Honeycomb Ventilation

Shielded vent panels for ventilation and heating

Honeycomb Vent Panels

Honeycomb vents are used to shield openings for heating and ventilation against undesirable electro-magnetic waves. 

The aluminium honeycomb vent panels are supplied in rigid aluminium frames, pre-drilled or with captive fasteners 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 12,7mm thick honeycomb within a single frame. The shielding performance will improve at the expense of slightly increased air flow resistance. 

Honeycomb Vent Panels

Approximately 95% of the honeycomb vents are made to customer specifications, and are all made to order. 

Standard delivery time: less than two weeks.

 

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 (high volume only) 
  • polyurethane filter for dust protection 
  • mechanical protection against damage 
  • stainless steel version 
  • brass
