An air amplifier (3, fig.1) nozzle containing an air inlet, receiving air from a fan assembly (5, fig. 1), leading to an airflow cavity 207 comprising a first wall 211 and secondary wall 213 which define an airflow passageway 215, extending towards an air exhaust outlet 217. A divider structure 221 is placed within the airflow passageway, dividing the airflow corridor into a first exhaust passageway 223 and a second exhaust passageway 225, the shape of the divider structure narrows towards the exhaust outlet. The amplifier may include a lip 227 at or towards a front edge of the first wall to partially inhibit airflow in the first exhaust passage. The divider structure may have a hollow or solid body, be wedge, diamond or V-shaped. A heating or cooling element can be included within the airflow cavity to provide warm or cold air.
