The foldable filter is an emerging membrane separation filter with a cylindrical structure, made entirely of stainless steel SUS316L or SUS304. It uses a foldable filter element to filter liquids, gases, particles above 0.1μm, and bacteria. It offers high filtration precision, fast filtration speed, low adsorption, no media shedding, no leakage, resistance to acids, alkalis, and corrosion, easy cleaning, and backwashing capabilities. It is an ideal filtration device for industries such as biopharmaceutical pure water, beverages, biochemical water treatment, and environmental protection. Main Technical Parameters: Filtration Capacity T/H: 0.05-20 Filter Operating Pressure MPa: 0.1-0.6 Filter Element Specifications (Number of Elements): 1, 3, 5, 7, 9, 11, 13, 15, 19, 25, up to 100. Filter Element Operating Temperature °C: 5-80 PTFE Membrane Filter Element Temperature °C: 120 Characteristics and Applications of Various Filter Elements: PTFE membrane filter element, polyethersulfone (HE) membrane filter element, polypropylene (PP) membrane filter element, cellulose acetate (CN-CA) membrane filter element. Filtration precision ranges from 0.1-60μm. Available lengths: 10, 20, 30, and 40 inches (i.e., 250, 500, 750, 1000mm). These filter elements can withstand a pressure of 0.42 MPa and are backwashable. Connection methods include insert type (222 and 226 sockets) and flat nozzle type.
