9500 series - Honeycomb ventilation panels

EMI shielded ventilation panels for ventilation and heating

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

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

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 slightly at the expense of  increased air flow resistance.

Honeycomb material thicknesses

We manufacture honeycomb core material in 6.35, 12.7 and 26.3 mm thickness.


Benefits

  • Light weight
  • High shielding performance
  • Very 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
  • Polyurethane filter for dust protection
  • Mechanical protection against damage
  • Stainless steel version or brass version
  • Cell size 1.6 mm, 3.2 mm, 6.4 mm, 9.5 mm, 12.7 mm or 19 mm (Standard 3.2 mm

Approximately 95% of the honeycomb vents are made to customer specifications and are made to comply an order.
