A furnishing device comprises liquid carrying fill sheets which are juxtaposed and vertically corrugated and define therebetween passages for a gas, said sheets comprising in succession, in a direction parallel to the crests of the corrugations at least two regions in which the corrugations have different amplitudes, namely a region having corrugations of large amplitude and a region having corrugations of small amplitude which are interconnected by a transition region. Each sheet has at intervals along the crests of its corrugations spacer devices by means of which one sheet may be fixed to an adjacent sheet and maintained out of contact with the latter except in the region of the spacer devices. |
