PRESSURE COMPENSATION DEVICE (STAINLESS STEEL)

Enclosure Accessory, Vent Plug, Enclosures & Electrical Cabinets

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 Sinohua code DA284 provides compensation of 
pressure at a protection degree of IP66. 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.

Product Overview
The 284 element from Sinohua is a Stainless Steel Vent Plug provides a protected enclosure environment for valuable and crucial components with an IP66 rated degree of protection. A water-proof membrane inside the device allows air and humidity to leave the enclosure while not allowing moisture and dust from the outside to enter. It is suitable for hermetically sealed enclosures.
