排气薄膜过滤器及其制备方法
摘要：
本发明涉及一种薄膜过滤器的制备方法，其包含以下步骤：通过亲水性过滤元件的纤维束的至少第一端，将所述纤维束固定在被称为底部元件的外壳部件中，使所述亲水性过滤元件的第一端朝所述外壳部件的第一侧开口，并且所述亲水性过滤元件延伸到所述外壳部件的相对侧；以及随后提供至少一个不透水但透气的元件，特别是一种疏水性过滤元件。
摘要（英）：

The method comprises steps of (a) fixing a bundle of hydrophilic filter elements by at least a first end to a housing part that is called as a bottom element, such that the first end of the hydrophilic filter elements is open towards a first side of the housing part and the hydrophilic filter elements extend on the opposite side of the housing part; and (b) subsequently providing at least one watertight and air-permeable element, particularly a hydrophobic filter element.
