GN 7403 Breather Strainers Aluminum, with Stainless Steel Mesh


Product description


GN 7403 breather strainers are used in enclosure and device construction. Mounted into the wall of the enclosure, they ensure pressure equilibrium between the inside of the enclosure and the outside.

The outside diameter of the enclosure with the recessed hexagon matches the bolt mounting holes for DIN 3852 threaded pipe connectors.

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.

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.
