Lubricant filter system, aircraft engine, and method of operating a lubricant system

An aircraft engine comprising:

• a rotary assembly supported by bearings, and a lubricant system operable to circulate a lubricant to and from the bearings, the lubricant system including a lubricant filter system, the lubricant filter system having:
• a first lubricant filter having a first inlet and a first outlet;
• a second lubricant filter having a second inlet and a second outlet;
• an inlet conduit fluidly connected to the first and second lubricant filters via a first and a second inlet branch, the first inlet branch fluidly connecting the inlet conduit to the first inlet of the first lubricant filter, the second inlet branch fluidly connecting the inlet conduit to the second inlet of the second lubricant filter;
• an outlet conduit fluidly connected to the first and second lubricant filters via a first and a second outlet branch, the first outlet branch fluidly connecting the first outlet of the first lubricant filter to the outlet conduit, the second outlet branch fluidly connecting the second outlet of the second lubricant filter to the outlet conduit;
• a bypass conduit fluidly connecting the inlet conduit to the outlet conduit;
• and
• a bypass valve controlling fluid passage through the bypass conduit:
• further comprising a manifold generally having a triangular prism shape with three transversal faces connecting two end faces, wherein the first lubricant filter is mounted to a first one of the transversal faces, the second lubricant filter is mounted to a second one of the transversal faces, the inlet conduit extends into the manifold from a first one of the two end faces, and the outlet conduit extends into the manifold from a second one of the two end faces.
