Abstract:
A fan assembly includes a nozzle having a plurality of air inlets, a plurality of air outlets, a first air flow path and a second air flow path. Each air flow path extends from at least one of the air inlets to at least one of the air outlets. The nozzle defines a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle. The fan assembly also includes a first user-operable system for generating a first air flow along the first air flow path, and a second user-operable system, different from the first user-operable system, for generating a second air flow along the second air flow path. Through user selection of one or both of these two systems, at least one of two different air flows can be emitted from the nozzle, each having a respective flow profile or other characteristic.
