Abstract (en)

The element has metal supports (14) arranged parallel to each other and perpendicular to parallel metal lamellas (13), where the lamellas have a triangular profile and are fixed on the supports by welding. Each support is a mono-block piece presenting a U-profile with a core (15) extended on both sides by two legs (16) perpendicular to the core. One series of the lamellas are welded to the cores of the supports and other series of the lamellas are welded to the legs. Each support has a rib (20) projected on an outer edge (21) on which the lamellas are welded. Independent claims are also included for the following: (1) a method of manufacturing a filtering element (2) a device for separating a carrier fluid of cleaning bodies.
