Abstract: An attachment that attaches to the trailing edge of a ceiling fan blade has a curved and flexible dam that curves rearwardly from the trailing edge and downwardly from a lower surface of the fan blade. When the ceiling fan is operational and fan blades are rotating, the curved dam interacts with the air moved by the fan blade and directs the air in a downwardly direction toward the occupants of the room where the fan is installed. At increased fan speeds, the dam flattens out, decreasing any additional load placed on the motor of the fan by the downwardly curved dam. One attachment is attached to each of the blades of the fan.
