Structural Characteristics
● Cross-section forms typically include the following: circular,square, and hexagonal.
● Common specifications for hexagonal honeycomb ventilation waveguide windows are 10mm, 5.6mm, 4.76mm, 3.2mm(diameter of the inscribed circle of the hexagonal waveguidehole).
● Common sizes include: 300*300mm, 300*600mm,600*600mm; special sizes can be customized.
Main Functions
● Used for indoor natural ventilation, fresh air intake, airconditioning supply/retum air openings, fire smokeexhaust, pressure relief openings, etc.
Operating Principle
● A waveguide window is a waveguide bundle composed ofmany small waveguides. Under ventilation conditions,electromagnetic wave energy is gradually attenuated throughabsorption and reflection as it traverses the waveguides.
● It shields electromagnetic waves based on the high-passfiltering principle of waveguides. That is, waveguides allow electromagnetic waves above the cutoff frequency to passwhile attenuating those below the cutoff frequency. Theattenuation (shielding effectiveness) is proportional to thelength of the waveguide.
Performance Features
● Low air resistance coefficient, large effective ventilationarea, easy installation, and convenient connection to airducts.
● The inner surface of the waveguide window vent isnickel-plated and then painted to prevent rust.
● Shielding performance meets national confidentiality andmilitary standard-related standards; shielding effectivenessis consistent with the overall effectiveness of the shielded room.
