Plymouth, MA….Tech-Etch manufactures EMI Shielded Quiet Vents from prototype to high volume requirements. In-house plating improves shielding effectiveness and environmental protection, while providing fast turnaround. 8300 Series Quiet Vents are designed to provide high EMI shielding ratings of up to 90 dB attenuation. Shielding performance is achieved from two ¼-inch thick honeycomb panels assembled in a cross cell configuration. Since the honeycomb design yields 97% open vent area, unrestricted airflow results in reduced turbulance plus lower noise levels than vents constructed from perforated metal. Many RoHS compliant finishes are available. Offered in 66 standard sizes, Quiet Vents are a low-cost shielding solution for the cooling requirements of today’s electronic equipment. Light weight, aluminum frames come standard with a Twinseal gasket for shielding between the frame and the mounting surface. Twinseal gaskets provide an efficient environmental seal in addition to the EMI shielding from the attached mesh gasket. Quiet Vents are available with captive fasteners or through holes.
