Breather vent, designed for use with company's non-metallic enclosures, allows the enclosure to "breathe" - allowing the free passage of air, thus equalizing the pressure differential between the enclosure and ambient before it builds to the point where a leak path is developed. Breather vent carries a UL type 4X rating. Applications include industrial power distribution, industrial machine tools, laboratories, outdoor remote monitoring, electronics, indoor/outdoor chemical processing, gas monitoring and more.
