The invention relates to a tap aerator (1) comprising a mounting housing and containing, in said mounting housing (2), an insert part that is designed as a jet divider and diffuser (7) which interacts with a diffuser ring (8). The annular retainer regions (7a) and (8a) of said diffuser (7) and diffuser ring (8), each arranged on the largest outer circumference, are located, when in a use position, in the interior of the mounting housing (2) at different height positions relative to one another in the axial direction, i.e. the retainer region (7a) of the diffuser (7) is not enclosed and the largest outer diameter of the diffuser ring (8) and its retainer region (8a) is only as large as, or if required even smaller than, the largest outer diameter of the diffuser (7) and its retainer region (7a). This allows the formation of an arrangement which saves space in the radial direction.

The insert with a rotating mesh for aerators in sanitary fixtures consists of the housing (1) of an insert, the rotating screen (5) and o-ring (6). The housing (1) of an insert has at its bottom part i.e. at the water outlet of the sanitary fixture, two bearings (2) made, the rim (4) for installing a flat sealing between the sanitary fixture and the body of aerator. The rotating mesh (5) has on its rim circumference, preferentially at the most extended part of the rotating mesh (5), i.e. at the extension of diameter of the mesh (5) two axles (7) positioned which fit into the bearings (2) in the housing (1) of the insert, and serve for axle fixing the rotating mesh (5) and thus enabling the rotation of the rotating mesh (5) around the axles (7); the rotating mesh (5) has on its outer circumference, in the upper part, a groove (11) cut, in which o-ring seal (6) is installed for sealing the rotating mesh (5) to the housing (1) of the insert. Optionally, the rotating mesh (5) can include on its circumference, i.e. at the water outlet of the sanitary fixture, also the intake channel (15) for air supply. The intake of air for aeration is provided from the bottom side laterally. Optionally a rotating mesh can be installed directly in the aerator's body without an insert. In this context, the rotating mesh (5) is fixed axially with two screws (12) directly in the body (13) of the aerator in a way that it is rotatable around its axis.
