Polypropylene Filter Cartridge
MLDPP series polypropylene filter cartridge is designed and manufactured for pharmaceutical use. All of them are manufactured in clean room conditions and meet the requirements of the USP VI and are food conformed. All components are made from Polypropylene, thermic-welded and free of binders, adhesives or additives. This type of depth filter cartridge retains particles with ab-solute efficiency. Available in a broad range of pore sizes and length make many options for practical application. The pleated construction provides a high surface area to offer outstanding overall filtration economy.
