An air guide box, in particular for a heating, air conditioning and/or ventilating installation in a motor vehicle, comprising at least an air treating device (10, 12), at least an air channel (20) extending through the air treating device (10, 12), and at least an air channel (30) bypassing the air treating device (10, 12) and at least two outlet channels (40, 50), emerging in a gap (3) such that each time an outlet channel (40, 50) is substantially opposite one of the other channels (20, 30), a device (1) mobile about an axis (2) being arranged in the gap (3), which device has an air guiding element in the form of a channel (4, 5, 6, 7) and provides, in specific positions, an air passage with practically no pressure drops between two mutually opposite channels (20, 40; 30, 50), and an air passage subjected to pressure drops between other opposite channels (30, 50; 20, 40).
