Crankcase Ventilation Systems for Marine Engines


Prevent oily engine blow-by from accumulating in bilges and cabins with closed crankcase ventilation (CCV) systems from leading brands.like Walker Airsep, or Racor , available at Fisheries Supply. Our crankcase ventilation 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 crankcase vent filters connect via hoses to clean closed crankcase ventilation systems, ensuring optimal performance and environmental compliance.

Benefits of Closed Crankcase Ventilation Systems

  • Environmental Protection: CCV systems reduce an engine's crankcase harmful emissions from entering the atmosphere, protecting the environment, your crew, and your engine.
  • Reduced Oil Consumption: By capturing and recycling oil mist, CCV systems reduce the need for makeup oil, saving you money and maintenance time.
  • Enhanced Engine Performance: Proper ventilation reduces crankcase pressure, preventing oil leaks and improving engine efficiency.

Features of Our Crankcase Ventilation Filters

  • High-Efficiency Filtration: Our filters are designed to capture up to a high percentage of oil mist and particulates, ensuring clean air intake and optimal engine performance.
  • Replaceable Filter Elements: Instead of replacing entire assemblies, our crankcase filters feature replaceable elements, making maintenance easy and cost-effective.

Why Choose Fisheries Supply?

Our representatives know the latest technologies and regulations, ensuring you get the best solution. Whether you need a diesel engine crankcase breather or a complete closed crankcase ventilation system, we have the expertise to help you.
