Abstract
The invention relates to an optimized foam former () for foaming a foam-water concentrate, which foam former consists of a curved grate having diamond-shaped openings () and sharp edges (). The structure of the foam former increases the foam formation and ensures uniform distribution of the foam over a large area. Existing water sprinklers having a nozzle () and a spray disk () can be provided with the foam former () and thus converted into foam sprinklers in a simple manner. The foam former () is arranged in such a way that the foam former () protrudes beyond the spray disk () toward the nozzle ().
