Candle filters have a small footprint and are used in coolant filtration for EDM, tungsten carbide tool grinding, honing, and bearing grinding applications with replaceable filter elements that last several years.

PRAB’s Candle Filter improves coolant recycling systems and fluid reclamation by using media in a long cylinder that houses more than 10,000 thin membrane wafers. These membranes effectively and consistently capture grinding swarf down to 1-3 micron and operate reliably under large production runs for improving fluid waste management.

Advantages of the candle filter include:

  • Improves coolant recycling and fluid reclamation
  • Filters operate with virtually no downtime for maintenance
  • Performs reliably under large production runs
  • 10,000 thin membrane wafers capture grinding swarf down to 1-3 micron
  • Self-cleaning air pressure backflush cycle reduces labor costs and increases process efficiency
  • Swarf is purged into an external receptacle for easy collection and recycling in coolant filtration
