Champion 300KCA035 Air Oil Separator Element For Heavy Duty Engines

300KCA035 Champion air/oil separator element is a spin-on replacement filter for Champion heavy‑duty engine air/oil separator systems, designed to replace the original separator element in Champion L‑Series equipment. Marketed as an OEM‑equivalent replacement, it matches the form factor and filtration role of the factory part to maintain oil separation performance. In catalogs and cross‑reference listings, 300KCA035 is associated with Champion L‑Series models in the 15–22 range (Walker‑branded variant 300KCA035‑W is noted for L‑Series 15-22). Some catalogs list related replacements such as 300KBA035 for other L‑Series configurations, illustrating the part family’s interchange. This element is intended to be installed inside the separator housing as part of routine maintenance to restore separation efficiency and minimize oil carryover in heavy‑duty engine air systems. Used by service technicians when replacing worn separator elements, it supports continued operation of the engine’s air/oil separation stage and helps protect downstream components from oil contamination.
