A4571304615 SP1 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, providing the necessary compressed air pressure for reliable braking performance. By utilizing two piston-cylinder assemblies, this unit delivers a higher air output compared to single-cylinder designs, ensuring faster reservoir replenishment for high-demand applications.

Compatibility and technical specifications

This specific model is engineered to be compatible with Mercedes-Benz vehicles. It features a water-cooled design with a water inlet and outlet port size of M16x1,5 and an air outlet port of M26x1,5. The unit includes an ESS feature and a water-cooled valve plate to maintain optimal thermal stability during operation.

Installation and maintenance guidance

For professional installation, ensure the water cooling lines are properly connected to the M16x1,5 ports and the air inlet port (Ø30) is clear of debris. Regular inspection of the M12x1,5 unloader port and mounting integrity is recommended to prevent pressure drops in the pneumatic circuit. Check the compatibility list to confirm fitment.

System performance monitoring

Maintaining consistent air pressure requires monitoring the compressor's performance under load. If air production slows or pressure fails to reach operational levels, inspect the valve plate and cooling flow to ensure the unit functions within its intended specifications.
