4th Generation Random Packing

This Third Generation of random packings is well known as FlexiMax with higher performance, efficiency, and Capacity provide lower pressure drop compared to conventional random packings.
besides, this type can tolerate more pressure under deep beds without mechanical deformation.

This 3rd generation of random packing media designed to give enhanced capacity and increased efficiency over the older style Pall Ring packing. This type of packing combines the high void fraction and the well-distributed surface area of the Pall Ring with the low aerodynamic drag of the saddle shape. This kind of random packing is used widely in separation columns. By comparison to the PR Series, PantaRing™ IR series provides a more open shape and improved liquid spread, also produce adequate mechanical strength resistance. This type is a direct replacement of well known IMTP packing.


  • 30% lower pressure drop rather than Pall Rings
  • More efficiency and capacity rather than other random packings
  • Minimum liquid hold up
  • Well surface utilization in transfer phenomena
  • Shorter packed bed height
  • Outstanding mechanical strength
