ZSJ-PP polypropylene folding filter cartridge Using polypropylene composite filter membrane as the main filtering material, this type of filter element is an advanced fixed deep filter element, with a nominal filtration accuracy range of 0 1 μ m to 60 μ m. The filter membrane is not affected by the fluctuation of feed pressure, which affects the filtration accuracy. Its unique advantages such as low pressure difference, high throughput, good filtration accuracy, and low economic cost are highly favored by users. Characteristics of ZSJ-PP Polypropylene Folding Filter Element 1. Adopting imported and domestic ultra-fine polypropylene fiber filter materials, as well as imported non-woven fabric or mesh support layer folding 2. The entire polypropylene structure is sealed and formed using hot melt welding technology, without any adhesive, pollution, and fiber shedding 3. Uniform pore size distribution, wide filtration accuracy range, low pressure difference, large flux and pollutant…
