Continuous bond

Our vents consist of a matching pair of welded frames sandwiching a 1” thick steel honeycomb matrix made from steel strips fused together with a thin layer of solder. This forms a continuous electrical and mechanical bond throughout the matrix. This product meets shielding effectiveness testing standards ITSG-02, IEEE-STD-299-2006, and NSA-65-6.

Additional features

  • Available in 3/16” with 10 GHz attenuation and 1/8” cell size with 40 GHz attenuation flange mounting allows for field location and installation into an existing room
  • Minimal air flow resistance and pressure drop
  • Continuously solder fused for superior strength and RF performance
