Abstract
A nozzle for a fan assembly includes an air inlet, a plurality of air outlets, and an annular casing having an annular inner wall defining a bore through which air from outside the nozzle is drawn by air emitted from the air outlets and an outer wall extending about the inner wall. The annular casing includes an air passage for conveying air to the air outlets. The air passage has an inlet section located between the inner wall and the outer wall and extending about the bore of the nozzle, and a plurality of outlet sections each extending across the bore for conveying air to a respective air outlet. To achieve an even air pressure at each end of each of the outlet sections, the inlet section of the air passage is arranged to convey air to each end of each of the outlet sections.
