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.
