20765890 Compressor for Volvo FH series D13A engines

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, providing the necessary compressed air for pneumatic braking and auxiliary functions. Built with high-strength components, this unit is engineered to withstand the demanding thermal and pressure cycles found in heavy-duty engine environments.

Compatible vehicles and engines

This component is specifically designed for Volvo FH models, including the 440, 400, 520, 480, 500, 420, 540, and 460 variants. It is also perfectly compatible with Volvo FH13 vehicles equipped with D13A engines. The unit features a water-cooled design to maintain optimal operating temperatures during continuous use.

Installation and maintenance

For proper installation and maintenance, technicians should verify all port connections, including the M26x1.5 air outlet and M16x1.5 water inlet/outlet ports. This compressor includes an ESS feature and a water-cooled valve plate to enhance durability. Ensure that the cooling system is fully functional to prevent overheating during high-load operations.

Maintenance and troubleshooting

Regular inspection of the air inlet port (Ø35) and unloader port (M16x1.5) can help prevent debris buildup and ensure consistent pressure delivery throughout the pneumatic circuit.
