Product description

Breather strainers GN 7403 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 medium, usually gas, are prevented from being exchanged, depending on the mesh size. This protects the inside of the device from contamination and also protects the environment from any exiting dust.

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.
