The characteristics of PES foldable filter element: The imported sulfonated polyethersulfone microporous filter membrane with excellent performance is selected, with high filtration accuracy and large flux. The support guide layer adopts imported high-purity polypropylene extruded mesh, without fiber shedding, with an effective area of up to super large, and a long service life. The biological safety of the PES folding filter structure material meets the USP 6 standard. Each filter element is cleaned with high-purity water before leaving the factory, greatly reducing the dissolved substances in the filter element. Before leaving the factory, each filter element undergoes strict integrity testing and is labeled with a separate number for quality tracking. PES foldable filter elements have wide chemical compatibility and strong applicability. Low protein adsorption capacity, also suitable for filtration of protein containing solutions and heavy pharmaceutical solutions.

PES foldable filter cartridge has the advantages of large filtration area, low initial pressure difference, fast flow rate, small filtration volume, and low manufacturing cost. Because pre filtration and final filtration are combined, the filter element has a great capacity to contain pollutants. The usage time is longer than that of a single hole filter element. It is easy to determine the chemical compatibility of pure polypropylene. The PES filtration membrane stack is formed by folding the polyethersulfone filtration membrane and the guiding layer. The end caps, shells, and middle pins of Type A filter are made of polypropylene material, while the end caps, shells, and middle pins of Type B filter are made of PVDF material, which can be used in high-temperature environments. The sealing of each part adopts adhesive free hot melt welding technology, forming a complete whole without chemical pollutants.
