A fan assembly is provided and includes a fan body, a motor-driven impeller contained within the fan body, and a filter assembly engaged with the fan body. The fan body can include an air inlet defined by an inlet surface. The motor-driven impeller can generate an airflow. The filter assembly covers part of the inlet surface and may include a filter and a housing for the filter. The housing has a filter retention assembly for releasably retaining the filter in the housing upon actuation of a user interface. When the user interface is actuated, the filter may slide freely along the housing and be released from the housing.

Fan assembly with a removable filter assembly

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.

A nozzle for a fan assembly is described. The nozzle includes a first duct through which a first airflow moves, the first duct having a first outlet for emitting the first airflow. The nozzle further includes a second duct through which a second airflow moves, the second duct having a second outlet for emitting the second airflow. The first and second outlets are arranged such that the first and second airflows collide to generate a combined airflow having a direction defined by the relative flow rates of the first and second airflows. The first duct then includes a portion moveable to vary the flow rate of the first airflow.

Nozzle for a fan assembly

A fan assembly, including a fan body including an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly is arranged to removably engage with the fan body and to cover at least a portion of the inlet surface when engaged with the fan body. The filter assembly includes a filter and a housing for the filter, the housing being provided with a filter retention assembly for releasably retaining the filter in the housing, and a user interface for actuating the filter retention assembly to release the filter from the housing. Upon actuation of the filter retention assembly via the user interface, the filter is free to slide relative to the housing. Preferably, the user interface is positioned on the housing.
