<p>The filtering cartridge structure comprises a filtering septum formed by a thin central filtering member (4) including three layers glued one to another by lamination, the intermediate layer (17) thereof consists of two microfibres bound by a binding material, the other two layers (18, 19) being formed by polyester resin fibres, sealed or welded one to another by hot calendering. The mouth (2) and bottom portions (1) portions are coupled to one another by means of a coupling (13) or fixing member and the bottom portion is devoid of any counterdrawn portions in order to prevent condensate from accumulating. Two filtering septum supporting walls (8, 9) are located concentrically with respect to the two sides of the filtering septum and are formed by means of a simple sealing or welding operation, without using further fixing means.</p> |
