An air gasper knob system for an overhead Passenger Service Unit (PSU) includes an annular gasper knob of a UV transparent material. The annular gasper knob defines an air passage therethrough, and extends about the air passage from a first annular end face to a second annular end face. The system also includes a UV illuminator mounted to the gasper knob, oriented to transmit UV illumination through the UV transparent material to sanitize exterior surfaces of the gasper knob. A method of sanitizing an air gasper knob comprises illuminating a gasper knob in an overhead PSU using UV illumination to destroy infectious agents on surfaces of the gasper knob.

An environmental control system includes an ambient air conduit and a bleed air conduit, an electric compressor connected to the ambient air conduit and a mechanical compressor connected to the electric compressor. The electric compressor is supported for rotation independent of the mechanical compressor. A turbine is operatively connected to the mechanical compressor, the turbine connected to both the ambient air conduit and the bleed air conduit to provide conditioned air to a conditioned air conduit. Computer program products and methods of providing conditioned air to conditioned air loads are also described.
