W. L. Gore & Associates, Inc. added its 3 mm-high airflow vent to its line of GORE Protective Vents. As the smallest protective vent in the line of insert-molded vents, the D3 vent relieves pressure that builds inside the housing. This vent prevents premature failure of the housing seals by virtually eliminating the vacuum, or by managing pressure fluctuations caused by pressure build-up. It provides continuous airflow in sealed housings without allowing contaminants to enter because of the proprietary expanded polytetrafluoroethylene (ePTFE) membrane in the vent. This membrane has a low surface tension so that it repels liquids such as water, oil and surfactants, as well as preventing dust, dirt and other environmental contaminants from entering the housing.
