What does a twin cylinder compressor do?

This twin cylinder compressor is an essential component of the pneumatic air brake system, responsible for providing consistent compressed air to the reservoirs. Designed for high-duty cycles, this unit utilizes two piston-cylinder assemblies to deliver higher air output compared to single-cylinder alternatives, ensuring faster reservoir replenishment for heavy commercial vehicles.

Vehicle compatibility and engine fitment

This specific model is compatible with Volvo FL12 trucks equipped with TD122 engines. It is engineered to meet the rigorous demands of heavy-duty transport, ensuring stable performance even under sustained high air demand. The unit features a water-cooled design and is optimized for integration into the engine's coolant circuit.

Technical specifications and installation

For professional installation, technicians should verify the mounting flange and port locations. This unit features an Ø89.00 mm bore and an M26x1,5 air outlet port. It is equipped with an ESS feature and a water-cooled valve plate to maintain thermal stability during operation. Ensure all connections, including the M26x1,5 outlet and M16x1,5 water ports, are tightened to specification.

Maintenance and troubleshooting
