1. An air amplifier for directing airflow from a fan assembly, the air amplifier comprising:
an inlet for receiving airflow from the fan assembly; and
an airflow cavity, wherein the airflow cavity is defined by a first wall and a second wall that define an airflow passageway extending towards an exhaust outlet for emitting air;
and wherein a divider body is provided within the airflow passageway, the divider body dividing the airflow passageway into a first exhaust passageway and a second exhaust passageway, wherein the divider body tapers towards the exhaust outlet, and wherein the first exhaust passageway and the second exhaust passageway are equal in width and have a constant width.
