Water Symmetric PES Capsules - 1

WPS Capsule Filters Symmetric Polyethersulfone (PES) Membrane Water Service Applications Process Water Ultrapure Water Pharmaceutical Waters WPS Capsules are hydrophilic and manufactured with symmetric polyethersulfone (PES) membrane. PES membrane exhibits excellent flow rates with high efficiency retention. WPS capsule filters are used for purified water filtration. The symmetric membrane used in WPS capsules guards against bacterial grow-through, reducing the potential for biofilm accumulation in systems. Polyethersulfone is particularly suited for high flow rate filtration. The membrane allows optimization for high flow rates and high throughput. Excellent flow rates with high efficiency retention High quality filtration of purified waters for multiple industries Optimized membrane design for high throughput WPS Capsule Filters - Filtration Area Capsule Length 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 1.0 ft² (930 cm²) of media with 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. 0.03 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 Symmetric Polyethersulfone (PES) Membrane Gases Operational Pressure Operating Temperature Media Support Forward Differential Pressure 50 psid (3.4 bard) at 20 °C (68 °F) Center Core Reverse Differential Pressure Outer Support Cage Sealing Method Thermal Bonding Recommended Changeout Pressure Water Service Grade

All Critical Process Filtration filters are made using materials that meet the FDA requirements for processing food and beverage products. These filters comply with Title 21 CFR sections 210.3 (b) (6) and 211.72, for non-fiber releasing filters. All materials used to make the filters are listed in European Commission Regulation EU/10/2011, Annex 1. WPS capsule filters generally exhibit low levels of non-volatile residues. Quality Assurance and Standards Critical Process Filtration uses state of the art computer controlled equipment to consistently produce high quality products as well as...
