Abstract
A ram air fan has a fan impeller and a motor. The impeller and motor are mounted within a housing. An inlet header delivers air to an inlet for the fan. An air supply system delivers air from an internal cavity of the inlet header to the motor and air bearings. The air supply system includes a conduit extending through the housing. A connection from the conduit extends from a J-shaped tube mounted within the inlet header. The J-shaped tube extends to a remote end, with a perforated member positioned on the remote end.
