Improve your system functionality with advanced filter media and vents

Porex manufactures a wide variety of filter and venting media for numerous drive system and other automotive applications.  Our advanced filter media and venting materials can help reduce emissions and make your product easier to assemble.

Our advanced materials include:

  • Advanced media – can efficiently separate oil mist from air streams or water from fuel/oil streams in a single component, self-supporting form. 
  • High performance POREX Virtek® PTFE – can be directly welded onto plastic enclosures and reservoirs providing a tough permanent vent.
  • Standard or customized general filter media – can be made into 2D or 3D forms that can replace multiple components.

Crankcase Ventilator (CCV)

Crankcase Ventilator (CCV) Filtration Media

Consistently high-performance fractional filtration efficiency filter media

Our customized direct formed bonded fiber filters offer a lower pressure drop with consistently high filtration efficiency that removes ≥96.4% of oil mist and particulates from engine blow-by gases. This not only maintains clean air recirculation into the intake manifold and oil into the crankcase oil sump but also reduces utilization of the by-pass system, further reducing NOx emissions. Porex CCV filter material performance not only helps engines meet global emission standards, its lower initial pressure drop, and oil repellency reduces filter saturation, maintaining lower a differential pressure which can extend filter and engine life.

Specifically designed to reduce vehicle emissions and to improve engine performance, our crankcase ventilator filters can be customized to fit most oil mist separation applications.

  • Our unique bonded fiber structure can efficiently separate over 95% of oil mist from oil reservoir blowby gases.
  • Consistently provides filtration efficiency that regardless of engine load delivers consistently high fractional filtration efficiency.
  • Reduces filter footprint, as POREX® filter media can perform the same or better than filter media in sizes up to 40% larger.

Oil & fuel water separation media for automotive engines

Fuel Water Separation Media

Greater efficiency high performance separation media

Our fuel water separation media feature a unique bonded fiber technology that can perform the function of multiple layers of traditional filter media, efficiently separating water from diesel and other fuels. With its gradient density structure, our reliable, efficient media protects fuel injections systems while improving engine performance and life.

Specifically designed to remove water from diesel other fuels to improve performance, our fuel water separation filters are available in a variety of customized sizes and configurations:

  • Our unique bonded fiber structure can efficiently separate over 97% of particulates and contaminates from fuel streams
  • Efficiently removes water from fuel streams that can cause issues with injectors and engines
  • Increase efficiency, as POREX® media can perform the function of multiple layers of traditional separation filter media

Electrolyte Reservoirs and Wicks

Fluid Reservoir Vents & Filters

Protect automotive fluid reservoirs

For automotive fluid reservoirs, manufacturers trust POREX hydrophobic and oleophobic PTFE vents and fiber media filters.

  • Feature robust POREX Virtek PTFE – Pure PTFE media is extremely hydrophobic. It features high temperature resistance and can be directly welded to caps or enclosures.
  • Can be customized – Self-supporting filter media can be customized into many shapes.
  • Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
