Abstract: A fan assembly, including a fan body including first and second retention assemblies and an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly attached to the fan body includes one or more flexible filter media, a first engagement element positioned at first edge of the filter media, and a second engagement element positioned at a second, opposite edge of the filter media. The filter assembly is furlable, and the first and second engagement elements releasably engage with the respective first and second retention assemblies of the fan body to retain the filter assembly tautly over the inlet surface in an at least partially unfurled state, such that, in use, airflow drawn through the air inlet by the motor-driven impeller is drawn through the filter media. The fan body is cylindrical in shape and the filter assembly wraps around substantially all the fan body.

Abstract: There is provided a fan assembly comprising a motor-driven impeller for creating an airflow and a nozzle comprising a first air outlet. The nozzle defines a bore through which air from outside the fan assembly is drawn by any portion of the airflow that is emitted from the first outlet and which combines with the airflow emitted from the first air outlet to produce an amplified airflow. The fan assembly further comprises a second air outlet arranged such that any portion of the airflow that is emitted from the second air outlet does not draw air through the bore defined by the nozzle thereby producing a non-amplified airflow.

Abstract: There is provided a fan assembly including an air flow generator that is arranged to generate an air flow through the fan assembly, and a nozzle arranged to emit the air flow from the fan assembly. The nozzle includes a nozzle body and a plurality of steerable air outlets that are each arranged to emit a portion of the air flow, wherein the plurality of steerable air outlets are arranged to be independently rotated relative to the nozzle body.
