Honeycomb Vent
The honeycomb vent is composed of a hexagonal metal waveguide matrix, using vacuum needle welding technology,
the waveguide matrix needs a certain length, i.e. the waveguide window has a certain thickness, relying on electromagnetic waves in the wave
The waveguide matrix needs a certain length, i.e., the waveguide window has a certain thickness, relying on the
multiple reflections of electromagnetic waves in the waveguide body to ensure that the electromagnetic wave attenuation
meets the requirements, while ensuring good indoor ventilation.

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)
Honeycomb vent are shielded from electromagnetic waves by using the principle of waveguide high-pass filtering, i.e., the waveguide passes electromagnetic waves above the cutoff frequency and attenuates electric 3.0T magnetic waves below the cutoff frequency, and the attenuation (shielding effectiveness) is proportional to the length of the waveguide.
Shielding room ventilation system uses shielding room special ventilation waveguide window, through the reasonable planning and design of the waveguide window, facilitate the arrangement of the outside ventilation pipe, to meet the internal ventilation, heat dissipation and sound requirements.
