An electric fan mounted overhead for universal adjustment of the air flow direction. A mounting plate clamped to an overhead beam carries a sleeve that rotatively receives a vertical column. The lower end of the column pivotally connects with a mounting arm which carries the fan. A rotation motor can rotationally adjust the column to adjust the lateral direction in which the fan faces. A linear actuator pivots the mounting arm up and down to adjust the tilt angle of the fan.
