Tech-Etch, Inc. introduced EMI shielded honeycomb vents, fan vents, quiet vents and air filters in all shapes and sizes. Honeycomb vents are offered in both standard and custom configurations. Nine different aluminum vent styles are offered, and additional shielding gaskets can be added to increase attenuation. Shielded fan vents with optional dust screens provide maximum airflow without degrading fan output. Quiet vents with honeycomb media provide maximum air flow through openings requiring shielding to 90 db attenuation levels. Quiet vents offer low-cost shielding for the cooling requirements of electronic equipment. Shielded filter and dust shields attenuate EMI and provide a passage for cooling air while filtering dust.
