Double-Layer PES Capsules - 1

DPS Capsule Filters Double Layered Polyethersulfone (PES) Membrane Applications Process Water Inks & Dyes Specialty Chemicals DPS Capsules are hydrophilic and manufactured with two layers of polyethersulfone (PES) membrane optimized for the highest filtration area and solids holding capacity. PES membrane has excellent flow rates. DPS capsule filters are used for removal of particulates from process water, and for final filtration of DI water, inks, dyes and specialty chemicals. DPS capsule filters are particularly suited for high flow rate filtration of product streams that contain high contaminant loads and have elements that can adsorb to the media, such as preservatives. The lower binding characteristics of PES membrane make it a good choice for inks, dyes, specialty chemicals and service fluids. Excellent flow rates with high solids retention capacity High quality filtration of process water, specialty chemicals, inks and dyes Optimized double layer membrane design for high throughput DPS 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 Double Layered 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 General Service Grade Double Layered PES Membrane
