GN7403 Breather Strainer, Aluminium with Stainless Steel Mesh
Breather strainers GN 7403 are used in enclosure and device construction. Once inserted into the wall of the enclosure, they ensure pressure equilibrium between the inside of the enclosure and the outside.
Any dirt and dust particles carried by the medium (usually gas) are prevented from exiting depending on the mesh size. This protects the insides of sensitive devices and machinery parts from dirt and pollution and also protects the environment from any exiting dust.
The outside diameter of the enclosure with the recessed hexagon matches the bolt mounting holes for DIN3852 threaded pipe connectors.
The sealing ring is embedded in a radial and plane-sided recess which makes the seal captive and prevents it from being squeezed out during tightening.
For mounting on walls of less than 4 mm thickness, please use mounting nut GN543.1.
