Shielded HVAC Panel Design Guide For RFI And EMI Engineers
We’re getting a lot of questions about RFI and EMI attenuation, static pressure, and airflow in HVAC air ducts that penetrate secure buildings and SCIF enclosures. Enclosures, whether they’re built for human use or sensitive electronic equipment, require openings for conditioned air to enter the space for temperature control, ventilation, or both. As we pointed…
Read MoreMaking Knitted Wire Mesh – Superior EMI Attenuation + Flexibility for RFI / EMI Shielding
Knitted wire mesh is composed of wires woven into a fabric-type material resembling a tube. From the mesh, MAJR Products creates wire mesh tape, RFI / EMI wire mesh washers, EMR / RFI gaskets and more. This engineering and production process creates flexibility in many signal attenuation and hardened enclosure applications.
