FGD Capsule Filters Pleated Fiberglass Depth Media Applications Wine Soft Drinks Bottled Water Aseptically Packaged Liquids C omposite media filter rated at 99% retention at pore size High contaminant holding capacity as well as excellent retention W ide range of retention ratings Protect downstream membrane filters Applications for FGD capsule filters are clarifying filtration of wine, beer and other fruit juice based products. Bioburden reduction in fermented products such as wine and beer can be done efficiently with the FGD capsules. When used in final filling applications, the filters protect the critical membrane filters downstream. Fiberglass depth media filter modules from each lot are integrity tested during production. Filters are rinsed to assure no manufacturing debris remains in the finished capsules. FGD Capsule Filters - Filtration Area* Capsule Length Pleated Fiberglass Depth *Average – Filtration area varies with media thickness and porosity. 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. Pore Size 0.22 μm 0.30 μm 0.45 μm 0.65 μm * 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 Pleated Fiberglass and Polypropylene Composite Depth Media 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 Food and Beverage Grade FGD capsules are designed using composite media filter modules containing a fiberglass depth media and a final downstream layer of polypropylene depth media to ensure fiber free filtrate. They are rated at 99% retention at the rated pore size and have high contaminant holding capacity. These high performance capsule filters are used in clarification and pre-filtration applications as well as for bioburden reduction.

Integrity Test Information Representative sample capsule elements are factory tested for integrity before shipment. Field duplication of these tests is not practical because of the absence of commercial portable testing equipment. 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...
