Pneumatic line magnets
September 1, 2011

Used to remove fine metal contaminants in dilute-phase pneumatic conveying, MPI pneumatic line magnets have a sanitary design in all product contact areas, quick-release clamps, 100% stainless steel product areas and rare earth magnet material. A food-grade, closed-cell gasket offers a permanent seal. Also available is a seam-welded, magnetic, stainless steel “raised” pole design that improves tramp metal retention between cleanings.
