A filtration system is provided that includes a gearbox positioned in a geared turbofan engine. The system further includes an auxiliary lubrication system positioned in the geared turbofan engine and in fluid communication with the gearbox. The auxiliary lubrication system includes an auxiliary reservoir, an auxiliary pump in fluid communication with the auxiliary reservoir, an auxiliary return line extending between the gearbox and the auxiliary reservoir, the auxiliary return line configured to transport a lubricant from the gearbox to the auxiliary reservoir, and an auxiliary supply line extending between the auxiliary pump and the gearbox, the auxiliary supply line configured to transport the lubricant from the auxiliary pump to the gearbox. The system further includes a non-removable filter positioned in the auxiliary lubrication system. The non-removable filter is configured to prevent or limit debris that is suspended in the lubricant from flowing into the gearbox and/or the auxiliary pump.

A self-cleaning conduit for a hydrocarbon fluid. The conduit includes a tube and a mesh. The tube has an interior surface defining a flow passage for the hydrocarbon fluid. The mesh is positioned within the flow passage to abut the interior surface and movable along the interior surface to break-up deposits on the interior surface. The mesh is characterized by a mesh activation parameter (MAP) from one ten thousandths to six tenths.
