The CUMMINS 13" x 11.76" OD air oil separator is designed to effectively separate air and oil, reducing engine contamination. It efficiently minimizes oil consumption by capturing excess oil vapor, thus maintaining optimal engine performance through cleaner airflow. Additionally, it reduces maintenance downtime by enhancing the longevity of engine components. It also improves engine reliability by preventing oil residue buildup in the air intake, ensuring sustained performance and operational integrity over time.
