20765890 Volvo FM Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. Engineered to provide consistent air pressure, it utilizes a dual-cylinder configuration to ensure high-volume output and system stability under demanding operational conditions. The unit is designed with water cooling to manage thermal loads effectively during continuous operation.

Compatible vehicles and engines

This component is specifically compatible with Volvo FM series trucks, including models such as the FM 390, FM 460, and FM 500, as well as Volvo FM11 equipped with D11B engines. It is built using high-strength components to meet the rigorous requirements of heavy-duty transport and logistics fleets.

Installation and maintenance

For proper installation, technicians should verify the water inlet and outlet port connections (M16x1,5) and ensure the air outlet port (M26x1,5) is correctly seated. This unit features an integrated ESS feature and a water-cooled valve plate to maintain optimal performance levels throughout its service life.

System integration guidance

When replacing this unit, it is vital to check the current air inlet port diameter (Ø35) and ensure the through-drive configuration matches the existing engine setup to avoid system mismatching.
