1080437 Twin Cylinder Compressor for Volvo B12

What does a twin cylinder compressor do?

This twin cylinder compressor is a critical component of the air brake system in heavy commercial vehicles, providing the necessary compressed air to ensure braking efficiency and system stability. Designed with two piston-cylinder assemblies, it delivers a higher air output compared to single-cylinder units, allowing for faster reservoir filling and consistent pressure delivery under heavy load conditions.

Compatibility with Volvo B12 engines

This specific model is engineered for Volvo B12 engines and is compatible with the TD120 engine series. It features a water-cooled design to maintain thermal stability during sustained high-demand operations, making it suitable for heavy-duty transport applications. The unit includes a water-cooled valve plate and an ESS feature to optimize performance within the engine's cooling circuit.

Installation and technical specifications

For professional installation, technicians should verify that the M26x1.5 air ports and M16x1.5 water ports align with the existing vehicle connections. Given the 440cm³ swept volume and through-drive configuration, ensuring correct mounting and coolant flow is essential for long-term service life. Regular checks of the intake filter and cooling lines are recommended to prevent system failures.
