Product catalog summary
Overview
The Stratum Series Filter Cartridges are advanced melt blown filters designed for high performance in filtration, separation, and purification processes. Utilizing state-of-the-art melt blowing equipment and microprocessor-controlled environments, these filters offer consistent and reliable performance.

Specifications
Stratum Series filters are available in absolute and nominal ratings from 0.5 to 75 microns, with efficiency levels ranging from 90% to 99.9%. They are constructed with 100% virgin polypropylene, ensuring high purity and chemical compatibility.

Key Features
  • Consistent Performance: Microprocessor controls ensure consistent manufacturing conditions, resulting in reliable filter performance.
  • Longer On-stream Life: The 4-zone construction and optimized porosity provide true depth filtration and extended filter life.
  • Molded Center Core: The proprietary "Cactus Core" enhances collapse resistance and prevents flow restriction.
  • High Purity Construction: Free from surfactants, binders, and adhesives, suitable for critical applications.

Applications
  • Chemical/Industrial: Suitable for bulk and fine chemical filtration, process water, and more.
  • Microelectronics: Used in pre-RO filtration and bulk chemical filtration.
  • Water Treatment: Applicable in process, pre-RO, and ultrapure water prefilters.
  • Food and Beverage: Ideal for bottled water, wine prefiltration, and flavorings.
  • Pharmaceutical/Biotech: Used in utility water and ultrapure water systems.
  • Oil & Gas: Effective in water flood and natural gas filtration.

Performance Benefits
  • High removal efficiencies due to fine micro porous structure.
  • Consistent performance due to controlled manufacturing environment.
  • High collapse strength and excellent flow characteristics.
  • True graded depth filtration for lower filtration costs and longer filter life.

Comparison with Other Technologies
Stratum Series filters outperform conventional string wound, molded depth, and older melt blown filters by offering higher efficiency, consistent performance, and longer on-stream life.

Stratum Series Outperforms Competing Depth Filter Technologies Your process requires predictable and highly consistent removal of contaminants. While there are many types of depth filters available in the market, they do not all deliver the highest performance. Compared to competing technologies, Stratum Series provides the most reliable and advanced performance available in a depth filter. String Wound filters String winding is one of the oldest filter technologies and has a number of shortcomings. First, the string itself is coated with a lubricant or surfactant to make winding easier. These...
