An air treatment unit for treatment of an air stream, including a pad having a multitude of narrow air-flow channels, the walls of which are formed by corrugated sheets of a stiff material, the sheets being positioned and fixed generally in parallel planes next to each other in such a way that, as seen from an inlet side of the pad to an outlet side thereof, the channels formed by the corrugations of any two sheets located next to each other extend in two different directions the vertical plane of the respective sheet. At least in a central region of the pad, all sheets are positioned obliquely sideways, whereby all channels extend obliquely sideways relative to inlet and outlet surfaces of the pad.

1. An air treatment unit for treatment of an air stream flowing in a substantially horizontal direction and being blown through the unit from an inlet side to an outlet side, said air stream interacting with water pouring downwardly through said unit comprising at least one pad having a substantially vertical inlet surface, an outlet surface and a plurality of narrow air-flow channels extending from said inlet surface to said outlet surface, the walls of said channels being formed by corrugated sheets of a stiff material, said sheets being positioned and fixed generally in mutually parallel, substantially vertical planes next to each other in such a way that the channels formed by the corrugations of any two adjacent sheets extend in two different directions from said inlet surface to said outlet surface, wherein:at least in a central major region of the pad, said mutually parallel, substantially vertical planes of said corrugated sheets are oriented obliquely relative to a substantially horizontal direction being normal to said inlet surface, whereby said air-flow channels extend obliquely, not only in said two directions in said mutually parallel planes, but also obliquely sideways in a third direction, as seen in said substantially horizontal, normal direction, as a consequence of said oblique orientation of said mutually parallel planes.
