A device for delivering air or other gas into the area of a skin fold in order to dry the skin and thereby prevent the development of inflammation, rash, or infection features an air manifold that connects to an air or pressurized gas source. The manifold delivers air to a distribution layer, which then distributes air along the length of the skin fold when the layer is within the fold. The distribution layer is formed of a gauze material, with a plurality of tubular longitudinal sections of gauze connected by flat sections of gauze. The distribution layer is fitted between a top and bottom half of the manifold, held fast by spikes extending from within the halves.
