A4111540040SP1 MERCEDES BENZ Twin Cylinder, Air Compressor

The heavy duty twin cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure for braking and suspension functions. Designed with a robust Ø85.00 mm cylinder bore and a 56 mm stroke, this unit provides high-strength performance under demanding operational conditions.

A4111540040SP1 is the OE-equivalent of the MERCEDES BENZ A4111540040SP1 twin cylinder air compressor used in MERCEDES BENZ vehicles. This component is specifically engineered to meet the technical requirements of high-capacity air systems, maintaining structural integrity through advanced water-cooling capabilities.

For the workshop technician, this part offers a reliable installation process thanks to its standardized M26x1,5 ports and M16x1,5 water ports. Maintenance and service intervals should be conducted according to the vehicle's pneumatic system requirements to ensure optimal performance of the two-cylinder assembly.

This water-cooled unit features a specialized valve plate designed for thermal stability during continuous operation. Ensuring compatibility with the existing engine-driven drive system is essential for maintaining consistent swept volume and pressure throughout the vehicle's service life.
