Melt-blown filter cartridge and folding filter cartridge can be seen from the name, these are two different materials of filter elements, so what are the specific differences between them? It can be understood from three aspects.
First of all, the filtration performance, polypropylene melt blown filter cartridge and pp pleated filter cartridge filter filtration accuracy is different, pp spun filter cartridge filter filtration accuracy range is relatively narrow, mainly concentrated in 1-100 microns, mainly suitable for pre-filtration and coarse filtration; The filter accuracy range of the pleated membrane filter cartridge is relatively wide, between 0.1-60 microns, and it can handle the terminal filtration of high-precision filtration.
Secondly, the application field, pp melt blown filter cartridge application scenarios are generally used to focus on low-cost pre-filtration, such as industrial water treatment, food and beverage crude filtration or household water purifiers. The folding filter cartridge is mainly used in high-precision filtration scenarios, such as terminal filtration in high-end industries such as the medical industry and the electronics industry.
Finally and the most important is the production process, the spun depth filter cartridge is made of polypropylene particles by heating melting, spinning, traction, accept forming tubular filter element, one-time molding, simple process, low cost, pleated filter cartridge is the use of polypropylene composite film or microfiber film, through the folding process to form a multi-layer filter structure, the shell and end cap through hot melt welding Technical seal, no adhesive, avoid secondary contamination.
