Description

The single cylinder air brake compressor is a vital piston-type component that generates the compressed air required for the pneumatic braking systems in heavy commercial vehicles. This specific unit functions by taking drive from the engine to compress intake air, which is then directed to the air processing unit and storage tanks.

This 1100 035 021 is the OE equivalent of the MERCEDES BENZ 4123520250SP1, MERCEDES BENZ 9061301615SP1, WABCO 4123520020SP1, and WABCO 9061301415SP1 used in MERCEDES BENZ vehicles. It features a water-cooled housing and includes an ESS feature to ensure reliable operation under demanding heavy-duty conditions.

For professional installation, technicians should verify the water inlet/outlet port positions (M16x1,5) and ensure the M26x1,5 air ports are correctly aligned. Proper maintenance of the cooling system is essential to prevent overheating during continuous operation.

When replacing this component, always match the technical specifications such as the Ø85.00 cylinder bore and 62 mm stroke to ensure seamless integration into the existing pneumatic circuit.
