Every opening (5) corresponds to a shallow channel (12), the shallow channels are parallel to the flow (14) of the water and are preferably raised over the internal concave surface of the emitter. The flow in the shallow channels (12) feeds continuously the collection channel (4) irrespectible if the surface of the openings (5) is covered or not by foreign particles (15). The openings (5) and the side walls of the filter are formed with the engraving of longitudinal, shallow and preferably radial channels on the cylindrical core of the mold that forms also the internal cylindrical surface of the emitter.
