A compressor assembly includes an impeller rotatable about a central axis, and a seal assembly. The seal assembly includes a labyrinth seal defining a seal interface with a sealing element of the impeller, and a seal support ring into which the labyrinth seal is installed. The seal support includes a deflector ramp fluidly downstream of the seal interface. The deflector ramp is configured to turn an airflow leaking through the seal interface radially inwardly toward the central axis.
