The foldable microporous filter element is a precision filtration device made of polypropylene thermal spray fiber membrane, nylon, polytetrafluoroethylene (PTFE) microporous membrane and other filtration media. It has the characteristics of small volume, large filtration area, and high accuracy. The filtration accuracy range can be from 0.1uM to 60uM. The sealing of the filter cartridge end cap and the overall structural connection are all made by hot melt bonding. There are three internationally recognized types of filter cartridge connectors; 222 connector, 226 connector, flat mouth. The products undergo strict and comprehensive testing before leaving the factory to ensure stable performance.

The polypropylene microfiltration folding filter cartridge uses polypropylene material melt blown ultrafine fiber membrane as the filtering medium. It is a filter element with excellent deep filtration stability, and the nominal filtration accuracy range can be from 0.2 μ m to 0.6 μ m. The filter membrane is not affected by liquid fluctuations and does not affect the filtration accuracy. The unique fixed filter element with low pressure drop, high flow rate, and high filtration accuracy is highly popular. The folding filter element is composed of three layers of melt blown ultrafine polypropylene fiber filter cloth with different fiber fineness. The folding method is used as the filtering area and is integrated into the polypropylene inner and outer sleeves by hot spinning fusion. Therefore, its filtering area (0.6-0.7m2) is larger than that of the general standard deep type filter core (more than 10 times). Therefore, the characteristics of the filter element are "high filtering accuracy", "high compression resistance", "stable filtering performance", and "good chemical resistance".
