20774383 Volvo B13R D13B Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is engineered to provide high-capacity air generation for heavy commercial vehicle air brake systems. By utilizing two cylinders, it ensures a rapid and stable air supply required for demanding braking and pneumatic operations. The unit is built with heavy-duty grade materials to withstand the rigorous thermal and mechanical stresses found in long-haul engine environments.

Compatible vehicles and engines

This component is specifically fitted to Volvo B13R vehicles equipped with D13B engines. It functions as a critical part of the engine's pneumatic circuit, providing the necessary pressure for the entire vehicle braking system. The design ensures seamless integration within the existing engine architecture.

Installation and maintenance

For installation, technicians should verify that the water cooling connections (M16x1,5) and air ports (M26x1,5) align with the current vehicle setup. This water-cooled model includes an integrated ESS feature and a water-cooled valve plate to maintain optimal operating temperatures during sustained heavy-load operation.

Operational stability

Regular inspection of the air inlet (Ø35) and unloader ports is recommended to prevent system contamination and ensure consistent pressure delivery.
