The invention relates to built-in type axial flow air extractors for bathrooms and similar. The inventive extractor is of the type that comprises a support body formed by a cylindrical part which is intended to be embedded, a laminar part which is designed to fix the assembly to a wall or ceiling and which is essentially orthogonal to the cylindrical part, a blade-equipped propeller assembly and an electric motor which rotates the propeller assembly by means of an actuation shaft and which is housed in a casing. The invention also comprises damping means which are used to dampen the vibrations produced during operation and which comprise two elastic elements that connect the casing to the shaft in an elastic manner. The elastic elements, which have a discoid configuration identical to the interior of the casing, are disposed close to the ends of the shaft and remain coupled to the ends of the casing. |
