GPS Capsule Filters Polyethersulfone (PES) Membrane Applications Process Water Inks & Dyes Specialty Chemicals GPS Capsules are hydrophilic and manufactured with polyethersulfone (PES) membrane. PES membrane exhibits excellent flow rates with high efficiency retention. GPS capsule filters are used for removal of particulates from process water, and for final filtration of DI water, inks, dyes and specialty chemicals. Polyethersulfone is 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 efficiency retention High quality filtration of process water, specialty chemicals, inks and dyes Optimized membrane design for high throughput GPS 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 Gases Operational Pressure Media Support Operating Temperature Center Core Outer Support Cage Sealing Method Thermal Bonding Forward Differential Pressure 50 psid (3.4 bard) at 20 °C (68 °F) Reverse Differential Pressure Recommended Changeout Pressure General Service Grade

FDA and EC Compliance All Critical Process Filtration capsule filters are designed to meet the FDA requirements for processing food and beverage products. The materials used to construct GPS capsule filters are listed by the FDA as appropriate for use in articles intended for repeated food contact as specified in Title 21 CFR sections 174.5, 177.1500, 177.1520, 177.1630, 177.2440 and 177.2600 as appropriate. Membrane 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...
