Magnetic Filters

FRIESS magnetic filters remove particles and pollution from every kind of process fluid like cooling lubricant, washing water, cooling water, fuel and many more in a cost-efficient way and without consumables. Highly effective neodymium magnets are applied in a filter housing made out of stainless steel. Because of the extremely high magnetic field force ferritic particles like iron, steel, stainless steel or carbide are attracted by the magnetic core. The clean fluid flows through the outlet back into the system. The special concipated flow around the magnetic core in a slow and laminar fashion, makes it possible that small particles down to 1 µm are removed. The magnetic filter works without consumables and does not require any operating energy. No pressure differential is created by the magnetic filter. Even with saturated filter rods, the fluid can pass through the filter without loss of pressure. Despite an occasional cleaning, no maintenance is required.

Grade of Automation:
Magnetic Filter FMF
A basic magnetic filter that removes iron, steel and stainless steel particles from all types of process fluids.


  • Separation of smallest particles down to 1 µm
  • No consumables required
  • A clean cooling lubricant procures an improved surface quality and a better grinding pattern
  • Less abrasion of machines and tools
  • Increased durability of cooling lubricants
  • Reduced disposal costs
  • No energy costs or losses, apart from semi-automatic and fully automatic versions
