The CUMMINS 13.70" x 11.81" OD air oil separator is engineered to effectively separate oil, preventing engine contamination and thereby extending engine life. Its large surface area is optimized for airflow, contributing to improved engine performance. By reducing exhaust emissions, it supports a cleaner environment. It minimizes oil consumption through the efficient recycling of trapped oil. Additionally, its sealed design prevents oil leaks, helping to maintain a clean engine bay.
