The SQW high-flow pleated filter element has a diameter of 6.5in/165mm, uses polypropylene or glass fiber membrane as the filter material, and has a central rod inside, which is suitable for liquid flow from outside to inside. The large outer diameter design of the filter element increases the effective filtering area, which can greatly reduce the number of filter elements and the size of the shell under the same flow rate application, thus greatly saving the production cost.
