21172036 Volvo B13R D13B Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system, ensuring rapid and high-capacity air generation for heavy commercial vehicle applications. Engineered with high-strength components, this unit is designed to withstand intense thermal loads through its integrated water-cooling mechanism.

Compatibility with Volvo B13R engines

This specific model is compatible with Volvo B13R trucks featuring D13B engines. It is specifically built to meet the requirements of these high-demand engines, providing stable air pressure for the braking and pneumatic systems. The unit features a through drive design and includes an ESS feature for enhanced operational reliability.

Installation and maintenance guidance

For proper installation, technicians should verify the existing engine cooling circuit connections, as this unit utilizes M16x1.5 water inlet and outlet ports. Ensure all port connections, including the M26x1.5 air outlet and M16x1.5 unloader port, are tightened to specification to prevent pressure leaks during heavy-duty operation.

System performance and selection

When replacing the unit, confirm that the swept volume of 704cm³ and the water-cooled valve plate configuration match the original equipment requirements to maintain optimal system performance.
