8150407 SP1 Volvo Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is an engine-driven unit in the air brake system of heavy commercial vehicles that generates compressed air using two piston-cylinder assemblies.

Compatibility and technical specifications

Designed specifically for Volvo F12 models equipped with TD122 engines, this unit features a through-drive configuration and a water-cooled design to maintain thermal stability during high-demand operation. Technical specifications include a 75.00 mm cylinder bore, a 50 mm stroke, and a swept volume of 440cm³. The unit is equipped with M26x1.5 air inlet and outlet ports, alongside an M22x1.5 air unloader port, ensuring precise pneumatic control.

Installation and maintenance guidance

For professional technicians, installation requires verifying the cooling circuit connections via the M16x1.5 water inlet and outlet ports. Because this is a water-cooled unit with a water-cooled valve plate, ensuring proper coolant flow is vital for longevity. When replacing the unit, always confirm that the drive gear and mounting interface match the existing installation to ensure correct synchronization with the engine.

System performance and troubleshooting

Proper maintenance of the air brake system includes regular checks of the air ports and unloader valves to prevent pressure drops in the braking circuit.
