Product description
Breather membranes GN 7404 are used in enclosure and device construction. In an enclosure wall, they ensure pressure compensation between the enclosure interior and the outside.
Any possible dirt and dust particles carried by the gaseous medium, but also oil and water drops, are retained. This protects the enclosure interior from contamination and moisture and also prevents e.g. oil from dripping into the surrounding area.
In order to protect the membranes, they should not be completely covered with oil or water, and the differential pressure / air outlet volume should not be exceeded. They should be installed on the side / vertically in a protected position.
The outer diameter of the enclosures with recessed hex is chosen to match screw-in holes for tube connections according to DIN 3852.
The seal is embedded in a radial groove and can therefore not be lost or squeezed out during the tightening operation.
Assembly note:
For wall thicknesses below 4 mm, use thin hex nuts GN 7430.
