Honeycomb Quiet Shield
Honeycomb vents & Filters

  • Honeycomb
  • The Honeycomb Quiet Shield are designed to provide high EMI shielding performance of up to 92 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.

    See picture for cross cell axample...


    The panels are mounted in high strength extruded aluminum frames with optional captive fasteners or thru holes as detailed below.

    Frame to enclosure shielding comes from Twinseal.
