Magnetic Separators for Coolant and Fluid Filtration

Cost-effective removal of ferrous fines to protect tools, improve surface finish, and reduce downtime.

PRAB magnetic separators continuously remove ferrous chips, sludge, and fines from water-based coolants and straight oils. Using high-intensity rotating drum magnets, these systems capture contaminants before they reach downstream filtration equipment—extending coolant life and protecting machining processes.

Magnetic separators are commonly used in grinding, honing, gear cutting, and other operations where fine ferrous particles are suspended in coolant. As pre-filters or standalone solutions, they help maintain fluid clarity and consistent machining performance.

Key Benefits

  • Removes high levels of ferrous particles and sludge
  • Reduces machine downtime by up to 50%
  • Prolongs tool life and improves part surface finish
  • Continuous, automatic operation
  • No consumable filter media required
  • Supports coolant recycling and reuse goals

How Magnetic Separators Work

PRAB magnetic separators use a rotating drum fitted with high-intensity ferrite or rare-earth magnets. As contaminated fluid flows across the drum, ferrous particles are captured magnetically and carried out of the fluid stream. The cleaned fluid then continues to downstream filtration or back to the process.

This approach provides continuous separation without filter media, reducing maintenance while maintaining consistent coolant quality.

Typical Applications

  • Centerless grinding
  • Heavy stock removal grinding
  • Honing operations
  • Gear cutting machinery
  • Machine tools using water-soluble or neat oils

Available Magnet Types

Ferrite Magnet Models

  • 1,200–1,600 gauss ratings
  • Removes up to 97% of ferrous particles larger than 40 microns
  • Suitable for general grinding and machining applications

Rare-Earth Magnet Models

  • 3,600–4,200 gauss ratings
  • Up to 12× stronger than ferrite magnets
  • Removes up to 97% of ferrous particles larger than 15 microns
  • Ideal for fine sludge, high-viscosity oils, or heavy contaminant loads

Performance Range

  • Flow rates from 5 to 315 GPM
  • Multiple models available to match process requirements
  • Often used as a pre-filter ahead of paper bed, vacuum, or membrane filtration systems

Operational Advantages

  • Continuous, automated separation
  • Reduced coolant disposal and replacement
  • Improved machining consistency
  • Lower maintenance compared to media-based filters

Ferrite Magnet Models:

  • The MCA product line features ferrite magnets with a 1,200 Gauss rating
  • The MCJ product line features ferrite magnets with a 1,600 Gauss rating
  • MCA and MCJ units remove up to 97% of all ferrous particulate in excess of 40-micron

Rare Earth Magnet Models:

Rare earth models are used when there are large amounts of ferrous fines (smaller than 40 micron), large amounts of sludge accumulation in a machine’s coolant tank, or when the coolant has a high viscosity rating such as straight oil.

  • The SS product line utilizes Rare Earth Magnets rated at 3,600 gauss, which are 10X stronger than ferrite magnets
  • The MSK product line utilizes Rare Earth Magnets rated at 4,200 gauss, which are 12X stronger than ferrite magnets
  • SS and MSK units remove up to 97% of all ferrous particulate in excess of 15-micron

Magnetic separators employ high-intensity ferrite or rare earth magnets within a fully energized rotating drum to continuously remove ferrous particles from the flow of liquid. This scrap metal equipment is often used as a pre-filter to limit contaminants reaching subsequent filtration equipment and are well suited to processes where ferrous and non-ferrous contaminants are mixed with water-based coolants or straight cutting oils. PRAB offers 4 models depending on your application needs.
