An air spout device for an air conditioning system comprises a duct having an intake portion and a ventilator spout. A plurality of guide vanes are arranged in the duct to define passages, and a plurality of dampers are arranged between the intake portion and the plurality of guide vanes to selectively open and close the passages, the plurality of dampers being rotatable with its shaft to assume concentration blow, diffusion blow, and avoidance blow modes. A blow mode selecting mechanism is operatively connected to the shaft to allow the plurality of dampers to assume the concentration blow, diffusion blow, and avoidance blow modes.
