A4123520270SP1 MERCEDES BENZ Twin Cylinder, Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's braking system. Designed with a high-strength component architecture, it features a water-cooled design to ensure optimal thermal regulation during intensive operation. The precision-engineered cylinder bore and specialized ports ensure reliable air delivery for heavy commercial vehicle applications.

A4123520270SP1 is the OE equivalent of the MERCEDES BENZ A4123520270SP1 twin cylinder air compressor used in MERCEDES BENZ heavy commercial vehicles. This component is specifically designed for high-demand environments where durability and consistent performance are critical for the air brake system.

For workshop technicians, this unit features a 56 mm stroke and a swept volume of 636cm³, ensuring robust output. The installation involves connecting the M26x1,5 air ports and the M16x1,5 water cooling lines. Regular inspection of the water-cooled valve plate and the unloader port (M12x1,5) is recommended during routine service intervals to maintain system integrity.

Maintenance of the air compressor system is vital for vehicle safety. Technicians should verify that the through-drive engagement and all water inlet/outlet connections are secure to prevent leaks or overheating in the pneumatic circuit.
