9500 series - Honeycomb ventilation panels

EMI shielded ventilation panels for ventilation and heating

Honeycomb vents are used to shield openings for ventilation or acoustic/visual contact. We can make these vents according to your drawing within a few days, or you can use our standard range from stock.

We can supply Honeycomb vents with frames, pre-drilled with fasteners or with flow-drilled thread holes. The standard material is aluminium which can be given a nickel finish (or any other finish you choose).

If high shielding levels are required, the use of cross-cell honeycombs is recommended. These are constructed from multiple sections of 6.35 mm or 12.7 mm or 26.3 mm thick honeycombs within a single frame. The shielding performance will improve as air flow is decreased, but not eliminated.

For military applications we make a heavy hot-dip galvanised mild-steel version; please contact us for more information.

Honeycombs are also frequently used as flow straighteners to create a laminar flow.

Benefits

  • Light weight
  • High shielding performance
  • Low air-flow resistance
  • Reduction of turbulence

Options

  • Cross-cell honeycomb for extra high shielding performance
  • Slant honeycomb 30°, 45°, 60° for outdoor rainproof applications
    45° degrees is the most common implementation. Please note, slant honeycombs are available on request.
  • Polyurethane filter for dust protection
  • Kickplate for mechanical protection
  • Stainless steel, mild steel or brass versions
  • Cell sizes 1.6 mm, 3.2 mm, 6.4 mm, 9.5 mm, 12.7 mm, or 19 mm (standard 3.2 mm)
  • Gaskets for firm connections

Approximately 95% of the honeycomb vents we produce are made to customer specifications.

Gasket material

Our 9500 series framed Honeycomb ventilation panels are generally supplied with a 6800 series Amucor gasket. This is a EMC gasket with an aluminum alloy. Suitable for most applications. However, due to galvanic corrosion for some applications, the Honeycombs can also be supplied with a 1200 series Metal knit gasket.
