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.
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 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.
