Service High Capacity PVDF Capsules - 1

GPVWL Capsule Filters High Capacity PVDF Membrane Applications Process Water Inks & Dyes Specialty Chemicals GPVWL capsule filters are hydrophilic and manufactured with high capacity polyvinylidene fluoride (PVDF) membrane. The proprietary membrane casting process creates a thick membrane with high dirt holding capacity, excellent retention characteristics and high flow rates. GPVWL capsules are used for critical applications in the processing of a wide range of liquids. Applications for GPVWL capsule filters include removal of particulate contaminants from purified process water, final filtration of DI water, inks, dyes and specialty chemicals. PVDF membrane is particularly suited for high volume filtration of product streams that contain elements that can adsorb to the media, such as preservatives. The very low binding characteristics of PVDF make it a good choice for inks, dyes, specialty chemicals and service fluids. Excellent throughput with high efficiency retention High quality filtration of process water, specialty chemicals, inks and dyes Optimized membrane design GPVWL 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. 0.22 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 High Capacity Polyvinylidene fluoride (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 PVDF Membrane
