Vents & Filters Quiet Vents Series 8300

The 8300 Series Quiet Vents are designed to provide high EMI shielding performance of up to 90 dB attenuation with very low costs. These vents are offered as an alternative to perforated metal or slots to reduce turbulence and noise by providing an unrestricted and quiet airflow. Shielding performance is achieved from two 1/4 inch thick honeycomb panels assembled in a cross cell configuration. The panels are mounted in high strength extruded aluminum frames with optional threaded inserts or thru holes as detailed below. Frame to enclosure shielding comes from Twinseal.
