FILTER DEVICE AND FILTER ELEMENT

摘要

A filter apparatus is composed such that a filter element is housed and held in a cylindrical housing, which has one side open, so as to separate a flow-in side and a flow-out side of a fluid from each other. A filter element is basically composed of a filter body that is made by laminating and arranging plural sheet-like filter media with a gap. The filter element is formed by shaping the filter body into a pleated shape, and retaining the pleated shape.
