Service Hydrophobic PVDF Capsules - 1

GPVWB Capsule Filters High Capacity Hydrophobic PVDF Membrane Tank Ventilation Non-Aqueous Solutions Solvents GPVWB capsules are made with high capacity hydrophobic PVDF membrane. The high capacity membrane provides high dirt holding capacity, excellent throughput and high efficiency particle retention. These capsules are designed for use in the filtration of non- aqueous liquids, solvents, and as compressed gas and vent filters. 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. Optimized high capacity membrane for maximum life Specific applications for GPVFB capsule filters include filtration of solvents, alcohols and other non-aqueous liquids. The hydrophobic membrane makes it ideal for final filtration of compressed air and process gases, and for vent filtration to prevent contaminants from reaching ingredients in tanks. Designed for filtration of air and process gases Vent filtration for protection of tank contents Final filtration of solvents, alcohols and other non-aqueous liquids GPVWB Capsule Filters - Filtration Area Capsule Length 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 General Service Grade High Capacity Hydrophobic PVDF Membrane
