Ventilations panels

Often used for electromagnetically screening ventilation opening, ventilation panels allow the free
movement of air while ensuring a high level of EMF/RFI protection.
GETELEC ventilation panels comprise a honeycomb filter element and a frame giving the structure
its rigidity.
These filters can be made in Surtec treated aluminum for applications where field H performance
is not too high or in tinned steel when good field H and Field E attenuation is required.

Electrical continuity between the ventilation panel and the housing is ensured by means of
a conductive elastomer seal or metal braiding. These filters are made to customer plans and
specifications.
