Pressure differentials in a hermetically sealed enclosure are a result of the heat generated by electrical and
electronic components in the enclosure, as well as the fluctuation of the outside temperature. In the case of nega­tive pressure or vacuum, for example, dust and humidity can enter the enclosure trough the door seal.The DA 284
Vent Plug provides a protected enclosure environment for valuable and crucial components with a UL 4X rated
degree of protection. A waterproof membrane inside the device allows air and humidity to leave the enclosure
while not allowing moisture and dust from the outside to enter.
