A gas turbine engine with a geared architecture includes a multiple of bearing compartments and at least one carbon seal that seals at least one side of each of the multiple of bearing compartments. Aircraft gas turbine engines include an oil system to supply oil to various components such as bearings that are typically contained within bearing compartments. All gas turbine engines ingest some air from the gas path in regular operation due to the pressure differential between the gas path and bearing compartments. |
