Honeycomb fan shield

Honeycomb fan shield

Honeycomb ventilation grids specifically designed for standard sized fans in e.g. computer cases

A range of low-cost EMC vents for use with standard fan size fans. The Honeycomb fan shield 9530 series are designed to provide EMI shielding and maximum airflow without degrading the fan output. These vents provide a low-cost option to perforated metal when airflow rates are critical. A beautiful high-gloss acrylic frame is fitted with one layer of 6.35 or 12.7 thick honeycomb material and an optional Amucor conductive gasket to ground the honeycomb to the metalwork. Honeycomb Fan Shield in almost all sizes corresponding to industry-standard fans with standard 4-hole mounting.


Dust screen (on request)

Dust screens consisting of multilayer expanded aluminium can be added, but airflow will be restricted.

Shielding performance

Shielding performance is achieved from 1/8 cell aluminium honeycomb panels with compressed edges mounted in a square-shaped flat Mu- ferro plate with a circular cut-out on the inside. The contact with the housing is made with an amucor shielding gasket cut into the correct shape of the Honeycomb fan shield.

Performance below has been measured with honeycomb specifications 1/8 Cell size, 1/4 Thick.
