enclosure ventilation plug PG29 pressure compensation fitting IP55 RAL7035 - PU: 2 pieces

The higher the degree of protection of housings, the greater the risk of condensation forming due to temperature fluctuations.
Due to temperature fluctuations, the pressure conditions change and moist ambient air gets into the housing due to negative pressure.
The moist ambient air then condenses on the (cold) housing wall and "condensation water" can form in the housing.
Pressure equalization fittings compensate for changes in pressure while maintaining a high degree of protection and preventing the ingress of dust and humidity.
The pressure compensation fittings are suitable for use in cabinets and housings.

¹ If the DAE is not installed vertically, the degree of protection is reduced to IP44.

assembly Instructions
Drill an air opening Ø 37⁺¹ mm in the housing wall and fasten the pressure compensation screw connection with a nut. Make sure that the sealing ring is on the outer housing wall. In order to ensure optimal pressure equalization, it is recommended to attach two pressure equalization screw connections diagonally opposite one another.
So one screw connection at the bottom left, the other at the top right.
