A fan including a driving motor, a plurality of blades which are connected to the driving motor to rotate, and a housing having a housing main body to accommodate the driving motor and the blades, an air inhaler that is provided in the housing main body to inhale air toward the plurality of blades, an axial air discharger that is provided in a rotational axis direction of the plurality of blades and a radial air discharger that is provided in a radial direction substantially perpendicular to the rotational axis. The fan generates air flow both in the axial and radial directions, thereby increasing the number of directions in which air flows, reducing the number of fans to be used, minimizing an installation space required, and reducing noise generated by the fans.
