Would you like to know more about bladeless fans? What are bladeless fans? Perhaps the best way to explain what they are is to start with bladed fans. Everyone can probably close their eyes and see a variety of traditional fans. Ceiling fans, box fans and the old standby desk fan. They are all very different, but all have one thing in common: Fan blades spin, creating the air flow. The big problem with bladed fans is that the possibility exists, no matter how remote in some cases, that fingers or some other object can accidently get into the fan blades, with occasional drastic results. That is one reason why bladeless fans were created. Bladeless fans are stylish unto themselves because they do not resemble the traditional fan styles in most cases. So, what are bladeless fans? Bladeless fans are fans which eschew the traditional fan blades for another way of creating and pushing a useable stream of air. There are several types of bladeless fans and this article will try to illustrate the most popular types.
- Tower Fan The tower fan uses fairly old technology that create a flow of air. It uses a circular device most commonly known as a "squirrel cage" to create airflow. This is the same device used in most forced air furnaces. This is a small, round device with slots along its outer circumference. This device is spun by an electric motor, drawing in air from an input duct and blowing it out an output duct. Many manufacturers make this type of bladeless fan.
- Dyson Type Bladeless Fan This is the newest type of bladeless fan and probably the most stylish and unique looking of them. Several companies now make this type of fan, but Dyson was the first, which is why this article lumps them under the name Dyson type. This fan uses an impeller in the base of the fan, still fairly old technology itself, to draw air into the unit. The air is then pushed out through a thin slot along the inside edge of the large round or oval top unit. The escaping air is pushed out over an airfoil shape, creating its direction and pulling additional air from behind it into the flow. This moving flow then "grabs" air from the surroundings as it passes, "multiplying" as Dyson calls it, the air flow towards where ever it is aimed. That is how this new Dyson type bladeless fan works. It is an interesting design which is both stylish and effective.
That is what bladeless fans are and how they work. Do they work better? Maybe, maybe not. Bladeless fans do, however, make a good replacement or addition to the more traditional fans. Bladeless fans by their design can be put in places where you need a taller and smaller footprint or where you have things which could be put into the fan blades and damaged, like fingers.
