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 ().

Foam former and foam sprinkler

A cage for generating fire-fighting foam from fluid containing foaming agent released from a sprinkler may be constructed from woven screen or expanded lattice having screen openings having a diameter between 1 mm and 7 mm and/or lattice openings having a width between 1 and 7 mm and a length between 2 mm and 9 mm. The cage has dimensions which permit an intermediate space between a fluid exit opening and spray plate of the sprinkler to be surrounded radially with a height and a width: the height corresponds to at least 0.20 times the external diameter of the spray plate; the internal diameter of the cage, alternatively the non-circular minimum spacing between the opposite internal sides of the cage, at the level of the spray plate, corresponds to at least the external diameter of the spray plate.
