How to shield ventilation openings against electromagnetic interference

Below we give a brief explanation of how you can shield ventilation openings and which products are suitable.

In electronics housings or shielded rooms it is usually necessary to cool, heat or refresh the air. However, one cannot simply create an opening for airflow, since that would almost completely destroy the proper electromagnetic shielding performance of the housing or room.

For electromagnetic shielding of air openings we have developed shielded air ventilation panels, grouped into several product variations (see products below). Shielded air ventilation panels, also called shielded honeycomb vent panels, provide adequate air flow for cooling or heating purposes in electronic enclosures or Faraday cages while preserving the necessary EMI shielding.

We have a comprehensive range of EMC or EMI vent panels and filters available that are all primarily designed to allow unrestricted airflow whilst preventing the transmission of electromagnetic interference (EMI). These products are used wherever there is a requirement for air cooling or ventilation without compromising the shielding integrity of an enclosure.
