An air vent comprising a housing, an air inlet opening, which is located in the axial direction of the housing, and an air outlet opening, which is disposed opposite the air inlet opening, a first air guide surface, which has a first bulge and is disposed in the housing, and a second air guide surface, which has a second bulge and is disposed in the housing, wherein the first bulge points in a first direction and the second bulge points in a second direction, wherein the first direction and the second direction oppose one another and extend perpendicularly to the axial direction, wherein the first air guide surface and the second air guide surface are disposed at a distance from the housing, wherein a first air duct is formed by the housing and the first air guide surface, and wherein a second air duct is formed by the housing and the second air guide surface, wherein the first air duct is designed to convey a first volumetric flow of air—which can flow into the housing through the air inlet opening—to the air outlet opening, wherein the second air duct is designed to convey a second volumetric flow of air—which can flow into the housing through the air inlet opening—to the air outlet opening, comprising a first vane and a second vane, wherein the first vane is movably disposed at the end of the first air guide surface facing the air inlet opening, and wherein the second vane is disposed at the end of the second air guide surface facing the air inlet opening, wherein the movability of the first vane and the second vane is designed such that the ratio of the first volumetric flow to the second volumetric flow can be adjusted by means of the position of the first vane and the second vane.
