A louver arrangement (20) configured to be attached to an air-conditioner is provided. The louver arrangement comprises a, first, main louver (22), and a, second, crank louver (24). The main louver and the crank louver are rotatably connected to each other. Hereby the main louver and crank louver work in cooperation. The main louver is configured to direct a main air flow from an air-conditioner outlet when mounted on an air-conditioner, and the crank louver is configured to be located closer to a lower wall of the air-conditioner outlet when mounted on an air- conditioner and configured to, at least in some positions, to enable deflection of a fraction of air flow onto the main louver when in use on the air-conditioner.
