Abstract
Means for Solving the ProblemAccording to an aspect of the present invention, there is provided a magnetic-separation filter device that removes contaminants of fine ferromagnetic particles from a fluid containing such contaminants, comprising: a substantially cylindrical housing; two partition plates that are disposed in an inside of the housing so as to extend in a vertical direction of the housing, dividing the inside of the housing by being disposed in parallel to each other;a filter medium that includes a fine amorphous-alloy wire bundle filled in a first region defined by the housing and the two partition plates; andplural permanent magnets that are provided on both sides of the first region outside the housing, wherein the contaminants of fine ferromagnetic particles are adsorbed on the filter media by flowing the fluid containing such contaminants through the first region in which the magnetic field has been formed by these plural permanent magnets.
