Filter elements

摘要

A filter element has a non-magnetic frame defining a fluid flow opening. The non-magnetic frame has at least one mounting surface for mounting against a ferrous material. Two or more magnet-enclosing channels are supported by the non-magnetic frame. Two or more permanent magnets are provided within each magnet-enclosing channel. The permanent magnets are arranged with opposite poles facing one another. The permanent magnets apply a magnetic force through the at least one mounting surface to support the non-magnetic frame on the ferrous material.

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.
