1100 120 003 Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable air pressure within the pneumatic braking system of heavy commercial vehicles. Designed with high-strength components, the unit ensures consistent functionality under demanding operational conditions. The water-cooled design and precision-engineered ports allow for optimal thermal management and air flow regulation.

1100 120 003 is the OE equivalent of the MERCEDES BENZ 447 130 05 15 and 447 130 37 15 air compressor used in MERCEDES BENZ heavy commercial vehicles. This component is specifically built to meet the technical requirements of the original equipment, ensuring seamless integration with existing engine and braking systems.

For workshop technicians, this part features a single cylinder with a Ø90.00 mm bore and a 46 mm stroke. It utilizes an M26x1,5 air inlet and outlet configuration, along with M22x1,5 water ports to maintain stable operating temperatures. Proper inspection of the water-cooled valve plate and connection seals is recommended during every service interval to ensure long-term reliability.

The assembly is designed for high-duty cycles in the heavy commercial vehicle sector, providing essential pneumatic support for braking and suspension systems. Regular maintenance of the cooling ports and monitoring the air output stability will help prevent system downtime.
