Shielded Fan Ventilation Panels

MAJR offers EMI/RFI shielded fan ventilation panels in a variety of materials and 5 different sizes.

Shielded Fan Ventilation Panels

MAJR Products’ shielded fan ventilation products(shielded fan vents) are manufactured to meet the commercial market’s requirements for a low-cost, high-quality EMI fan vent panel. These small fan sized shielded waveguides are available in five standard sizes using a 0.250” thick honeycomb material and have an overall thickness with gasket of 0.407”. Standard gasket is a Monel wire embedded in a solid silicone with an optional gasket of a beryllium copper fingerstock. Tin plate (MIL-T-10727), nickel plate (MIL-C-26074A) or a RoHS compliant plating are available upon request.

Shielding effectiveness is in the 50-60 dB range at 1 GHz, depending on the gasket material used. Standard lead times for MAJR’s EMI fan vents is in the two- to three-week range for most sizes, with quicker deliveries available based on plating and quantities required.
