Precision filter is formed using the filter, under pressure, so that liquid through the filter, the filter residue left on the wall, and the filtrate flows through the filter, so as to achieve the purpose of filtering. Shaped filter are: filter cloth, filter, filter, sintered filter tubes, wound filter, melt-blown filter and so on. Vary the filter, the filter pore size is not the same. Precision filter is between the sand filter (coarse filter) with one between the UF filter, filter pore size is generally in the range of 0.5 ~ 120μm. The same forms of filters, dimensions can be divided according to different specifications. Precision filter Wirewound filter (also known as the honeycomb filter), there are two: one is a polypropylene fiber – polypropylene backbone filters, the maximum temperature 60 ℃; the other is cotton fiber – stainless steel frame filter, the highest temperature 120 ℃. Precision filter meltblown filter based on polypropylene as raw material, the process of forming the meltblown filter, the maximum operating temperature of 60 ℃. Precision filtration to remove suspended solids, some colloidal substances and fine particulate matter.
