Abstract: A filter adapter for removing metallic particles from fluid. The adapter is cylindrical in shape and includes an attachment insert for mounting the adapter between a source in a fluid flow system and a conventional filter. The adapter has a ring shaped magnet held in the housing of the adapter by magnet holders. The adapter has a plurality of perforations in the top and bottom for the flow of unfiltered fluid from the fluid source, through the adapter, and to the conventional filter. The attachment insert is hollow so as to allow filtered oil to flow back from the conventional filter to the fluid system the adapter is attached to.

Abstract: A magnetic fluid filter for filtering metallic particles from a fluid flow system. The filter comprises a magnetic array, a central support for the magnetic array, and arm pieces for positioning the effective range of the magnetic array in a fluid flow environment. The magnetic array includes a plurality of disc shaped magnets arranged with poles in opposition, interleaved with the arm pieces and disc shaped pole pieces.
