PORAL® filters are obtained by sintering of defined granulometry powders. Their unique structure provides, in barrier or in-depth, an optimized and sustainable filtration solution.
Sintered filtration media are appreciated thanks to their sinuous but regular porosity.

PORAL® products are showing many advantages:

  • high corrosion resistance
  • high mechanical strength
  • wide range temperature resistance
  • easy cleaning
  • easy to weld or machine
