The CUMMINS air oil separator measures 20.38 " by 14.25 " in outer diameter and is designed to effectively remove oil vapor, resulting in cleaner engine output. It enhances engine performance by minimizing oil carryover, contributing to improved overall engine health by reducing contamination. This component requires low maintenance due to its efficient separation technology. Additionally, it reduces wear and tear on engine components by limiting oil residues, ensuring the engine remains in optimal condition through its precise operation.
