Blade fan: Features and benefits

When the summer of the thermometer begins to exceed the thirty-degree mark, the only thing you want to do is to find a cool spot in which you can escape from the unbearable heat. A familiar situation, is not it? To escape from the heat can be different. Someone constantly uses cold water, someone goes on vacation and does not get out of the sea, and the hardest part is for those people who work indoors or are forced to stay at home. Therefore, many are probably interested in such a thing as an airless fan. In comparison with an air conditioner its cost is much less, besides it can be put in any place. And the original design of such a device will decorate the interior of any room.

How an airless fan works

The essence of the ideas underlying the development of all household appliances, despite the years, remains the same. All that can give technical progress is only their modification and improvement. And the bezlopastnoy fan is no exception. To his appearance, the cunning device is due to the American inventor James Dyson. It occurred to him to create a device for moving air, which has neither blades, nor any moving parts. How, then, does an airless fan work? The principle of operation of this device was borrowed from a hand dryer, to which we have long since become accustomed. When we put our hands under it, the airflow begins to move with great force and involves the air layers that are from him in the immediate vicinity. The bezlopastny fan in its form represents an aerodynamic ring, which is located on a small stand. Inside the motor is installed. In the very aerodynamic ring, a very narrow slit with a width of only 1.3 mm is arranged. The turbine pushes air into it with great force. Inside the structure, a high pressure is formed, and a mixture of gases begins to exit the gap at high speed. As a result, in front of the center of the ring there is a zone of rarefaction, which draws in the surrounding air.

What is good is an airless fan

The rich color scheme and modern design of such devices allow to choose a model in accordance with any tastes and preferences of customers. The body can be both plastic and chrome. And some models even have built-in lighting. The most important advantages that an airless fan can boast of is a noiseless operation, adjustable blowing speed, a uniform and smooth air movement. The absence of grilles and blades in the body makes cleaning quick and easy, and a low center of gravity gives the device excellent stability. Air supply can be made at different angles, and the presence of the console will surely appeal to those who are used to comfort. Safety is equally important. You can safely leave the fan without fan in the room where children or pets are. All this makes this device very useful.
