EMI Ventilation panels from MAJR Products are ready-to-install EMI / RFI shielded panels in standard sizes made from brass, steel or aluminum for the electronics industry with minimum static pressure drop. Shielding effectiveness is accomplished using waveguide design principles – its 4:1 opening to depth ratio.


The choice of an EMI / RFI vent panel that best meets a specific design consideration is based on three main criteria: shielding, air flow, and mounting. MAJR’s EMI / RFI vent panels are supplied with an EMI / RFI gasket and mounting holes or captive fasteners to ensure easy installation.
