Zhenxing stainless steel filter bag is welded with 304/316 stainless steel mesh; it is characterized by high strength and will not be deformed due to changes in pressure; compared with traditional five-wire edging, its temperature and pressure resistance is more significant; At the same time, the monofilament weaving constitutes a smooth surface, which is easy to clean and can be used repeatedly. It is suitable for some liquid filtration with high impurity content, thereby reducing the filtration cost.
