    The invention relates to ventilation and relates to air distributors.
    A known air distributor, comprising an inlet nozzle and blades located between the last and guiding disk, is curved relative to the axis of the inlet nozzle l.
    However, said air distributor does not ensure sufficient uniformity of the distribution of the inlet flow and a decrease in its speed.
    The aim of the invention is to increase the uniformity of the distribution of the inlet flow and reduce its speed.
    This goal is achieved by the fact that in the air distributor containing the inlet nozzle and the blades located with the last and guiding disk, bent relative to the axis of the inlet nozzle, the angle between the perpendicular to the plane tangential to the blade surface at any point of the output edge and the perpendicular to the plane this point on the axis of symmetry, less than 85 .823352
    The drawing shows nps.jyiaraema air distributor.
    The air distributor contains inlet pipe 1 and blades 3 located 5 between the last and directional disk 2, curved relative to the O-Q axis of the inlet pipe 1. Angle about between perpendicular b to plane D,. tangent to
    10 the surface of the blade 3 at any point of the output edge 4, and perpendicular to the CE, lowered from this point to the axis of symmetry aa, is smaller. The air stream leaving the inlet 15 of the nozzle 1, hits the guide disk 2, gets a radial direction and at the same time is twisted by blades 3. At the same time the air stream evenly spreads indoors, and
    speed in a short period of time is reduced to the desired value. Thus, such an implementation of the air distributor allows
    25 create radial expanding
    a stream of air that is intensively mixed with the room air in the vicinity of the air distributor and already for a short period
    30 times significantly reduces its speed.
