Air filter to suit 3.6 kVA Onan generator

Air Filters

Genuine Cummins Onan air filters are designed with a special foam pre-cleaner, for use specifically in RV generators. Other manufacturers’ air filters may contain a lighter-density filter paper and the sealing surfaces may get hard and crack over time, allowing dirty air into the engine intake system. Over time it takes about a thimbleful of dirt to wear out piston rings and cylinders. (Replacement filters for some older models may not include the pre-cleaner.)
