1200 040 004 MAN Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable air pressure within the pneumatic braking system of heavy commercial vehicles. Designed with high-strength components, it ensures consistent performance in demanding environments by utilizing a water-cooled mechanism to maintain optimal operating temperatures.

1200 040 004 is the OE-equivalent of the MAN 51.541.00.5 S and WABCO 412 352 003 0 S air compressor used in heavy-duty vehicle systems. This component is specifically designed to maintain compatibility with MAN and WABCO hardware, ensuring seamless integration into the vehicle's air brake infrastructure.

For workshop technicians, this part features a water-cooled valve plate and specific port dimensions including an M26x1,5 air inlet/outlet and M14x1,5 water ports. Regular inspection of the water cooling lines and air connections is recommended to ensure long-term functionality and to prevent system pressure drops during service intervals.

The assembly process requires precise alignment of the through-drive system to ensure the single-cylinder mechanism operates without mechanical interference. Maintaining the integrity of the water inlet and outlet ports is essential for effective thermal management during heavy-duty operation.
