The present invention relates to an air nozzle which directs the air conditioned in the air conditioning systems used in the vehicles into the cabin, comprising at least one straight air direction valve which controls the speed of the upper air flow blown towards the bodies of the driver and the passengers, at least one direction changing valve which controls the speed of the lower air flow changing the flow direction of the upper air blown towards the bodies of the driver and the passengers, at least one upper acceleration nozzle (2) through which the upper air flow passes and is accelerated before being blown into the cabin, at least one lower acceleration nozzle (3) through which the lower air flow passes and is accelerated before being blown into the cabin, upper coanda surface (4) which enables the air inside the vehicle to be sucked and blown by the upper air flow by means of the coanda effect, lower coanda surface (5) which the lower air flow follows by means of the coanda effect, and which enables the upper air flow to be sucked and change direction towards down by creating vacuum by the lower air flow.
