Magnetic filters function as a more comprehensive solution for removing ferrous contaminants from various liquids or gases. These filters consist of multiple magnetic elements arranged to maximize the capture of particles as the fluid passes through the filter. The magnetic force immobilizes the contaminants, preventing them from circulating further downstream.

On one hand, magnetic filters are utilized in chemical processing industries to remove metal particles from liquids, ensuring the purity of chemical products. On the other hand, in machining processes, magnetic filters are employed to keep coolants and cutting fluids free from metal debris, thereby extending the life of cutting tools and improving machining accuracy.
