Breather vent
Stahlin Non-Metallic Enclosures has introduced a new composite fiberglass Breather Vent. The vent 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. The company's vent is currently the only non-metallic vent carrying a UL type 4X rating. Typical applications include outdoor remote monitoring, electronics, indoor/outdoor chemical processing, gas monitoring, mass transit control systems, pump stations, waste water treatment systems, and units housing variable frequency drive systems.
