TRAP Series


  • The used cutting fluid travels to a dirty tank from a gear grinder – any filtration magnets located inside the dirty tank capture magnetic metal powder – a scraper scrapes off the sludge – a roller squeezes out cutting fluid from the sludge – the sludge is discharged.
  • Cyclone-separator or backwashing filters remove non-magnetic grinding powder and binding agent from the cutting fluid – the fluid travels to a clean tank.


  • Magnets(using permanent magnets)can be used for both oil-base and water-base fluid.
  • Collect oil/fluid until the last drop, and recycle it.
  • 50% less industrial waste management cost in many case.
  • Low operation cost and low maintenance cost, 1/5 in many cases
