Honeycomb Vent
In order to maintain the air flow inside the machine room, windows need to be opened on the shielding
shell, but the waveguide window must be installed to meet the response standard. The function of the
waveguide window is to ensure the air flow and prevent the leakage of electromagnetic signal. The ventilation
guide window is the main channel for shielding indoor air to exchange with the outside world, which can effectively
cut off the passage of electromagnetic wave.
Honeycomb Vent is a special but indispensable part of a MRI/ RF shielding room
and shieded cabinet. It is usually using for air pass. Its shielding range is ≤20GHz.

Ventilation guide window air inlet 300 * 300mm and equipped with air exchange device
(1) The shielding ventilation window is in the form of cut-off waveguide, and its insertion attenuation should be
consistent with that of the shielding chamber. The waveguide window is composed of many waveguides, and
the cross section of the small waveguide is hexagonal;
(2) The waveguide piece is made up of a new low temperature brazing process.
