1100 225 004 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder air 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 producing multiple compression strokes per crankshaft revolution, this unit delivers significantly higher air output than single-cylinder alternatives, ensuring faster reservoir filling for high-demand systems.

Vehicle compatibility and engine fitment

This component is compatible with Mercedes-Benz vehicles and is engineered to meet the rigorous demands of the heavy commercial sector. It is specifically designed to function within integrated braking systems where consistent air pressure is vital for safety and performance.

Installation and maintenance guidance

This water-cooled unit features an air inlet port of Ø30 and an air outlet port of M26x1,5. For proper installation, technicians should verify the water inlet (M14x1,5) and outlet (M16x1,5) connections and ensure the through drive interface aligns with the engine mounting. Maintaining clean coolant flow is essential for the longevity of the water-cooled valve plate.

Troubleshooting and system checks

Regular inspection of the air unloader port (M12x1,5) and checking for leaks at the cylinder interfaces can prevent system pressure drops in heavy-duty applications.
