Advantages of Porex Virtek® Vents

Used in sealed devices, Porex Virtek® PTFE protection vents allow pressure equalization and ventilation due to temperature changes. They also minimize condensation while keeping out dust, dirt, and liquid moisture. Porex Virtek® sintered PTFE membrane is UL 94 V-0 and UL 746C listed, tested to meet all IP ratings, and can meet NEMA or other test standards.

  • Robust sintered porous structure (safe to handle)
  • Minimizes condensation and prevents the entry of dust, dirt, water and other contaminants
  • Porex® vents are UV and weather resistant, chemically inert, thermally resistant, UL-listed
  • Omni-directional flow
  • Standard data sheet

Applications for Porex Virtek® Vents

  • Electronic applications: The vents are designed to have low acoustic loss, with applications including wind screens for microphones, as well as vents for electronics and sound dampening components.
  • Medical applications: Arterial syringe vents that help to eliminate blood bypass, and self-sealing IV catheter vents.
  • Automotive applications: Ranging from batteries and motors, to fuel filters and gas caps, Porex Virtek® vents are most often used in automotive lighting due to their ability to reduce moisture buildup and condensation
