to prevent pressure drops in the pneumatic circuit.
