Biopharm Hydrophobic PVDF Capsules - 1

BPVWB Capsule Filters High Capacity Hydrophobic PVDF Membrane Tank Ventilation Non-Aqueous Solutions High capacity membrane for maximum filter life The capsule media surface area, filter core design, pleat configuration and pleat packing density have been optimized to provide increased life resulting in lower filtration operating costs. D esigned for filtration of air and process gases Vent filtration for the protection of tank contents BPVWL Capsule Filters - Filtration Area Capsule Length High Capacity Hydrophobic PVDF Membrane Flow Rate / Filtration Area The following table represents typical water or air/gas 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 fluids are water or compressed air at ambient temperature. Higher pressure drops are acceptable, but as flows increase the pressure drop of the housing becomes more apparent. 0.22 μm Water Flow Rates (gpm) Air/Gas Flow Rates (scfm) 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 High Capacity Hydrophobic PVDF 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 Biopharmaceutical Grade Biopharmaceutical grade PVWB capsules are manufactured for the critical needs of the pharmaceutical and biotech industry. Made with high capacity hydrophobic polyvinylidene fluoride (PVDF) membrane, these capsules are used for compressed gases, and as vent filters. The high capacity membrane provides high dirt holding capacity, excellent throughput and high efficiency particle retention. Representative filter modules are integrity tested before lot release from manufacturing to assure consistent performance.

Integrity Test Information Quality Assurance and Standards Biopharmaceutical grade filters typically exhibit low levels of non-volatile residues. The materials used to construct BPVWB capsule filters are non-toxic and meet the requirements for the MEM Elution Cytotoxicity Test and the requirements for Biological Reactivity Tests in the current version of the United States Pharmacopeia (USP) for Class VI - 121 °C Plastics. In addition, the materials meet the requirements listed by the FDA as appropriate for use in articles intended for repeated food contact as specified in Title 21 CFR...
