51541009903 Compatible MAN LION´S CLASSIC Air Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is an engine-driven component designed to meet the high air demand of heavy commercial vehicle brake systems. By utilizing two piston-cylinder assemblies, it delivers superior air output compared to single-cylinder units, ensuring rapid pressure buildup for critical braking functions. The unit is constructed with high-strength components to withstand rigorous operating conditions in the heavy commercial sector.

Vehicle compatibility and fitment

Designed specifically for MAN LION´S CLASSIC vehicles, this unit ensures seamless integration with the engine's pneumatic system. It features a through drive configuration and is specifically optimized for water-cooled operation to maintain thermal stability during continuous use. This compressor is an essential component for maintaining optimal pneumatic performance in demanding service environments.

Installation and maintenance guidance

The technical configuration includes a Ø100.00 cylinder bore and a 46mm stroke, providing a swept volume of 720cm³. Installation requires attention to the M26x1,5 air inlet and outlet ports, as well as the M22x1,5 water inlet and outlet ports to ensure a leak-free connection. Regular inspection of the water-cooled valve plate and cooling lines is recommended by workshop technicians to prevent system failure.

System performance and service

For optimal service life, ensure that all mounting interfaces are secure and that the cooling system remains free of obstructions. Proper maintenance of the associated air dryer and intake filters will further protect this compressor from premature wear.
