FIELD: ventilation systems equipment.
SUBSTANCE: invention relates to the field of ventilation systems equipment, in particular to linear slot diffusers for concealed installation, built into the ceiling, made of gypsum board (GB) and a metal frame. The claimed effect is achieved due to the frame structure of the diffuser profiles, consisting of three segments containing a frame with voids and forming its outer and inner walls, while the inner part of the profile is formed by a surface having an obtuse angle, and the area of the space forming voids in each segment is larger the area of the frame of the corresponding segment.
EFFECT: invention increases reliability of the diffuser design, due to the frame geometry of the profile, which ensures the formation of a single rigid structure with a metal frame of GB ceilings after the diffuser is installed.
