Abstract:
1. A filter element for magnetically filtering ferrous material from a fluid flow, comprising: a rectangular non-magnetic frame having an inner surface defining a fluid flow opening, and at least one outer mounting surface opposite the inner surface for mounting against a ferrous material; at least two peripheral sides of the rectangular non-magnetic frame comprising channels, each channel defining a frame magnet-isolating cavity; at least one louvered channel spaced from the peripheral sides of the rectangular non-magnetic frame and traversing the fluid flow opening, the louvered channel defining a louvered channel magnet-isolating cavity; and two or more permanent magnets within the frame magnet-isolating cavity of each of the channels and the at least one louvered channel magnet-isolating cavity, such that the magnets are physically isolated within the respective magnet-isolating cavity from the fluid flow.
