On a hot summer day, is the constant hum of the fan at home making you unbearable? If so, French designer Stéphane Thirouin may already have a solution: the powerful but very quiet indoor fan Williwaw. It is understood that this product promoted by the designer as the best fan is completed with the help of 3D printing technology . The ambitious designer is currently on the crowdfunding platform with his products, with a crowdfunding target of 1 million euros.

It is reported that Thirouin is an experienced independent designer. He found that even the best fan in the world will produce a lot of noise, and it can't be universal, and it can't produce enough wind that he likes. This idea. He explained: "I like useful, durable and pleasing objects." So he began to build a fan that would satisfy him. After a lot of research and development (involving many 3D models and 3D printed prototypes), Thirouin finally designed the fan Williwaw with nine fan blades inspired by aviation technology.

So, what is special about Williwaw? According to the designer, the fan blade was designed from a professional aerodynamic engineer who helped Thirouin find the best blade design for his fan. This design, combined with a brushless, electrically controlled motor, results in a machine that is stronger and quieter than all fans on the market. If you want to know the exact number, at a distance of 2 meters, for every 2000 liters of air, Williwaw's noise is only 50dBA (3dBA less than the leading brand of fan).

In addition, the fan's versatility is also outstanding. In other words, the fan's swing angle can be adjusted from 20 to 270 degrees, you can choose to ventilate a complete room, or you can only vent a specific part. The head of the fan can even be rotated upwards. Therefore, it can also be used as a ceiling fan to make the air go slow and convective. As for energy consumption, the fan's motor is only 45 watts at full power.

In addition, the Williwaw fan has some interesting features, including a handy app that can help you visualize your home space before buying. The designer also provides a 3D file of each plastic part so that if any part is damaged, you can print it in 3D (in addition to the seller's basic 2 year warranty).

On the crowdfunding platform, the innovative indoor fan from Thirouin starts at €350 and is available in 220/240 V or 100/127 V. If crowdfunding is successful, supporters may receive their fans in June 2017, and Williwaw's delivery range is currently only within the EU.
