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 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.

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.
