Abstract: A trailer (10) and a side skirt (19), each comprising an integrated arrangement (60, 70, 80) for reducing air drag, are provided. Each arrangement (60, 70, 80) comprises means for receiving air (60) comprising at least one air inlet (6), means for ejecting air (70) comprising at least one air outlet (7) facing downwards. The means for ejecting air (70) are arranged along a lower edge (11) of the trailer cargo housing (16) and side skirt (19) respectively. The arrangement also comprises means for conveying air (80) comprising at least one air duct (8). The means for conveying air (80) extend between the air receiving means (60) and the air ejecting means (70). The arrangement (60, 70, 80) is configured to produce a screen of air from the lower edge (11) and downwards during travel. The air screen prevents air, especially side wind, from entering the undercarriage.
