EMC ventilation grill / honeycomb

Our VH Series of lightweight aluminium honeycomb attenuating ventilation panels comprise of forms of conductive airflow media retained within an aluminium extrusion. These EMC vents are designed for use in racks and other forms of commercial enclosure.
Applications

Our VH Series of EMC vents can be mounted onto most forms of shielded enclosure where airflow is needed, either over cooling fans or by convection. They can be mounted anywhere on the enclosure and can be fitted with protective 'kickplates' to protect the honeycomb material from accidental damage.

Where they may be exposed to the elements the vents can be fitted with 'slant' honeycomb which provides a downward facing aperture, preventing the ingress of rainwater. This has the added benefits of directional airflow and increased attenuation due to the higher aspect-ratio of the cell structure.
