412 704 004 0 SP1 Compatible Single Cylinder Compressor

This single cylinder air brake compressor functions as the primary source of compressed air for the pneumatic brake system. By utilizing a piston-type mechanism, it converts engine power into high-pressure air required for the air processing unit and storage tanks. This component is vital for ensuring consistent braking performance in heavy commercial vehicles.

Designed specifically for compatibility with Mercedes-Benz vehicles, this unit features a water-cooled design to maintain optimal operating temperatures under heavy-duty conditions. The technical configuration includes an M26x1,5 air inlet port, an Ø30 air outlet port, and M14x1,5 water inlet and outlet ports to facilitate seamless integration into existing pneumatic and cooling circuits.

For professional workshop technicians, ensuring proper installation is critical to prevent system leaks or overheating. When replacing this compressor, verify that the M26x1,5 intake connection and the water cooling ports align with the vehicle's existing lines. Regular inspection of the water-cooled valve plate ensures long-term reliability and prevents pressure drops in the braking system.

Consult your authorized distributor to ensure exact fitment for your specific chassis requirements.
