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 mm thick honeycombs within a single frame. The shielding performance will improve as airflow is decreased, but not eliminated.

For military applications we make a heavy hot-dip galvanized mild-steel version. Please contact us for more information.

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

Benefits
  • Lightweight
  • 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
  • Kick plate for mechanical protection
  • Stainless steel, mild steel or brass versions
  • Cell sizes 1.6mm, 3.2mm, 6.4mm, 9.5mm, 12.7mm, or 19mm (standard 3.2mm)
  • Gaskets for firm connections Amucor shielding gasket or Knitted wire mesh gasket

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 an 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.

Honeycomb copper version

Optional on request is a copper version of the honeycombs available in 6.35 and 12.7 mm thickness.

Standard dimensions

Our Honeycomb ventilation panels are usually custom made for our client. However, some common dimensions are in stock. In the standard dimensions table below some common types of Honeycomb ventilation panels are specified to illustrate the required information. Hole diameter P is standard 3.5 mm, with other dimensions possible on request. Also available with screw apertures or inserts.
