The final shape of the "Blower Fan" is the tip of a thin, intermediate thick, as the leaves are generally unique blade shape. This spiral shape using the same method of determining jet stream discharged by forming a stable swirling flow, reduce operating noise. Such development blower than in the past about the volume reduced by 15%. Further, in the same amount of wind, the Working noise reduced by approximately 4dB, reducing power consumption by about 20%. New fan volume decreased by 15% to achieve quietness, compared with previous products, the fan diameters from 155mm down to 128mm, thickness reduced 20mm. Volume was reduced by approximately 15%. The same amount of wind, the operating noise of approximately 4dB, power consumption is reduced by approximately 20%.
