4123520010 SP1 Mercedes-Benz Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a critical piston-type component that produces the compressed air required by the braking system in heavy commercial vehicles. It functions by compressing intake air and directing it to the air processing unit, ensuring consistent pressure throughout the pneumatic system. Built with heavy-duty grade materials, this unit is engineered to withstand high thermal loads during continuous operation.

Compatibility and technical specifications

This specific model is compatible with Mercedes-Benz vehicles. It features a water-cooled design with M16x1,5 inlet and outlet ports, a Ø85.00 cylinder bore, and a 62 mm stroke to provide efficient air delivery. The unit includes an ESS feature and a water-cooled valve plate to maintain optimal operating temperatures under heavy-duty conditions.

Installation and maintenance guidance

For proper installation, technicians should verify the M26x1,5 air inlet and outlet ports and ensure the M12x1,5 unloader port is correctly aligned. Given the water-cooled nature of this compressor, maintaining the integrity of the cooling circuit is essential to prevent overheating and ensure long service life.

System performance and troubleshooting

Regular inspection of the swept volume performance and port connections helps prevent sudden pressure drops in the brake system. Consult your authorized distributor to check the compatibility list.
