<p>The aerator (1) has a body (4) having openings (5) formed therein and containing meshes (6) and a perforated plate (7). A monolithic convex diaphragm (8), defining a wall (8a), has holes (8b,8c) formed in a central region thereof and a perimetric (8d) ultrasonically welded to a seat formed in the plate (7). The convexity of the diaphragm (8) is oriented in a fluid flow direction, whereby retained particles are collected at the base of the perimeter of the diaphragm (8). <IMAGE></p> |
