摘要:
A filter (1) for diesel fuel comprising a tank (11), a filtering cartridge (2) which subdivides the inner volume of the tank (11) into two distinct chambers (50, 60), to which an input conduit (14) of the fuel to be filtered and an output conduit (15) of the filtered fuel are respectively connected, a heater (3), fed by means of electric current and adapted to melt the possible solid paraffins present in the fuel before they reach the filtering separator (21) of the cartridge (2), where said heater (3) has a porous surface (33, 34, 35) adapted to be crossed by the liquid component of the diesel fuel coming from the input conduit (14) and to hold the solid phase component, which forms at temperatures below the paraffination temperature, said porous surface (33, 34, 35) being adapted to be heated in order to liquefy said held solid component, so that it may cross said porous surface (33, 34, 35) in liquid form and reach the chamber (50) of the fuel to be filtered.
