Friess magnetic filter FMF with cleaning insert

The Friess Magnetic filter system FMF with cleaning insert removes ferritic particles from coolant, cutting oil, grinding oil and other process fluids.

Particles which are smaller than the pore size of the filter media will pass the filter media together with the fluid. The number of small particles in the fluid will grow continuously.

The Friess magnetic filter system FMF with cleaning insert removes ferritic particles of all sizes down to 1 µm.

The Friess magnetic filter series FMF removes steel particles and iron particles. In addition to that the magnetic filter removes paramagnetic particles like stainless steel, hard metal and other. 

In order to clean the magnetic filter FMF you have to remove the magnetic rods out of the cleaning insert. Without the magnets it is easy to clean the outside of the magnetic insert from collected particles.

The magnetic filter FMF with cleaning insert is available in two different sizes:

FMF 150/5 with 5 magnetic rods

FMF 200/7 with 7 magnetic rods


  • Removes particles down to 1 µm
  • Does not need any consumables
  • No additional energy necessary
  • No cost for waste disposal because the collected sludge can be recycled
  • Drastically reduced operation cost due to longer lifetime of coolant or grinding oil
  • Improved surface quality because of clean coolant


  • Coolant
  • Grinding oil
  • Honing oil
