A9061301815 MERCEDES BENZ CITARO O530 OM909 Air Compressor

The technical function of this twin cylinder air compressor is to provide consistent compressed air to the vehicle's pneumatic systems, ensuring reliable braking and suspension performance. Constructed with heavy-duty grade materials, it is designed to maintain high pressure even under rigorous operating conditions. The unit features a specialized water-cooling architecture to prevent overheating during extended service cycles.

A9061301815 is the OE equivalent of the MERCEDES BENZ A9061301815 twin cylinder air compressor used in the MERCEDES BENZ CITARO O530 OM909 engine. This component is engineered to meet exact technical specifications, including a 636cm³ swept volume and a specific configuration for through-drive compatibility. It is essential for maintaining the pneumatic integrity of the heavy commercial vehicle chassis.

Workshop technicians should ensure that all port connections—including the Ø30 air inlet and M26x1,5 outlet—are properly seated to prevent leaks. Given its water-cooled nature, maintaining the integrity of the M14x1,5 and M16x1,5 water ports is critical for thermal stability. Regular inspections of the unloader port and cooling lines are recommended during standard heavy commercial vehicle service intervals to prevent system downtime.

This part is specifically designed for precise fitment within the air brake system of high-capacity transit vehicles. Proper installation requires checking the through-drive alignment and ensuring all high-strength components are secured according to standard workshop procedures.
