FaraVent™ EMI Vent Panels

Superior Shielding and Filtration Performance

The new FaraVent™ Honeycomb product provides superior shielding against electromagnetic interference and is specially designed for electronics, telecom, EV charging and military electronics equipment. The FaraVent™ Duoproduct pairs our highly effective EMI shielding media with Quadrafoam™ foam for protection from electromagnetic interference along with air filtration technology.

FaraVent™ Honeycomb Filters perform these distinct functions:

EMI/RFI shielding of 30-80 dB from 100 MHz to 40 GHz
Air straightening for maximum cooling efficiency.
When paired with Quadrafoam™ filter media, the product achieves high dust arrestance with low pressure drop.

The FaraVent™ EMI filter reduces EMI/RFI noise by using a honeycomb structure which provides “cells” that are designed to deflect and absorb EMI noise. The honeycomb pattern maintains minimal airflow impedance, and provides a “straightening” effect for even air distribution. In addition, an EMI shielding gasket is installed around the frame perimeter. The gasket ensures full conductivity of the frame to the equipment. Moreover, the filter is available with an EMI shielding stainless steel mesh for further EMI/RFI attenuation.

The FaraVent™ Honeycomb Filters also offer these benefits:

Performance specifications that meet the requirements of CE, Telcordia NEBS and UL.
Flame-retardant, open-cell polyurethane foam filter media for high dust arrestance.
Removable, cleanable and reusable.

Roll Channel: Roll formed into a strong sturdy one-piece channel using 3000 series aluminum. Frame is tightly fitted to filter media and fastened with an aluminum rivet. The UL listing, model number and air flow direction are roll imprinted into the frame. Part number is metal stamped into frame for quick, accurate identification.

Window Pane: In addition to the standard roll formed frame design, more custom options are also available. The windowpane air filter design allows for a customized, aluminum “frame-n-pane” design that integrates the frame and a series of crossing, reinforcing intermediates that provide media support.

Frameless: Faravent EMI honeycomb is configurable to be used without a frame using fabric-over-foam EMI gasket material to maximize air flow and shielding effectiveness.
