1200 270 001 Twin Cylinder Air Compressor for MAN

What does a twin cylinder compressor do?

This twin cylinder compressor functions as a critical engine-driven component within the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate high-volume compressed air. By producing two compression strokes per crankshaft revolution, it ensures rapid reservoir filling and consistent pressure for demanding pneumatic systems. Built with high-strength components, this unit is engineered to withstand intense operating cycles in heavy-duty environments.

Vehicle compatibility and fitment

This component is compatible with MAN vehicles and is designed to meet the requirements of high-air-demand applications. It serves as an efficient replacement for original equipment, ensuring the pneumatic system maintains optimal pressure levels during operation. The design incorporates a water-cooled configuration to manage thermal loads effectively during continuous use.

Installation and maintenance

Technicians should note the specific technical parameters during installation, including the Ø35 air inlet port and the M26x1,5 air outlet port. This unit features a through drive mechanism and a water-cooled valve plate to ensure stability under high pressure. Proper alignment and secure mounting are essential to maintain the integrity of the M16x1,5 water inlet and outlet connections.

System reliability

Regular inspection of the water cooling lines and air ports is recommended to prevent leaks or pressure drops. Monitoring the performance of the ESS feature ensures that the compressor continues to provide reliable service throughout its service life in heavy commercial vehicle fleets.
