Genuine Cummins Onan Green Label air filter with foam pre-cleaner for older BF, BFA, BGA, BGAL, NH, NHL, and CCK RV generator series. Replace every 200 hours. 90-day limited warranty.
The Cummins Onan 140-0495 is the OEM-specified air filter for a range of older Onan RV generator series including BF, BFA, BGA, BGAL, NH, NHL, and CCK models. It is designed with a special foam pre-cleaner that provides an additional layer of filtration ahead of the main filter element — a feature not found in many aftermarket substitutes.
Cummins Onan notes that non-Green Label air filters may use lighter-density filter paper with sealing surfaces that become brittle and crack over time, allowing unfiltered air — and the abrasive particles it carries — directly into the engine intake. Even a small amount of dirt ingested over time is enough to cause accelerated piston ring and cylinder wear. Replace every 200 hours per the Cummins Onan maintenance schedule.
