  • High degree of protection
  • Waterproofmembrane
  • Easy to install

Pressure differentials in enclosures with a high degree of protection are a result ofinternal andexternal temperaturechanges. In the case of negative pressure or particalvacuum, dust and humidity can enter the enclosurethrough the door seal.When the air inside the enclosurecools down, condensation may occurbecause the humidity cannotescape the enclosure. The easy-to-install pressure compensation device DA 284 providescompensation of pressure at a protection degree of IP66 (M12: IP67).Evenwith aslight overpressure, a waterproof membrane inside the plugallowsthe humidityto escapewhilst blockingwater and dirt from entering the enclosure.
