A fume extraction device including a fan for extracting fume-laden air from a cooking device in a room to an area located outside the room. The fume extraction device includes a pressure differential detection device for detecting the pressure difference (P<SUB>d</SUB>) between an inside pressure (P<SUB>i</SUB>) in the room and the outside pressure (P<SUB>a</SUB>) in the area located outside the room. The fume extraction device further includes a control device for controlling the air conveying capacity of the fan according to the (P<SUB>d</SUB>). |
