ABSTRACT:
A false ceiling wherein a frame supports a set of elongated parallel horizontal trough-shaped slats each of which resembles or constitutes a portion of a hollow cylinder. The slats have longitudinally extending openings flanked by elongated marginal portions. The opening of one of each pair of neighboring slats faces upwardly, and the opening of the other slat of such pair faces downwardly. One marginal portion of one slat of each pair of neighboring slats extends into the interior of the other slat of the same pair and vice versa, and such marginal portions are spaced apart from each other to define passages wherein air can flow from the upper side to the underside of the false ceiling or in the opposite direction. The slats whose openings face upwardly collect liquid and/or solid constituents of air which flows upwardly and impinges against the concave undersides of slats whose openings face downwardly.
