Abstract: A propeller fan assembly that generates lower sound pressure during operation and minimizes blade deflection without sacrificing performance. The blades of the propeller fan comprise silencer seeds located on the suction side of the blades, closer to the leading edge and the tip of the blades. The silencer seeds are sized in increasing face area and form an array with areas increasing with each row. The propeller fan assembly also comprises a dual hub comprising more than one circumferential layer concentric with the axial fan's hub. Multiple circumferential layers provide significant additional support to the blades during operation. This minimizes blade deflection and preserves the performance of the blade as intended. The overall fan and orifice assembly uses a unique assembly method that allows for wide flexibility and permits use of motors of different types and sizes seamlessly with this propeller fan assembly.
