Abstract
A filter element is constructed such that a filter material having a corrugated sectional surface is formed in the shape of a cylindrical housing, and an upper opening portion of the cylindrical housing is kept closed, and an lower opening portion is connected to an air suction duct. A row of hills and valleys of the corrugated sectional surface is formed with a certain front angle relative to the wall surface of the cylindrical casing.
Claims5
an air filter comprising a sheet of pleated first air filtering material having a generally cylindrical shape with a closed top and an open bottom for providing filtered air through said open bottom in which pleats in said material are angled tangentially relative to a longitudinal axis of said cylindrical shape for deflecting filtered air;
- a funnel having a first, larger end for closing said closed top and a second, smaller end which extends into said cylindrical shape for deflecting filtered air towards said open bottom,
- the combination of said angled pleats and said funnel for deflecting air inside said cylindrical shape in a laminar and generally swirl-free flow of filtered air through said open bottom,
- wherein said second end of said funnel has a truncated end for filtering air.
