Abstract
A vertical lighting vaneless inverter fan comprises a body, a blast system, an air supply column, a lighting device and a sound-reducing structure. The blast system is mounted in the inner chamber of body. The air supply column is installed on the top of body. The blast system supplies air to the air supply column, the airflow is jetted from the air supply column. The impeller is located above the motor. When the blast system is installed in the inner chamber of body case, the impeller corresponds to the bottom of air outlet, so that the wind can be delivered through the air outlet directly.
