<p>A combination filter (1) for diesel fuel, comprising an outer casing (2), a filter cartridge (5) dividing the interior of the casing (2) into two separate chambers (6, 7) to which an inlet conduit (3) for the diesel fuel to be filtered and an outlet conduit (4) for the filtered diesel oil are connected respectively, said cartridge (5) having a filtering capacity for the diesel fuel which is at least equal to that required by the specific application, said cartridge (5) comprising at least two filtering baffles (50, 51) associated with each other in such a manner as to be traversed in series by the diesel fuel to be filtered, that filtering baffle (50) more upstream with respect to the direction in which the diesel fuel traverses having a filtering capacity less than that required by the specific application but such as to retain the solid phase component of the diesel fuel which forms at the paraffin formation temperature.</p> |
