"Inflatable Air Blower" structural principle: no leaf fan works as follows: 40-watt electric motor with the base of the 33 liters of air per second suction fan base inside the largest accelerator through the cyclone, air velocity is increased about 16 times through no leaves "Inflatable Air Blower" lip ring around the inner fan head, which surrounds the force driving the fan head followed them into the air near the fan head, and the speed of 405 liters per second blown outward. The Air Multiplier blade less "Inflatable Air Blower" size with variable frequency speed regulating device to facilitate the user to adjust the size of the wind speed of the actual situation, even increasing the amount of wind, not impulse voltage, low power consumption, an ordinary fan energy consumption by half .
