DA 284 Vent Plug UL Type 1, 4, 4X & IP 66 protection Waterproof membrane Easy to install Two sizes - M40 & M12 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 through the door seal. The DA 284 Vent Plug provides a protected enclosure environment for valuable and crucial com- Photo: DA 284, M40 ponents with a UL 4X rated degree of protection. A waterproof membrane inside the device allows air and humidity to leave the enclosure. Conversely, it only allows dry air into the enclo- sure while not allowing humidity and dust from the outside to enter.
