In conditions where there are temperature fluctuations and moisture, the metallic Ex e breathers from the 781 series protect electrical wiring from the effects of condensation inside the enclosure. They provide continuous pressure equalisation between the inside of the enclosure and the atmos-phere around the enclosure. There are two metric and two NPT thread versions available for this purpose. An integrated connection thread seal and a special fixture nut are included in the stand-ard version. They have worldwide certification according to IECEx, ATEX and cCSAus.
