Honeycomb Ventilation Panels
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 6.35mm or 12.7mm or 26.3mm thick honeycombs within a single frame. The shielding performance will improve as air flow 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.
