An air vent, particularly a ceiling mountable air vent for ventilation and air-conditioning systems with a variable air in-flow volume, comprises a hollow cylindrical air vent casing (2) having an axially directed air inlet (3) and a radially directed air outlet [5). An axially movable deflection member (7) is mounted within the casing for deflecting air introduced through the inlet (3) towards the outlet (5). IMAGE
