What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, generating the compressed air necessary for brake operation and auxiliary pneumatic functions. Built with high-strength components, it is specifically engineered to withstand the demanding thermal and pressure cycles found in modern diesel engines.

Vehicle and engine compatibility

This unit is compatible with Mercedes-Benz ATEGO 3 models, including variants such as the 1216, 1218, 1221, and 1223 series, specifically those equipped with the OM 934 LA engine.
