9530 series - 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 air flow 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. The vents have 4 countersunk holes to suit standard fan mounting.
Holland Shielding Systems B.V. stocks Honeycomb Fan Shield in almost all sizes corresponding to industry standard fans with standard 4-hole mounting (See table below for the standard sizes).
Shielding performance is achieved from 1/8 cell aluminum honeycomb panels with compressed 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 have been measured with honeycomb specifications 1/8 Cell size, 1/4 Thick.
Dust screen (on request)
Dust screens consisting of multilayer expanded aluminum can be added, but airflow will be restricted.
