ISP offers a standard line of POREX® Virtek™ IP-rated PTFE vents for medical and scientific, electronics, and industrial applications.

Advantages of POREX® Virtek™ Vents

POREX Virtek™ PTFE Protection Vents used in sealed devices allow pressure equalization and ventilation due to temperature changes, and minimizes condensation while keeping dust, dirt, and liquid moisture out. 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, and vents for electronics and general 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, the vents are most often used in automotive lighting due to their ability to reduce moisture buildup and condensation
