1188844 Volvo Twin Cylinder Air Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is a vital engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it provides efficient air production to ensure rapid reservoir filling and consistent pressure for braking systems. Built with heavy-duty grade materials, this unit is engineered to withstand the thermal and mechanical stresses typical of long-haul operations.

Vehicle and engine compatibility

This specific model is compatible with Volvo N12 trucks equipped with TD122 engines. It is specifically designed for applications requiring high-output air delivery, such as heavy-duty transport and construction machinery. The unit features a water-cooled design to maintain thermal stability during sustained high-demand cycles.

Installation and maintenance

For proper installation, technicians should verify the through drive configuration and port alignment. This unit features M26x1,5 air inlet and outlet ports, alongside M16x1,5 water inlet and outlet ports. Ensuring the coolant circuit is correctly connected to the water ports is essential for maintaining the unit's operational integrity and preventing overheating.

System performance and selection

Regular inspection of the water cooling connections and port seals is recommended to prevent pressure drops in the pneumatic system.
