Abstract: A fan assembly for creating an air current is described. The fan assembly includes a nozzle mounted on a base housing a device for creating an air flow through the nozzle. The nozzle includes an interior passage for receiving the air flow from the base, a mouth through which the air flow is emitted, the mouth being defined by facing surfaces of the nozzle, and spacers for spacing apart the facing surfaces of the nozzle. The nozzle extends substantially orthogonally about an axis to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan. The spacers can provide for a reliable, reproducible nozzle of the fan assembly and performance of the fan assembly.

Abstract: A portable fan includes a casing having an air inlet and a first connector, and an air outlet having a second connector. A filter unit includes a third connector, which is substantially the same as the second connector, for co-operating with the first connector to removably connect the filter unit to the casing, a filter which is located upstream from the air inlet when the filter unit is connected to the casing, and a fourth connector, which is substantially the same as the first connector, for co-operating with the second connector to removably connect the air outlet to the filter unit. This can allow the air outlet to be connected either directly to the casing, or to an optional filter unit which is connected to the casing.

Abstract: A portable fan includes a casing having an air inlet, and an air outlet having an interior passage for receiving an air flow, and a mouth for emitting the air flow, the interior passage extending about an opening through which air is drawn by the air flow emitted from the mouth. The fan includes an impeller and a motor for rotating the impeller to generate an air flow between the air inlet and an air outlet which has a static pressure of at least 150 Pa downstream from the impeller. A filter unit is detachably connected to the casing. A filter of the filter unit is located upstream of the air inlet to remove airborne particulates from the air flow before it enters the casing.

Abstract: An external accessory for a portable fan including a base having an air inlet located in a side wall of the base, and an air outlet detachably connectable to the base, the accessory including a high energy particle arrester filter and connectors for detachably connecting the accessory to the fan so that the filter is located upstream from the air inlet of the fan.
