Page 1630 | 3.5 Controlling, Venting, Sealing of Liquids and Gases GN 7403 Breather Strainers Aluminum / Stainless Steel with Stainless Steel Mesh 1 Material 2 d 1 3 Mesh size How to order 1 2 3 GN7403-AL-G1-500 Breather strainers GN 7403 are used in enclosure and device construc- tion. Inserted into the wall of the enclosure, they ensure pressure equilib- rium between the inside of the enclosure and the outside. Any dirt and dust particles carried by the medium (usually gas) are pre- vented 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 mat- ches the bolt mounting holes for DIN 3852 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. Assembly instruction: For mounting on walls of less than 4 mm thickness please use mounting nuts GN 7430.
