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) Filtration Media
Consistently high-performance fractional filtration efficiency filter media
Powertrain Vents and Filters
Minimize emissions with powertrain vents and filters
Fuel Water Separation Media
Greater efficiency high performance separation media
Fluid Reservoir Vents & Filters
Protect automotive fluid reservoirs
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.
