An air cycle machine (100) includes a housing (110) having an exterior wall (132) and an interior wall (134), a scavenging turbine (120) supported for rotation within the housing, and an ambient air fan (122). The ambient air fan is supported for rotation within the housing and is operably associated with the scavenging turbine. The interior wall defines therethrough a turbine-fan port (146) that fluidly couples the ambient air fan to the scavenging turbine for communication of an overboard air flow to an ambient air flow without external ducting. Environmental control systems (102) and methods (200) of flowing fluid through air cycle machines are also described.
