Famous for its ventilateur and other electronic products, the James Dyson Company in 2009 created a wave in the market with its air multiplier technology. This is an extraordinary technology that resembles a few inches deep circular tube on a pedestal, with no visible blades! The device has no moving parts, and, at the first glance, you think that the gadget is lifeless. But, as soon as you switch on the fan, a gentle breeze flows through the tube and amazes you.
These are modern fans that awe you with their no-blade, fine-breeze technology. A lot of science comes to the scene in bladeless ventilateur. The device contains an electric motor that sucks in air and transfers it to the circular tube. The air enters a slit in the tube, which generates a basic flow. This is the breeze that you feel when you’re in front of the fans using this technology. The company claims that this technology gushes out about 15 times more air than that sucked in by the motor. Also, the airflow is uniform. Because of the absence of rotating blades, you feel no short blasts of air.
Where Are The Blades?
To tell you the truth, this Dyson technology is not completely bladeless. The blades are there, but invisible! The pedestal conceals them. The device actually encompasses nine blades aligned asymmetrically. The motor rotates them to suck air into the ventilateur. The company claims that the “invisible” blades have the power to suck in about 5.28 gallons of air (about 20 liters) each second. The insides of the tube are hollow and allow smooth flow of the air, which then gushes into the slits positioned behind the fan.
Now the laws of physics come to play. As the air passes through the slits and out at the frontal part of the fan, the air at the back of the fan gets sucked in the tube at the same time. This phenomenon is known as inducement. In simpler words, the air compelled by the motor “induces” the air at the back of the fan to follow it.
During inducement, the air at the fan edges also flows in the direction of the blowing breeze. This phenomenon is known as entrainment. It’s during these two phenomena that the airflow increases by 15 times as claimed by Dyson.
When the technology was launched, the company had introduced air multiplier vacuum cleaners and ventilateur in two sizes. The bigger model features a 12-inch diameter fan, whereas the smaller model has a fan of ten-inch diameter. The devices, whether having small or big fans, came with a price tag. But, the air efficiency nullifies the effect of dollars that you have to spend in buying them! On top of it, the sleek design of the devices equipped with such amazing technology makes you almost forget the price.
So, if you’re looking for a ventilateur with a calm functioning and a neat and elegant look, choose the air multiplier technology. The “invisible” blades, in a way, render a mystical element to the device. You see only a slender tube with gentle breeze coming out of it!
