摘要： The invention concerns a filtering element provided with a central opening (16) and designed to be assembled with an element of similar type to form a filter, each filtering element (1) comprising two surfaces respectively internal (2) and external (3) to the filter, an internal rim (5) defining the central opening (16) periphery and an external peripheral rim (4) between which is mounted a sieve (6) parallel to said internal (2) and external (3) surfaces, each surface of the element further including radial ribs (72, 73) extending opposite each other between the external (4) and the internal (5) rims to form on the internal (2) and external (3) surfaces angular sectors (21, 31). The invention is characterised in that each of the internal (2) and external (3) surfaces comprises at least sixteen angular sectors (21, 31), each formed by a free portion of the sieve (6) and the ratio of the sieve (6) free surface over the element (1) total surface ranges between 55 % and 68 %.
