11/12/09: New Stratum Series Advanced Melt Blown Filters Feature Proprietary "Cactus Core" and Captures and Prevents Unloading of Process Contaminants

Graver Technologies announces Stratum Series Melt Blown depth filter cartridges. The absolute rated Stratum A Series and nominal Stratum C Series are made on a state-of-the-art melt blowing line with all microprocessor controllers - the result is highly consistent, precise product that delivers repeatable performance in a wide range of applications. The four zone structure creates a true graded pore structure for excellent fluid clarification.

All Stratum Series filters are constructed with a proprietary "Cactus Core" that immobilizes the media and prevents unloading of captured contaminant. The multi-zone, graded pore structure excels in both on-stream life and flow versus the commonly available graded density products. Dirt holding capacity advantages of as much as 30% to 200% have been shown in laboratory testing. Customers confirm this outstanding performance in real world applications.

  • Stratum A - 0.5 to 70 micron at 99.9% efficiency
  • Stratum C Series - 0.5 to 75 micron at 90% efficiency
  • Multi-zone construction for a true graded pore structure
  • 100% pure polypropylene - FDA listed, USP Class VI compliant
