An air mass induction device, such as a bladeless fan, comprises a housing 2 having a leading edge 4 and a trailing edge 6 extending in the longitudinal direction, where the housing comprises two opposing external surfaces 8a and 8b which taper towards the trailing edge 6, at least two nozzles 10a and 10b extending in the longitudinal direction of the housing such that at least one nozzle is associated with each opposing external surface and is arranged to direct air received from within the housing over the respective opposing external surface towards the trailing edge, to induce air from outside the housing to flow in the direction of the trailing edge. Preferably the housing comprises at least one internal chamber 12 in fluid communication with at least each nozzle. A method for air ventilation is also claimed. |
