Honeycomb ventilation 9500
Shielded vent 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 at the expense of slightly increased air flow resistance.

Standard and cross-cell version:
(Cross-cell version for higher shielding performance)

Standard and cross-cell version

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

Standard delivery time: less than two weeks.
