A filter press is a device that applies pressure to accelerate the filter press process. It is mainly used for coarse filtration of activated carbon, pharmaceutical intermediate suspension and other materials. It adopts quick-opening pneumatic hanging lid, and the filter bag is hooped with nylon rope for quick cleaning and slag removal. Stainless steel pressure-resistant sintered filter element is used under high pressure. The pressure filter and the PA fine filter can filter out particles below 0.5um. The main feature of the filter press is that the feed is visible, the filtrate feed is large, and the slag discharge operation is convenient and clean.
