The 28400.0-00 is a Pressure Compensation Device made of plastic. Pressure differentials in enclosures with a high degree of protection are a result of internal and external temperature changes. In the case of negative pressure or partial vacuum, dust and humidity can enter the enclosure through the door seal. When the air inside the enclosure cools down, condensation may occur because the humidity cannot escape the enclosure. The easy-to-install pressure compensation device DA 284 provides a slight overpressure, membrane inside the plug allows the humidity to escape whilst blocking water and dirt from entering the enclosure.
