Abstract The present invention discloses a multi-stacked circular plate fan provided with blades. The fan is formed by stacking a multiplicity of annular circular plates while maintaining a desired gap therebetween and is characterized in that multiplicity of blades are interposed between the annular circular plates and at least either of the trailing edge or the leading edge of the blade is positioned a predetermined distance to the inside from the outer periphery of the annular circular plate or a predetermined distance to the outside from the inner periphery of the annular circular plate. Due to the laminar flow effect caused by the circular plates, the turbulent flow which is produced at the ends of the blade by peeling-off of air can be effectively suppressed and the outlet velocity distortion at the outer periphery of the annular circular plate can be suppressed so that the turbulent noise and the interference noise are reduced thus providing a silent air-expelling operation.
