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 12,7 mm thick honeycomb within a single frame. The shielding performance will improve at the expense of slightly increased air flow resistance.
