摘要： The air distributor (2) serves for the aeration of a water volume, in particular for the aeration of wastewater in a sewage basin. Said air distributor comprises a support (4, 6) and an air distributor foil (8) fastened thereto, into which air distributor foil there is formed, for the release of air into the water volume in fine jets, a perforation with individual, self-closing air passage openings (10). The air distributor foil (8) has a multi-layered construction with a functional layer (20) on the wastewater side, and has an elastic sealing layer (24). Substances (28) with functional action are integrated into the function layer. Alternatively or in addition, the function layer forms a hydrophilic surface (12). The self-closing characteristic of the air passage openings (10) is ensured by way of the sealing layer (24). A third support layer (22) is expediently additionally formed, which third support layer exhibits lower elasticity than the sealing layer (24), such that, even in the presence of high wastewater temperatures, excessive bulging of the air distributor foil (8) is avoided, and the permanent elasticity of the sealing layer (24) is ensured. By way of the multi-layer construction, opposing demands on the material characteristics of the air distributor foil (8) are met in a suitable manner.
