CYLINDRICAL DEPTH FILTER FOR FILTERING FLUID AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A cylindrical core filter for filtering liquid and a manufacturing method thereof are provided to gradually increase porosity of the filter according to fineness of non-woven fabric filter media without a separated support. CONSTITUTION: A cylindrical core filter for filtering liquid includes non-woven fabric filter media and a support. The woven fabric filter media is thermally bonded on the support. The porosity of non-woven fabric is gradually increased according to fineness of the non-woven fabric filter media without a separated support. The non-woven fabric filter media is formed in a range of 1/10 ~ 10/10 of the diameter of a core filter.
