Protection type
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
be absorbed through the door seal and can enter the enclosure.
The DA 284 Pressure Compensation Device provides a protected enclosure environment for
valuable and crucial components with a UL 4X rated degree of protection. A semipermeable
membrane inside the device allows air and humidity to leave the enclosure. In the opposite
direction, it only allows dry air into the enclosure while not allowing humidity and dust from the
outside to enter.

Installation
A hole with a diameter of 1.6 inches (40+0.5mm) is required for mounting. Make sure that the sealing gasket
is placed on the outer side of the enclosure. For optimal pressure compensation, it is recommended to use two
devices on opposite sides towards the top of the enclosure.
