Cummins Onan Generator Air Filter - 140-1229



Genuine Cummins Onan Air Filter 140-1229

Onan Green Label air filters are designed with a special foam pre-cleaner, for use specifically in Cummins Onan RV Generators. Other manufacturers’ air filters may contain a lighter density filter paper and the sealing surfaces may get brittle and crack over time, allowing dirty air into the engine intake system. Over time, it only takes about a thimbleful of dirt to wear out piston rings and cylinders. Please refer to your Operator’s Manual for specific maintenance intervals.

Fits Onan Generator Models: NH Power Drawer (Spec A), NH Power Drawer 9000 (Spec A-H)
