20846000 SP1 Volvo Compatible 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 with high-strength components, it provides consistent air pressure required for reliable braking performance and system actuation. The unit is designed to withstand demanding operating conditions typical of heavy-duty transport environments.

Compatible vehicles and engines

This specific model is compatible with Volvo B11R trucks equipped with D11A engines. It is designed to match the technical requirements of the original equipment, ensuring seamless integration within the vehicle's existing air management architecture.

Installation and maintenance

For correct installation, technicians should verify that the water inlet and outlet ports (M16x1,5) align with the engine's cooling lines. Due to the through-drive configuration and specific port sizes, such as the Ø35 air inlet, matching the removed unit's specifications is essential for a proper fitment.

System integration and selection

Always ensure that the water-cooled valve plate and ESS features are checked during maintenance to prevent pressure fluctuations or overheating within the pneumatic circuit.
