Honeycomb Vent
Honeycomb Vent is a special but indispensable part of a MRI/ RF shielding room and shielded cabinet. It is usually using for air pass. Its shielding range is ≤20GHz.
In common, we distinguish it from its material, thickness, cell
hole size, outer size, with or without frame. We have Stainless Steel, Tin plate, Brass, even Aluminum materials. Product Specification
Product features the cut-off waveguide ventilation window is composed of hexagonal honeycomb core material with frame. On the premise of ensuring efficient ventilation, the principle of high pass and low resistance of cut-off waveguide is used to effectively shield electromagnetic wave. Generally speaking, the cut-off principle of cut-off waveguide is: l ≥ 5D (L: waveguide length, D: maximum diameter of waveguide section), Therefore, the shielding effectiveness of the cut-off waveguide ventilation window depends on the length of the waveguide (i.e. the thickness of the honeycomb core and the size of the aperture of the honeycomb core)
