DA 284氣密裝置
高度保護
易於安裝
1、 該裝置為電氣配電櫃，提供一個安全的有氣密保護性的分環境。
2、 密閉的箱子中，因為晝夜交替時溫度的變化而引起箱內氣壓變化。
3、 避免灰塵及濕氣的吸入。
4、 DA084氣壓密裝置允許氣壓在允許的范圍內發生變化。
5、 因為氣密裝置有IP45高度保護能力，所以當我們把它安裝在任何箱子裡，都不會影響箱體的功能。

Pressure compensation Device DA 284
High degree of protection
Waterproof membrane
Easy to install
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 partical 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 compensation of pressure at a protection degree ofIP66. Even with a slight overpressure, a waterproof membrane inside the plug allows the humidity to escape whilst blocking water and dirt from entering the enclosure.
