Engineered to remove medium and fine ferrous contaminants from dry, free-flowing products under gravity flow, Puritan manual-clean drawer magnets have multiple staggered rows of magnetic tubes for a larger product flow contact area. As product flows through the stainless steel housing, it cascades over the staggered rows, and ferrous contaminants are pulled to the surface of the magnets where they move to the underside of the tubes to prevent washoff.
