Our cartridge design magnetic liquid filters or Magnetic Traps are designed to ensure maximum contact is made between product and the magnetic fields by forcing liquids through a tightly spaced grid of magnets. These Cartridge Style Magnetic Liquid Filters are engineered for use with non-fibrous fluids. Ferrous contamination is magnetically extracted from the liquid flow by the extremely powerful Rare Earth magnet design  and held firmly on the cartridge surfaces. Simply and quickly cleaned by removing the magnetic lid assembly from the filter housing and wiping off the collected metal particles.
