Marine Crankcase Ventilation Filters & Separators

Prevent oily engine blow-by from accumulating in bilges and cabins with closed crankcase ventilation (CCV) systems from leading brands. Available at Fisheries Supply, our crankcase filters capture damaging hydrocarbons, preventing discharge into living spaces and overboard. We offer complete CCV filter kits from Racor and Sea Star featuring high-flow oil-separating elements. The filters connect via hoses to clean closed crankcase ventilation. Replaceable filter elements prevent replacing entire assemblies. CCV systems also reduce makeup oil consumption. Our marine engine specialists can help you select the optimal crankcase ventilation and separator setup. We'll match filters and mounting locations to your engine model for proper blow-by flow and drainage. Trust us for filter knowledge - whether meeting emissions regulations or simply keeping your boat clean. Stop oily buildup and maintain air quality with genuine Walker Airsep, Racor and other CCV systems from Fisheries Supply.
