Abstract (en)

[origin: EP0132872A1] The invention concerns a ventilation appliance comprising at least two angle-formed, vertical groups of louvre-element plates (90) in alternately opposed arrangement, both longitudinal edges of each louvre element being provided with a hook-shaped, back-fold formation (103) (104), both formations being located on the same face of the louvre element and in staggered opposition to those of the adjacent element whereby the internal protrusion of the formations(103, 104) causes a zig-zag pattern of the through-flowing air.
