HDC® II Filter Cartridges

Pall HDC II all-polypropylene filter cartridges incorporate proprietary HDC II tapered pore polypropylene depth media. The single open-ended (SOE) AB filter cartridge style features a high-area pleated modular element construction designed to fit in sanitary filter housings. HDC II filter cartridges are well-suited for a broad range of fine particle and prefiltration applications where purity, economy and reliability are critical. Typical applications include biologicals, pharmaceuticals, fermentation feeds and intermediates, and vaccines.
