Abstract: A pre-cleaner may include a plurality of spin tubes arranged side-by-side to form a row. Each spin tube may include a longitudinal axis, an inlet at a first end, and an outlet at a second end. The pre-cleaner may also include a manifold enveloping the outlets of the plurality of spin tubes and configured to receive and direct dust away from the outlets. The manifold may include a cover portion extending along and adjacent the row of spin tubes at a position along the longitudinal axis that is between the respective outlets and first ends of the spin tubes. The manifold may also include a trough extending along the row of spin tubes and defining a collection area that is arranged at a position along the longitudinal axis that is beyond the second ends of the spin tubes. A method of dust removal is also described.

Abstract: A filter element includes a bottom open end joined to a center tube opposite the top open end. The bottom open end defines a radially outer surface and a radially inner surface that is in communication with the central reservoir of the filter element. A first locking feature is disposed proximate to the bottom open end. The locking feature includes an entrance slot that is disposed on the radially inner surface of the center tube extending axially from the bottom open end. A similar or identical second locking feature is disposed proximate to the top open end.

Abstract: An endcap for a filter element includes an annular plate member disposed adjacent an axial end surface of an annular filter medium of the filter element. A radially outer annular flange projects axially from a surface of the annular plate member. The radially outer annular flange includes a winglet feature extending radially outwardly in a cantilever fashion from an outer circumferential surface of the radially outer annular flange in a direction opposite to a direction in which the filter element is rotated during installation into a filter base of a filter system, with the winglet feature deflecting toward the outer circumferential surface of the radially outer annular flange through contact with a wedge-shaped protrusion projecting radially inwardly from an inner circumference of the filter base as the filter element is rotatably installed into the filter base, and springing back to its undeflected configuration after passing the wedge-shaped protrusion.

Abstract: A diesel engine aftertreatment system is disclosed. The aftertreatment system includes a diesel exhaust fluid (DEF) injection system including a selective catalytic reduction (SCR) device, a DEF tank connected to the SCR device, a DEF injection device installed in the tank, and an integrated grommet filter. The integrated grommet filter includes a grommet having a top gasket portion and a bottom cylindrical skirt portion. The cylindrical skirt portion is integrally connected to a sock filter. In an embodiment, the integral connection between the skirt portion and the sock filter includes an overlap and stitching. In an embodiment, the gasket is a star shaped gasket.

Abstract: A filter module for filtering fuel in an engine system includes a primary filter, a secondary filter, and a module housing. A drain valve is movable between a closed position blocking a drain port in the module housing, and an open position. A service valve assembly is positioned at least partially within a cross passage in the module housing and adjustable from a closed configuration blocking a primary-side fuel passage from a secondary-side fuel passage in the module housing, to an open configuration, to drain fluids from the filter module by way of the single drain port.

Abstract: A center tube and a central fluid supply tube combination includes a center tube body defining a longitudinal length, and a central reservoir. The center tube also includes an apertured annular wall extending axially the majority of the longitudinal length, and a first annular solid wall extending axially from the apertured annular wall. A central fluid supply tube is disposed in the central reservoir, and includes a second annular solid wall that is radially surrounded by the apertured annular wall of the center tube. The second annular solid wall defines a supply passage with a fully circular flow flux.

Abstract: A method of assembling a canister filter system includes inserting a first filter component into a second filter component, and continuing the insertion until a first tab of either the first filter component or the second filter component contacts the other of the first filter component and the second filter component.

Abstract: An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and an apertured connecting portion that extends radially outwardly from the mounting portion to the sealing portion.

Abstract: A pedestal for use with a canister filter system and a filter element for positioning and retaining the filter element in the canister filter system includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. Also, the pedestal includes an annular wall that terminates at a bottom free end, and that defines a slot that extends axially upwardly and circumferentially from the bottom free end. A flow aperture extends through the annular wall that is disposed axially above the slot.
