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
