Abstract:
A magnet assembly for use with a filter having a ferrous metal housing for removing ferrous metal particles from a fluid circulating through the filter comprising a disc shaped magnet having a face, a plurality of circumferentially spaced pairs of poles on said face that concentrate the magnetic strength of the magnet on said face for focusing on the filter housing when the magnet is attached to the filter housing causing the ferrous metal particles in the fluid to be trapped against interior walls of the filter housing, said magnet face having inner and outer sides and an outer edge, and a cup-shaped plastic housing protectively covering said outer side and said outer edge of said magnet face, said magnet having a center opening extending through said face for receipt of a nut on the filter, said plastic housing covering said opening adjacent said outer side of said magnet face.
