UHA series large-flow foldable filter core adopts a 6-inch large diameter structure, with extremely high filtration area. The fluid flows from the outside to the inside, which has a high-strength polypropylene support framework to prevent deformation of the filter material. The external support is divided into two structures: the integrated polypropylene framework and the polyester filter network. With good high temperature resistance and wide chemical compatibility, the filter and filter system has the advantages of high flow, small size and low investment. The inner filter core is made of polypropylene, and the end cover and filter layer are welded by hot melt. There is no adhesive present. The filter core will not cause secondary pollution to the filter separation medium during the whole process of use.
