摘要： An open flow fluid filter has a pleated main filter element having a plurality of pleats in a closed loop having an outer perimeter defined by a plurality of outer pleat tips, and an inner perimeter defined by a plurality of inner pleat tips. The loop has a hollow interior extending along an axis. Fluid to be filtered flows through the main filter element from an upstream dirty side to a downstream clean side, and flows axially in the hollow interior. The main filter element has an axial flow passage extending along the axis and circumscribing the hollow interior and has a flow perimeter greater than the inner perimeter. A safety filter element downstream of the main filter element filters both the axial flow in the hollow interior and additional flow between the flow perimeter and the inner perimeter. A filter with additional flow is also provided.

摘要： A filter element (202, 250) includes pleated filter media (26) having a plurality of pleats (28) in a closed annular loop having an outer perimeter (30) defined by a plurality of outer pleat tips (32), an inner perimeter (34) defined by a plurality of inner pleat tips (36), the loop having a hollow interior (38) extending along an axis (40), wherein fluid to be filtered flows laterally through the filter media and flows axially in the hollow interior (38). The filter element has an axial flow passage (56a) along the axis (40) and circumscribing the hollow interior (38) and has a flow perimeter (218) greater than the inner perimeter (34) of the filter element defined by the inner pleat tips (36), and in the preferred embodiment substantially the same as the outer perimeter (30) defined by the outer pleat tips (32), to provide axial flow (58) through the hollow interior (38) and additional axial flow (59 and 59a) through the axial ends (68) of the pleats.

摘要： A filter (10) has a housing (12) extending along an axis (18) between first and second axial ends (20 and 22), and has a closed loop primary filter element (24) extending axially in the housing, and a closed loop safety filter element (48) in the hollow interior (30) of the primary filter element. A detent member (60) engages and retains the end cap (54) of the safety filter element independently of the primary filter element to retain the safety filter element in housing upon removal of the primary filter element from the housing.
