What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system, providing the necessary pneumatic pressure for heavy commercial vehicle braking operations. Built with high-strength components, this unit is designed to withstand rigorous thermal loads through its integrated water-cooling system and specialized valve plate.

Compatible vehicles and engines

This specific model is designed for use in Volvo B11R trucks equipped with D11K engines. It features a Ø85.00 mm cylinder bore and a 62 mm stroke to achieve a 704cm³ swept volume. The unit is water-cooled and includes an air unloader port of M16x1,5 and an air outlet port of M26x1,5 to ensure precise pressure regulation.

Installation and maintenance

For proper installation, technicians should verify that the water inlet and outlet ports (M16x1,5) align with the existing cooling lines. The through drive mechanism must be correctly aligned with the engine crankshaft to prevent premature wear. Regular inspection of the air unloader and cooling connections is recommended to maintain system integrity.

Troubleshooting and selection

Consult your authorized distributor to ensure exact fitment for your specific engine configuration.
