FCNA cartridges are designed to deliver precision filtration through the patented, advanced melt-blown CoLD™ technology structure. Absolute filtration with sharp particle cutoffs deliver precise removal efficiencies with outstanding retention efficiency, mechanical strength, and long on-stream life. This high purity filter is made of 100% polypropylene and is free of surfactants, binders, and adhesives - making them ideal for use in food and beverage applications. Multi-zone design produces a gradient pore structure to provide pre and post filtration in a single cartridge.
