The CUMMINS 6.12" x 12" OD air oil separator is engineered for efficient separation of oil from the air, contributing to engine performance and reduced emissions. Its precision-engineered design safeguards engine components from excessive oil contamination. Its low-pressure drop enhances airflow, optimizing engine efficiency while maintaining performance under high-temperature conditions. Additionally, it provides reliable oil filtration, which supports engine longevity by minimizing wear and tear on components.
