8157550 SP1 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate high-volume compressed air. The unit is engineered with a 50 mm stroke and an 88.00 mm cylinder bore to provide consistent performance under demanding operating conditions. By producing two compression strokes per revolution, it ensures rapid reservoir filling for reliable braking performance.

Compatibility with Volvo F12 engines

This specific model is compatible with Volvo F12 trucks equipped with TD122 engines. It is specifically designed as a water-cooled unit to maintain thermal stability during long-haul operations, featuring an air inlet port of Ø29 and an air outlet port of M26x1,5. The unit also includes an ESS feature and a water-cooled valve plate to enhance durability.

Installation and maintenance guidance

For proper installation, technicians should verify that the water inlet and outlet ports (M16x1,5) align with the engine's coolant circuit. Ensuring the gear drive and mounting interface match the existing setup is vital for preventing leaks or mechanical slip. Regular checks of the water-cooled valve plate and port connections are recommended during routine maintenance intervals.
