W. L. Gore & Associates, Inc. has announced the Polyvent/M12 Protective Vent for equalizing pressure in telecommunications equipment exposed to severe weather conditions. Extreme temperature fluctuations cause strong pressure differentials inside the equipment housing and put stress on the housing’s seals. This stress can damage the seals, causing corrosion and leaking, ultimately resulting in equipment failure.

Available in both plastic and metal, the Polyvent/M12 vent allows air and gases to flow freely in and out of equipment housings, virtually eliminating the stress and damage on housing seals. At the same time, GORE Protective Vents shield the sensitive WiMAX electronics from harsh environmental contaminants, such as rain, snow, salt, and sand. The Polyvent/M12 high-airflow GORE Protective Vent is offered in plastic or metal. It provides water protection to meet IP66 for water jets, IP67 for 30 minutes of water submersion, and IP69K for high-pressure spray, ensuring the highest protection against water entry in any harsh environment.

For extremely rugged environments, the metal version of this vent is the best solution. Not only does the metal vent have an explosion rating approval, it can withstand temperature fluctuations from -40¬∞ to 125¬∞C. The Polvent/M12 vent meets hazardous substance thresholds specified in EU Directive 2002/95/EC (Restriction of Hazardous Substances or “RoHS”).
