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…
