Each booth is equipped with a double effect composite filter, which is made of nano multifunctional primary filter layer + HEPA + composite carbon attached layer, effectively filtering PM 2.5, formaldehyde, toluene, TVOC and other pollutants.
The interiors are composed of polyester fiberboard with sound absorbtion, environmental protection, flame retardancy, decoration and easy processing. The thickness of the conventional sound absorbing board is 9 mm, and the thickness can be adjusted according to the needs of noise reduction.
The glass of each soundproof room is assembled from 10 mm thick single layer tempered glass certified by 3 C. In order to increase the safety, engineers put explosion proof film on each glass.
In order to facilitate the movement, each soundproof room is equipped with steel universal wheel, which can steer freely without pressure. At the same time, a steel foot cup is arranged next to each wheel to prevent the soundproof room from moving when it is stationary. (Except for the smallest one.)
