A pressure filter is a mechanical device that uses a special filtering medium to apply pressure to the material, allowing the liquid to seep out. It is a commonly used solid-liquid separation equipment. It was first applied in chemical industry production in the early 18th century and is still widely used in industries such as chemicals, metallurgy, dye, food, brewing, ceramics, and environmental protection.

The filter plate boasts stable performance, easy operation, safety, and ease of use; the metal extrusion cylinder is precision-molded from seamless steel pipes and plastic steel filter plates, withstanding high temperatures and pressures for long-lasting durability.
