Brass & Steel Vent Panels

Brass and steel honeycomb vent panels are recommended when structural integrity, H-Field shielding effectiveness, harsh environmental conditions and durability are primary concerns. Brass or steel extrusions are customized to surround brass or steel honeycomb and welded in place. Continuous flow soldering provides enhanced contact between the honeycomb and frame improving integrity. Multi-Gasket, a combination of neoprene sponge and monel mesh fit, most applications although Wire-Knit or conductive gaskets are available. Standard through holes and spacing for surface mounting installation is customized. Vents without gasketing can be welded in place. Brass vents are typically finished with tin lead plating. Steel vents are commonly finished with tin plating. Other plating options available. Ideal for mobile military transportation, communication shelters or equipment where EMP or TEMPEST is required.
