A4571304815 MERCEDES BENZ O403 Twin Cylinder, Air Compressor

The heavy-duty twin cylinder air compressor is a critical component designed to maintain consistent pneumatic pressure within the vehicle's braking system. Featuring a robust construction with a swept volume of 636cm³, this unit ensures reliable operation under demanding conditions. The integration of a water-cooled valve plate and specialized ports optimizes thermal management and airflow efficiency for long-term durability.

A4571304815 is the OE-equivalent Twin Cylinder, Air Compressor used in the MERCEDES BENZ O403. This high-strength component is engineered to meet strict technical specifications, ensuring seamless integration with the original pneumatic architecture. It provides essential air compression functionality to support the braking systems of heavy commercial vehicles.

Workshop technicians should ensure that the water inlet and outlet ports (M16x1,5) and air ports (M26x1,5) are properly seated to prevent leaks. Given its water-cooled nature, maintaining the cooling circuit integrity is vital for preventing overheating. Regular inspection of the air unloader port and the through-drive mechanism is recommended during standard heavy commercial vehicle service intervals to ensure optimal performance.

This part is specifically engineered for precision fitment in heavy-duty applications where consistent air delivery is paramount. By utilizing high-strength components and precise machining, it maintains stable pressure levels throughout the compression cycle.
