Leaf fan, also known as "air double machine", this new invention than in the general fans reduce energy consumption by 30 percent, but also because it abandoned the traditional fan blade parts, innovation and a fan of the leather type, so that the fan change safer, more energy efficient, more environmentally friendly, therefore, no blades fans the U.S. technology magazine as one of the world's top ten inventions for 2009. 
 Leaf fan works as follows 
 Leaf fan works as follows: the base with 40-watt electric motor per second will be 33 liters of the air intake fan inside the base, through the cyclone accelerator, air velocity was increased about 16 times through within the leaf fan fan head ring around the lips, around the force to drive the air near the fan head and followed them into the fan header, and 405 liters per second speed blow out. Multiplier of this air leaves the fan with variable frequency wind speed size adjustment device, user adjust the size of the wind speed according to the actual situation, uniform air flow increase will not impact voltage, low energy consumption, is the ordinary fan energy consumption by half. In addition, because the fan does not carry a fan, for the curious nature of children is not harmful, but also easier to clean than ordinary air-conditioning and fan. It uses the latest fluid power engineering, the flow of air through high efficiency brushless motor 15-fold increase in release rate of 118 gallons per second, or 1580CFM wind. 

 Characteristics of non-leaf fan 
 Ye fan the biggest difference is that it does not "leaves" of the traditional fan! Leaf fan jet engines and automotive turbo technology, the inhaled air through the bottom of the suction hole, hidden inside of the ring the edge of an impeller put air spray in a circular path, and ultimately form a intermittent flow of cold air. Important that this air flow more smoothly than the average fan wind. The amount of air it produces the equivalent of the current market performance of the best fan. Because there is no fan piece to 'cut' air, you will not feel the shock and excitement. By continuous air flow to make you feel cool. This non-leaf fan at the same time with the adjustment device of the inverter size of wind speed, user-friendly according to the size of the actual situation to adjust the wind speed, air flow uniformly increasing, not the impulse voltage, low energy consumption, is the ordinary fan energy consumption by half. Because no blades, this fan not only look cool, but is more secure than traditional fans, shaking his head at the same time, wind speed control function is also comparable with the latter. 
 No leaf fan features:
