    • A dual pleated air filter according to the present disclosure may include two or more generally parallel, pleated filter elements layered perpendicular to the influent air stream and having the pleats of adjacent filter elements oriented orthogonally. Within each pleated filter element are an influent mesh layer and a corresponding effluent mesh layer for supporting filter media and one or more layers of filter media are located between the influent and the effluent mesh layers. The relative orientation of pleats of adjacent elements may range from parallel to perpendicular.
    • 根据本公开的双重褶式空气过滤器可以包括垂直于流入空气流分层并且具有正交定向的相邻过滤元件的褶皱的两个或更多个大致平行的褶皱过滤元件。 在每个褶状过滤元件内,流入物网层和用于支撑过滤介质的相应流出物网层和一个或多个过滤介质层位于流入物和流出物网层之间。 相邻元件的褶皱的相对取向可以在平行于垂直的范围内。
