21353457 Volvo FH12 D12D Air Compressor

What does an air compressor do?

This air compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. It utilizes a single cylinder design to generate the pressurized air required for reliable braking and auxiliary pneumatic functions. Built with high-strength components, it is engineered to withstand the intense thermal and mechanical stresses found in heavy-duty engine environments.

Vehicle and engine compatibility

This specific unit is engineered for Volvo FH12 trucks equipped with D12D engines. It ensures precise air delivery through its optimized architecture, including a water-cooled valve plate for enhanced thermal management. It is also compatible with Volvo OE specifications to maintain system integrity.

Installation and maintenance

Installation requires careful attention to the water cooling connections, specifically the M16x1.5 inlet and outlet ports. Technicians should verify the M12x1.5 unloader port and the Ø35 air inlet port during assembly to ensure leak-free operation and correct pressure regulation within the braking circuit.

System monitoring

Regular monitoring of the air outlet pressure and cooling flow is recommended to prevent premature wear of the internal components.

OE cross-reference
