The FLEETGUARD 11.73" oil air separator element captures and separates oil droplets efficiently, ensuring a cleaner air intake for engines. By preventing oil from contaminating intake air components, it reduces wear and tear, supporting proper engine operation. Engine performance is optimized by maintaining appropriate airflow and filtration, crucial for reliable engine function. Constructed to manage high oil mist loads, it extends service intervals and protects sensitive engine parts, promoting longer engine life and consistent reliability.
