12.5MM EMI Honeycomb Air Vents Filter Stainless Steel Honeycomb Ventilation Panels
EMI RFI shield ventilation air filter for mri rf shielding stainless steel material
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 6.35 mm or 12.7 mm or 26.3 mm thick honeycombs within a single frame. The shielding performance will improve as airflow is decreased, but not eliminated.
Features for honeycomb vent window for shielding room
1- Provide maximum RF attenuation while allowing optimum airflow.
2- Available to suit individual requirements
3- Soldering waveguide windows use imported tin-plating to press molding, to ensure the quality while transport and assembly process and guarantee the shielding effect.
4- Produce various customized specification for civil or military use
