PolyvenEx+New GORE® Polyvent Ex+

Safety & uncompromising performance for equipment in explosive atmospheres

Sealing Devices Inc proudly announces the launch of GORE® PolyVent Ex+. The latest addition to the Protective Vents Screw-In Series is certified according to explosion-proof safety standards, IECEx and ATEX. This will enable sales of products globally with fewer certification efforts, saving labor and testing costs. Plus, the PolyVent Ex+ offers additional protection performance due to its unique design.

GORE® PolyVent Ex+ has earned the IECEx and ATEX certification codes Ex II 2G Ex eb IIC Gb and Ex II 2D Ex tb IIIC Db. IECEx and ATEX directives describe general requirements for equipment, components and devices that are used in potentially explosive atmospheres. Therefore PolyVent Ex+ is allowed in areas with potentially explosive atmospheres caused by combustible gases or dust as following:

  • Gas: All non-mining, above-ground applications (equipment group 2) in the Zones 1 and 2 with need for protection type “eb” (increased safety) for Equipment Category 2 Gb.
  • Dust: All non-mining, above-ground applications (equipment group 2) in the Zones 21 and 22 with need for protection type “tb” (standard protection by housing) for Equipment Category 2 Db.
  • Uncompromising performance. All materials selected for designing GORE® PolyVent Ex+ have been chosen as they support the vent’s long-lasting exceptional behavior in the field. The vent body, cap and Gore’s creative, patented membrane-sealing technology only use premium 316L non-flammable, stainless steel.

This new product was developed to meet the needs of many of our customers who are working in industries that process, use or manufacture materials that may give rise to an explosive atmosphere. The new Ex-rated GORE® PolyVent Ex+ is the perfect fit for these tough environments.
