A filter system for intake air of an internal combustion engine has a housing with a cover. A filter element is arranged in the housing. An inlet feeds a medium to be filtered into the housing and an outlet discharges the medium from the housing. The filter element has a filter body with first end face and opposite second end face. The filter element has an open first end plate at the first end face and a second end plate at the second end face. A support tube is arranged concentrically about a longitudinal axis in the housing and attached with a first end to the housing. The support tube is arranged in the interior of the filter element and radially supports the filter body. The second end plate rests on the second end of the support tube and on an inner cover contour of the cover with anti-rotation action.

A filter includes a plurality of annular filter elements arranged in axially staggered relation. An axial flow path includes a plurality of flow path segments, some being filtered by a respective filter element, and others bypassing a respective filter element. Various combinations are provided.

Industrial vacuum systems are disclosed, as are filter chambers for industrial vacuum systems and other filtration applications. The filter chambers in these systems use two distinct types of filtering elements within a single chamber, arranging the filter elements such that air cannot pass through a secondary filter element until the air has first passed through and been filtered by a number of primary filter elements. The airflow within the filter chamber may be essentially vertical, and the secondary filter element may be positioned above the primary filter elements. The filter chamber may also include an agitation system for cleaning the filtering elements. The agitation system may be constructed such that it can operate while the system is in use.

A segmented air filtration element is provided. The segmented air filtration element includes a center tube defining a central axis and an inner passage therein. The center tube includes a plurality of ribs extending along the central axis and spaced apart from one another. A plurality of segmenting surfaces is attached to the center tube in a radial arrangement with respect to the central axis. The plurality of segmenting surfaces is configured to accommodate a plurality of filter media therebetween such that each of the plurality of filter media is selectively replaceable therefrom.

An air cleaner includes a first blowing device having a first inlet and a first outlet, a second blowing device disposed above the first blowing device and having a second inlet, and a partition plate disposed between the first outlet and the second blowing device. The first blowing device includes a case forming the first inlet and opened in an upper side, a discharge guide device disposed in the opened upper side of the case and forming the first outlet, a first fan disposed inside the case and forming an air flow from the first inlet to the first outlet, and a splitter disposed between the partition plate and a discharge guide device and extending upward from the discharge guide device in a radial direction of the discharge guide device to separate an air flow discharged from the first outlet and guide the air flow in the radially outward direction.

A filter for compressed air systems is provided. The filter includes a filter housing with a filter therein between an air inlet and an air outlet. Compressed air flowing between the air inlet and the air outlet passes through the filter housing and the filter element. A base is removably fastened to the filter housing which may be separated from the filter housing to allow the filter element to be removed and replaced.
