An air cycle machine (400) comprises rotating components that include a fan, a compressor, and a first turbine. The air cycle machine (400) also includes a cooling airflow path (406) that receives cooling air from a cooling air source, directs the cooling air to an air-cooled bearing (406,408,412,414) for at least one of the rotating components, and discharges the cooling air. The airflow path (406) is isolated from an inlet (422) of the compressor by a seal member (260), and the airflow path (406) is configured to maintain pressure at the seal member (420) above a pressure at the compressor inlet (422).
