It is widely used for liquid impurity filtration in food, beverage, pharmaceutical, chemical and other industries. Made of stainless steel with optional filter precision, it features compact structure and easy operation. Filter switching and cleaning can be realized without shutdown to ensure continuous production. It effectively removes suspended solids and particles to improve product purity and hygiene level, making it a common precision filtration equipment in fluid production lines.
