Metal ventilation grill 8200 Series

EMChoneycomb

The 8200 Series of Shielded Fan Vents are designed to provide EMI shielding and maximum air flow without degrading the fan output. These vents provide a low cost option to perforated metal when airflow rates are critical. Tech-Etch stocks fan vents in 5 sizes corresponding to industry standard fans with standard 4-hole mounting. Shielding performance is achieved from 1/8 cell aluminum honeycomb panels mounted in high strength extruded aluminum frames with beryllium copper shielding strips for shielding the frame to the enclosure. Dust screens consisting of multilayer expanded aluminum can be added, but airflow will be restricted.
