VPS Capsule Filters Dual Layered Polyethersulfone (PES) Membrane Applications Wine Process Water Clean-in-Place Solutions Aseptically Packaged Liquids Bottled Water VPS Capsules are hydrophilic and manufactured with asymmetric polyethersulfone (PES) membrane in a unique, dual-layered, graded density design. Polyethersulfone membrane exhibits excellent flow rates with high efficiency retention ratings. A unique, graded density design Excellent flow rates with high efficiency retention ratings Polyethersulfone is particularly suited for the filtration of products that contain elements that can adsorb to the media, such as flavor elements and proteins. The lower binding characteristics of PES avoid adsorption and make it an excellent choice for filtration of beer and wine. F inal filtration of wine, beer and other organically complex beverages Low product adsorption to preserve flavor VPS 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 Gases Operational Pressure Prefiltration Media Operating Temperature Media Support 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 Wine and Beverage Grade VPS capsule filters remove unwanted organic components while allowing the high value flavor elements to pass through the filter. This performance characteristic is ideal for final filtration of wine, beer and other organically complex beverages like juices.

Integrity Test Specifications Pore Size Max Diffusion Rate (cc/min -water wetted membrane) All Critical Process Filtration capsule filters are designed to meet the FDA requirements for processing food and beverage products. The materials used to construct food & beverage grade 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....
