PPM Capsule Filters Polypropylene Membrane ulk Pharmaceutical Chemicals Compressed Air B Tank Vent Filtration PPM capsules are manufactured for the needs of the pharmaceutical industry. Made with inherently hydrophobic polypropylene membrane, these cartridges are designed for use in the filtration of non-aqueous liquids, and as compressed gas and vent filters. Each cartridge module is individually integrity tested using the water intrusion method before it is released from manufacture. O ptimized for maximum filter life Designed for final filtration of compressed air and process gases V ent filtration for the protection of tank contents Final filtration of solvents, alcohols and other nonaqueous liquids The capsule media surface area, filter core design, pleat configuration and pleat packing density have been optimized to provide increased life resulting in lower filtration operating costs. Specific applications for PPM capsule filters include final filtration of solvents and alcohols, final filtration of compressed air and process gas, and sterile vent filtration to prevent contaminants from reaching critical ingredients in tanks. PPM Capsule Filters - Filtration Area Capsule Length Polypropylene Membrane Flow Rate / Filtration Area The following table represents typical air and 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 fluids are water or compressed air at ambient temperature. Higher pressure drops are acceptable, but as flows increase the pressure drop of the housing becomes more apparent.

Integrity Test Specifications Pore Size Max Diffusion Rate (cc/min - 60/40 IPA/water wetted membrane) Pharmaceutical Grade PPM capsules are validated using test procedures based on ASTM Method F838-05 and HIMA protocols. The challenge level is 107 organisms per cm2 of filter media: 0.22 μm challenged with Brevundimonas diminuta; Critical Process Filtration can provide validation assistance. Quality Assurance and Standards The materials used to construct PPM capsule filters are non-toxic and meet the requirements for the MEM Elution Cytotoxicity Test and the requirements for Biological Reactivity...
