Protective venting for potentially explosive atmospheres

The PolyVent Ex+ (photo) is the newest addition to this company’s line of screw-in protective venting. It has been certified to explosion-proof safety standards of IECEx and ATEX. The vents’ rigorous certifications enable installation in areas with potentially explosive atmospheres caused by combustible gases or dust. The vent body and cap, as well as the patented membrane-sealing system, are constructed of 316L stainless steel. The membrane is made from ePTFE and provides stable pressure equalization, along with long-lasting oleophobic and hydrophobic protection. The membrane is rated for an airflow rate of 1,600 mL/min at 70 mbars. A silicone O-ring with a high flammability-resistance rating adds another layer of safety. — W.L. Gore & Associates, Newark, Del.
