Abstract (en)
A motorised impeller assembly for delivering an air flow, the assembly comprising: a first, main air flow path having an inlet and an outlet and through which a main air flow is delivered; a second, ancillary air flow path having an inlet and an outlet and through which an ancillary air flow is delivered; an impeller which is operable to deliver the air flows through the main and ancillary air flow paths; and a motor unit which comprises a drive motor for driving the impeller, and a sensor for sensing a characteristic of the ancillary air flow as delivered through the ancillary air flow path in operation of the impeller, which characteristic is representative of a flow rate of the main air flow as delivered through the main air flow path and enables control of the delivered air flow.
