The JUDO Mafi Magnetite Filter (iron sludge) removes particles by means of an optimized separation process – an efficient combination of centrifugal separation and the power of three high-performance earth magnets. Magnetic, iron sludge and non-magnetic particles are reliably separated, and heating systems are protected in the best possible way.

MAFI not only removes magnetic sludge and non-magnetic particles but also ensures that air and gas bubbles can escape by an automatic built-in air vent. If trapped, these bubbles would lead to corrosion in the heating system.

Judo Mafi is the perfect side stream magnetite filter for:

  • Closed loop heating-systems
  • Closed loop chilled systems
  • Boilers
  • Condensate return systems.

  • Automatic built-in air vent 
  • Removes magnetite sludge - iron sludge and air 
  • Protects pipes, boilers, pumps, cooling towers, regulators and other mechanical components
  • Component lifetime extension
