High Performance EMI Shielded Vents | Brass, Steel & Stainless Steel Attenuated Vents

General Information

Our high performace EMI Shielded honeycomb ventilation panels are custom manufactured from steel, brass or stainless steel. When selecting the material, corrosion resistance relevant to the application environment should be considered along with the attenuation requirements.

Typical construction styles are shown in drawings VP 1 and VP 2 and other styles are available. Typical attenuation figures for the material types and thickness options are shown down the page. Both rectangular and circular styles are available. Various plating and gasket options are available and should be discussed at the time of ordering. High performance shielded EMC ventilation panels are manufactured to customer specification and a detailed drawing should be supplied.

Applications

High performance steel, stainless steel and brass vents are designed for demanding applications such as screened rooms, military applications and shelters where high attenuation is required across the frequency range and particularly in the H-field. This range of EMI shielded vents is especially suitable for EMP and TEMPEST applications.
