Standard Honeycomb ventilation panels
9500 serie

Shielded vent panels for ventilation and heating

Honeycomb vents are used to shield openings for heating and ventilation against undesirable electromagnetic waves.

The honeycomb vent panels are supplied in rigid aluminium frames, pre-drilled or with fasteners made to your specifications or flow drilled thread holes.

Standard and cross-cell version

If a very high shielding level is required, the use of cross-cell honeycombs is recommended. These are made from two pieces of 6.35 mm or 12.7 mm thick honeycomb within a single frame. The shielding performance will improve at the expense of slightly increased air flow resistance.

  • The shielding effectiveness of the standard honeycomb ventilation panels is shown in the table below.

Shielding Performance

Frequency MHz Mode Attenuation dB
0.01 H-Field 45
0.1 H-Field 49
1.0 H-Field 51
1.0 E-Field >100
10.0 E-Field >100
100.0 E-Field >>100
1000.0 Plane Wave 98
10000.0 Plane Wave 95

In the table below some common types are specified to illustrate the required information. Hole diameter P is standard 3.5mm but it ca be delivered in any other size. Also available with screw apertures or inserts.
