Abstract
The invention is a compact in-line fluid filter. Two nested filter baskets have circumferential walls of fine mesh filtering media which is capture molded into a supporting structure. A magnet, transversely mounted to the fluid flow, attracts and retains ferromagnetic particles traveling in the fluid. This configuration provides a fluid filter with a larger filter area in a small package which is not position sensitive. Fluid entering the filter is divided into two parallel paths which have a low pressure drop. By distributing the flow and therefore trapped particles over the large filter area, a long service life is also attained.
