Abstract:
A rotor 20 having several impellers 21 interleaved with a multi-stage stator 30 pumps ambient air through each stage in a path that flows radially outward through impeller vanes 27 against a stator wall 32 where the air is retroverted and directed radially inward through a stator passageway 36 to the next rotor impeller 21. Flow through each stage increases air temperature so that the output air, in addition to being blown forcibly enough to pass through ductwork, is warmed enough to afford space heating.
