Abstract

PURPOSE:To provide an impeller which by itself can blast obliquely with a conical disk ring opening backwards adjacent the rear edge side of blade to intensify radial differential pressure rather than axial differential pressure in addition to the action of centrifugal fan. CONSTITUTION:A propeller fan 2 is provided on the rear edge 4b of blade 4 with a disk ring 5, and a cylindrical boss 3a larger than a fan motor 12 is disposed to provide a proper gap between it-self and the dimension F of the inner diameter of the disk ring 5. Thus the radial differential pressure is balanced with the axial one by aid of the action of centrifugal fan to be directed obliquely. Also in this case, sicne air fluid d sucked from the central portion is interposed between the disk ring 5 and air C sucked from the outer periphery, the contact of the air C with the disk ring 5 is reduced such that the air C is discharged obliquely circumferentially with small loss and high efficiency.
