FIELD: equipment for ventilation systems.
SUBSTANCE: invention relates in particular to linear slot diffusers for distributing air flows built into a ceiling made of plasterboard (gypsum plasterboard) and a metal frame. In a preferred embodiment of the invention, a profile of a ventilation diffuser is claimed, made in the form of a single structure containing internal and external surfaces, wherein the internal surface has a rounded shape, and the external surface is formed by at least one hollow segment, and the rounding of the internal surface is continuous from the top to the bottom of the profile and the length of the rounded surface is more than 50% of the entire profile height.
EFFECT: reduction in noise during air distribution due to more efficient sliding of air flows along the inner surface of the profile.
