PROBLEM TO BE SOLVED: To contrive decrease in number of component items, price reduction, facilitation of assembly and weight reduction in a gaseous fuel filter in which filter element and permanent magnets are used in parallel. SOLUTION: Gaseous fuel flows from an entrance passage 2 to an exit passage 5 after passing a cylindrical filter element 14 and magnetic field of permanent magentas 21 placed in its inner space 17. Plural permanent magnets 21 are mounted on a supporting rod 15 with their same polarity poles facing each other, constant intervals are maintained between them by means of mutual reaction force magnetic field is regularly formed across the approximately entire inner space 17 and fine iron rust powder is completely removed. The interval holding means of the permanent magnets 21 is considered their own reactional force. |
