Aluminium honeycomb fan shield with threaded holes 9535
Honeycomb fan shield ventilation panel with threaded holes for easy installation in e.g. computer cases to provide EMI shielding and maximum airflow without degrading the fan output.
A range of low-cost EMC vents for use with standard fan size fans. The aluminium honeycomb fan shield 9535 series is 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. An aluminium frame is fitted with one layer of 6,35 or 12,7 mm thick honeycomb material and an optional Amucor conductive gasket to ground the honeycomb to the metalwork. The vents have 4 countersunk holes to suit standard fan mounting.
Holland Shielding Systems B.V. stocks aluminium Honeycomb Fan Shield in almost all sizes corresponding to industry-standard fans with standard 4-hole mounting (See table below for the standard sizes).
Dust screen (on request)
Dust screens consisting of multilayer expanded aluminium can be added, but airflow will be restricted.
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.
In the table below some common types are specified to illustrate the required information. Drillhole diameter is standard 3.5 mm but it can also be delivered in any other size. Also available with screw apertures or inserts on request.
