Pentaring Hold Down Media

Saint-Gobain NorPro’s Pentarings provide a substantial improvement in pressure drop when used as bed topping media in a graded bed instead of the traditional use of sphere-shaped media. 

Pentarings are a dense media which allows for sufficient hold down capabilities, while having a high void fraction and increased surface area to provide a significant reduction in pressure drop. 

Advantages of Pentaring Media

Due to their unique shape, Pentarings have:

  • 22% increase in void fraction over spheres

  • Improved flow distribution

  • Increased capacity for trapping large particulates

Pentarings are also offered in a variety of sizes to fit your needs.
