GNS Capsule Filters Nano-Spun, Hydrophilic Polypropylene Depth Media Applications Fermentation Broths Wine, Beer Inks & Dyes Bottled Water, Fruit Juices Specialty Chemicals Nano-Spun Depth Media GNS filter capsules are made using media produced in a tightly controlled process. The spun media is created by laying down graded density fibers on a spinning core. The result is a highly consistent product that provides 99% retention at the rated pore size and holds large amounts of contaminant. GNS media is ideal for protection of downstream membrane filters and performance of critical filtration applications. Nano-spun polypropylene for efficient retention and high dirt holding capacity These capsules can be used wherever it is critical to economically remove contaminants in high value liquids with high contamination loads. Applications include clarification of wine, beer, and fruit juices; prefiltration of fermentation broths and fluids used in making pharmaceuticals; prefiltration of bottled water; and filtration of specialty chemicals. They are also used as critical filters in applications such as CMP slurry polishing in semiconductor making as well as final filtration of inks and dyes. Remove contaminants in high value liquids Protection of downstream membrane filters Performance of critical filtration applications GNS Capsule Filters - Filtration Area 2” Nano-Spun Hydrophilic Polypropylene Depth Flow Rate / Filtration Area The following table represents typical water flow at a one psi (69 mbar) pressure differential across a single 2 inch capsule with a 2” (5.08 cm) nominal length depth filter module and 1/2” FNPT ports. The test fluid is water at ambient temperature. Higher pressure drops are acceptable, but as flows increase the pressure drop of the housing becomes more apparent. 0.5 μm Pore Size * For approximate flow rates for 5” through 30” capsules, refer to the appropriate cartridge data sheet Construction Materials Maximum Operating Parameters Liquid Operational Pressure Filtration Media Nano-Spun, Hydrophilic Polypropylene Depth Media Gases Operational Pressure Operating Temperature Media Support Center Core Outer Support Cage Sealing Method Thermal Bonding Forward Differential Pressure Reverse Differential Pressure Recommended Changeout Pressure General Service Grade Capsule Length

Integrity Test Information Representative sample capsule elements are factory tested for integrity before shipment. Field duplication of these tests is not practical because of the complexity of the testing process and absence of commercial portable testing equipment. All Critical Process Filtration capsule filters are designed to meet the FDA requirements for processing food and beverage products. The materials used to construct GNS capsule filters are listed by the FDA as appropriate for use in articles intended for repeated food contact as specified in Title 21 CFR sections 174.5, 177.1500,...
