MAJR’s fan ventilation panels are manufactured to meet the commercial market’s requirements for a low-cost, high-quality EMI-shielded ventilation panel. These units 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 available upon request.
Shielding effectiveness is in the 50-60 dB range at 1 GHz, depending on the gasket material used. Standard lead times are in the two-to-three week range for most sizes with quicker deliveries available based on plating and quantities required.
