Our ZGJ Vacuum Filter is mainly used to filter the rolling solution in cold rolling of ferrous metal and hot rolling of nonferrous metal. It is the key equipment which assures the filtering precision of rolling solution; in hence, products’ furnace is satisfied with technical requirement. Vacuum filter includes 25 specifications; filter capacity is 1000-25000L/Min. It is called HOFFMAN in western countries, which is applied in metallurgy. ZGJ Vacuum Filter is automatic machine; electric control applies PCL. Moreover, it has many advantages, such as high filtering precision, high efficiency pressure filter. The whole process is controlled by pressure, timing, and fluid location. Emulsion is achieved with continuous filtration, cycling filtration and full filtration. ZGJ filter operates well and be a high automatic equipment. We can manufacture according to customers' requirements.
