Abstract: A bladeless fan comprising a ring-shaped chamber extending longitudinally and defining a suctioned air passage having a main-flow inlet and a main-flow outlet; a compressed-gas inlet adapted to receive compressed gas and to provide the compressed gas to the ring-shaped chamber; and a proximal row of channels radially distributed about the suctioned air passage. The channels provide a fluid connection for the compressed gas from the ring-shaped chamber to the suctioned air passage thereby generating a pressure differential along the suctioned air passage and forcing a flow of gas from the main-flow inlet to the main-flow outlet.
