1200 020 003 Twin Cylinder Air Compressor — MAN

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's air brake system. Built with high-strength components, it utilizes a water-cooling mechanism to maintain stable operating temperatures during intensive cycles. The unit features a cylinder bore of Ø100.00 and a stroke of 46mm, delivering a total swept volume of 720cm³ to meet the rigorous demands of heavy commercial vehicle operations.

1200 020 003 is the OE-equivalent twin cylinder air compressor used in MAN (51.541.00-7237) systems. This component is specifically designed for MAN vehicles, ensuring seamless integration and maintaining the integrity of the air brake system. It is built to handle high-pressure environments common in heavy commercial transport.

For workshop technicians, this assembly features specialized port sizes including M26x1,5 for both air inlet and outlet, and M22x1,5 for water inlet and outlet. The inclusion of a water-cooled valve plate provides an extra layer of thermal protection. When performing maintenance or replacement, ensure that all connections are secure to maintain optimal pressure regulation and prevent system leaks in the pneumatic circuit.

Regular inspection of the water cooling lines and the air port integrity is recommended to ensure long-term reliability in the field.
