"220V AC Cooling Fan" fans have been using a large motor, short blade structure. High noise, low air volume has been plagued by the end user. In view of this situation, a change in the traditional motor structure. "220V AC Cooling Fan" took the lead with a long blade, small motor structure, developed a low-noise structure. Since the blade length, so at low wind speed conditions can provide the amount. Since the case of the same amount of wind speed is reduced by 30%, the noise is greatly reduced. "220V AC Cooling Fan" blower motor structure due to the small, does not produce high pressure. Therefore, the requirements for a small amount of wind, air pressure requirements for large applications will not apply.
