Every day there are more and more new devices that are created with the aim of making human life easier. One of these is the bladeless fan. This unit is an innovative product and belongs to climate control devices. It turned out that buyers appreciated the appearance of this device on the market because it is safe, economical and easy to use. In this article we will look at how a fan without blades works, its types, advantages and disadvantages.
The principle of operation of a fan without blades
The design of these devices does not give a complete picture of how it works. Seemingly simple design: a ring is attached to the delivery, through which a powerful air flow passes. Let's take a look at the principle of a fan without blades.
Air passes through the air intake and exits from the back at high speed. The aerodynamic design creates low pressure in order to roll the inlet air currents. The turbine built into the footrest creates a fast air flow at the outlet. This unusual design makes it significantly more efficient than a fan with blades.
This device is safe because it has no rotating elements, so you can feel free to leave it where children can see it. If there are pets at home, then nothing threatens them either.
On the footrest there is a mechanism with which the ring can be turned on the sides by 90 degrees, and the tilt angle can also be changed by 10 degrees. The comfort of using a bladeless fan is enhanced by the 360-degree rotation option. Thanks to this, the zone of distribution of cool and fresh air increases. Operation is simplified by the remote control.
Bladeless fans pass about 500 liters of air per second. The air is evenly distributed when leaving. When creating this device, the developers took as an example the work of a conventional jet engine of an aircraft.
