Ventilation waveguide windowThe shielding room ventilation system employs a specialized ventilation waveguide window, with its insertion loss corresponding to the shielding room's technical specifications. It consists of a waveguide bundle made up of numerous small waveguides, with the cross-sectional shape designed as hexagonal. Under the same insertion loss capacity, the hexagonal waveguide has a larger passage area than the square waveguide, thereby increasing the ventilation area and reducing the air exchange resistance.

The ventilation of the shielding room is achieved through an exhaust fan and a cutoff waveguide window. Pre-drilled holes are provided in the predetermined locations of the shielding shell for installing the ventilation cutoff waveguide window, which is welded to the shell. A flanged decorative frame compatible with the exhaust fan is also made, and decorative aluminum louver windows are used at the indoor air outlet.
