The bag filter is a highly efficient and economical solid-liquid separation device that intercepts impurities, suspended solids and particles in liquids through built-in filter bags. It is widely used in chemical, food, beverage, phar, coating and water treatment industries. The equipment body is made of stainless steel 304/316L, featuring corrosion resistance, easy cleaning and compliance with hygienic production standards. With compact structure, large filtering area, low resistance and high flow capacity, it allows quick and easy filter bag replacement with low operating cost. Various filter bag specifications can be selected according to different media and precision requirements to achieve coarse or fine filtration. It effectively protects downstream equipment and improves product purity, making it an ideal impurity filtering solution in industrial production.
