FIELD: ventilation systems. SUBSTANCE: air distributor has cylindrical inlet branch, longitudinally expanding chutes hinged to its outlet end and provided with position retainers; corrugated spacers made of flexible material and attached at their ends to ends of branch and chutes. The latter are mounted for turning relative to inner surface of branch beyond direct impact of input jet. Top edges of each chute mount opposing noses whose loose ends carry hinged guide shields each provided with respective operating mechanism. Loose ends of shields face outlet end of branch and are disposed beyond direct impact of input jet. Adequate conditions are ensured to maintain desired pressure gradient on opposite ends of curved jet due to formation of closed-circuit circulating areas.
