DA 284 Pressure Compensation Device
High degree of protection
Waterproof membrane
Easy to install
Pressure differentials in encIosures with a high degree of Protection are a result of internal andexternal temperature changes. In the case of negative pressure or partical vacuum. Dust andhumiditv can enter the enclosure throuqh the door seaI．When the air inside the enclosure cools down, condensation may occur because the humiditv cannot escape the enclosure. The easy-toinstalIpressure compensation device DA 284 Provides compensation of Pressure at a Protectiondegree of IP66. Even with a sIight overpressure. a waterproof membrane inside the Plug aIIowsthe humidity to escape whilst bIocking water and dirt from entering the enclosure．
