Device i.e. filter unit, for assembling on roof ridge of roof, has material which is obtained by reaction with water droplets for producing biocidal metal ions that control vegetation on roof

摘要

The device has a material which is obtained by reaction with water droplets (18) for producing biocidal metal ions that control vegetation on a roof. The device filters the droplets from an air flow (16) and delivers the droplets that are filtered from the air flow to a lee side of the roof. A strip element has a row of tooth and/or tines and/or lobes that are designed holohedral and comprises perforation holes. The strip element has a smooth or structured surface. The strip element has a bristle row consisting of bristles of same or different bristle cross sections and/or bristle lengths.
