Genuine Cummins Onan Green Label air filter with foam pre-cleaner for Camp Power QG RM KVD and MicroLite KV/KVC RV generators. Fits QG 2500, 2800, 3000 LP, and 4000 models. Replace every 150 hours. 90-day limited warranty.
The Cummins Onan 140-2105 is the OEM-specified air filter for the Camp Power QG RM KVD and MicroLite KV and KVC RV generator series, spanning QG 2500, 2800, 3000 LP, and 4000 watt models. Like all Green Label air filters, it includes a special foam pre-cleaner that provides an additional stage of filtration ahead of the main filter element — a feature not common in aftermarket substitutes.
Cummins Onan notes that non-Green Label filters may use lighter-density filter paper with sealing surfaces that become brittle and crack over time, allowing unfiltered air directly into the engine intake. Even a small amount of ingested dirt is enough to cause accelerated piston ring and cylinder wear. Replace every 150 hours — sooner if the generator operates in dusty conditions or if engine performance deteriorates.

Always confirm using your generator's complete model number and spec letter before ordering — refer to the compatibility table below. If the generator operates in a dusty environment or engine performance has deteriorated, replace the filter sooner than the 150-hour scheduled interval. Refer to your Cummins Onan Operator's Manual or the Green Label Parts Reference Guide to verify the correct part for your specific unit.
