Description

The Cummins Onan A030Y328 is a genuine Green Label air filter with a foam pre-cleaner. It is the OEM-specified air filter for the HGJBB RV QG 2500 and QG 2800 LP (propane) generator series, Spec A–B.

The filter features a special foam pre-cleaner for an additional stage of filtration, capturing larger airborne particles before they reach the main paper element. This design helps prevent unfiltered air from entering the engine intake, which can accelerate wear.
