Abstract:

In a spin-on fluid filter assembly (10), means for magnetic filtration of ferrous-type particles upstream of the filter element is provided. The magnetic filtration means may include magnetizing the attachment plate (16) of the spin-on filter (12) and portions of the element housing (24). Magnetic spring clips (45) may be secured near the fluid inlet openings (30) in the attachment plate (16).
