1200 260 001 Compatible MAN Single Cylinder Air Compressor

What does a single cylinder air compressor do?

This single cylinder air compressor serves as the primary component for generating compressed air within the pneumatic brake system. By utilizing a piston-driven mechanism, it transforms engine power into the necessary air pressure required for the air processing unit and subsequent distribution to the brake tanks. This component is essential for maintaining consistent braking performance in heavy commercial vehicles.

Compatible vehicles and engines

This specific model is compatible with MAN vehicles and meets Knorr-Bremse OE standards. It is engineered to operate within heavy-duty service cycles, ensuring that the pneumatic system receives steady air supply under varying thermal conditions. The integration of an ESS feature and water-cooled valve plate enhances its operational stability.

Installation and maintenance

For proper installation, technicians should verify the M16x1,5 water inlet and outlet ports to ensure leak-free connections. The unit features a Ø30.6 mm air inlet port and an M26x1,5 outlet port, which must be aligned correctly with the vehicle's existing pneumatic lines. Regular inspection of the unloader port and cooling connections is recommended to prevent system pressure drops.

Troubleshooting guidance

Maintaining correct cooling flow through the water ports is vital for the longevity of the internal components. If air pressure buildup is inconsistent, technicians should inspect the single cylinder housing and the valve plate for any signs of wear or debris buildup in the cooling jacket.
