Abstract
A fan assembly includes an annular nozzle and a system for creating a primary air flow. The nozzle includes an outer wall and an inner wall surrounded by the outer wall, the inner wall defining a bore having a bore axis. The nozzle also includes an interior passage located between the inner and outer walls, and extending about the bore axis for receiving an air flow, and an air outlet located at or towards the front of the nozzle for emitting the air flow. The nozzle is configured to emit the air flow through the air outlet in a direction extending away from the bore axis.
