Mission Darkness™ Shielded Honeycomb Air Vent
Product Overview
The Mission Darkness™ Shielded Honeycomb Air Vent provides EMI/RF shielding while maintaining airflow through Faraday enclosures, screened rooms, electrical control panels and shielded cabinets. The steel honeycomb core blocks electromagnetic interference and is lab tested and certified to IEEE 299-2006 by Keystone Compliance Laboratory, with validated shielding effectiveness across 1.5 GHz to 40 GHz.
The vent ships with a pre-drilled mounting frame, threaded screws and wire-mesh gaskets — designed to mount directly into conductive materials such as TitanRF™ Faraday Fabric to preserve the shielding integrity of the enclosure.
Key Features

Installation
Mount the vent directly into conductive materials (such as a TitanRF™ Faraday Fabric panel) to preserve shielding integrity. The pre-drilled frame and included threaded screws and wire-mesh gaskets allow a clean RF-tight installation. For best results, pair with TitanRF™ Faraday Fabric and TitanRF™ Faraday Tape to seal all surrounding seams.
