8500006 SP1 Volvo F12 TD122 Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate compressed air. By providing two compression strokes per crankshaft revolution, this unit delivers a higher air output than single-cylinder alternatives, ensuring that pneumatic reservoirs are filled rapidly and efficiently. This specific model is engineered with a water-cooling system to maintain thermal stability during sustained high-demand operations.

Compatible vehicle and engine fitment

This unit is specifically designed for Volvo F12 trucks equipped with TD122 engines. It is built to meet the rigorous demands of heavy commercial service, ensuring consistent pressure for the pneumatic braking and auxiliary systems. The design incorporates a water-cooled valve plate and ESS features to enhance durability and operational reliability under heavy loads.

Technical specifications and installation

Technicians should note the technical specifications: this unit features an Ø88.00 cylinder bore, a 50 mm stroke, and a 608cm³ swept volume. The installation requires connection to the engine cooling circuit via M16x1,5 water inlet and outlet ports. It features an M26x1,5 air outlet port and an M22x1,5 air unloader port to ensure proper system regulation.

Selection and replacement guidance

When replacing this component, it is vital to verify that the drive type and mounting interface match the original equipment exactly. Ensuring the correct fitment prevents system leaks and maintains the integrity of the pneumatic circuit. Consult your authorized distributor.
