In a Blade-less fan the air flows through the channel in the pedestal of the fan when the motor is turned on. After that, the air flows through the hollow tube. Then the air is shot out through 16-mm slits. This air flows smoothly, rather than turbulently as with a blade fan. The curvature of the inner wall of the fan creates an area of negative pressure – like an airplane wing – to draw more air into the flow, hence “multiplying” it. This property of the air is called inducement. Further, the air surrounding the edges of the fan also begins to flow with the direction of the breeze, or is “en-trained” to it. Dyson fan manufacturer Jameco Electronics claims that the air-multiplier technology increases the output of the air flowing through the tube by at least 15 times compared to the airflow put out by a traditional bladed fan.
Air Multiplier and its Features:
An air multiplier is and has been a multidimensional approach to fan and their overall development. By quicker means the more research if done in this arena will bring revolutionary products for this category. We see blades in fans and know how they function. As a matter of fact a blade-less fan is made of air multipliers which in turn gives a quicken effect on the air flowing through it with enhanced pressure.
The Concept of Blade-less Fan:
It gives a completely new dimension to the regular fans in general use. When we think of a bladeless fan the first thing that makes it a fan will be a air blower, in this case it’s a air multiplier fitted unto the fan. The more the innovation lighter the fan. Blades are the very basic components for a fan, while they make the air flow as a breeze in a room or any closed premise. Well it also helps keeps the ventilation good.
Working of Blade-less Fans:
The working is simple but elaborate as in the technology is called air multipliers. There the air circulation pressure on the fan mount is made to increase into a viscous shearing air known to be the fan breeze. The process is completed at high speed every time the surrounding air is drawn into the section. A bundling effect by the fan makes the air pressure to increase thereby causing the surrounding air to form a viscous air flow out of the panel.
Types of Blade-less Fans:
There are two main types of blade-less fans: those shaped like a hollow circle or oval and those shaped like a thin tower. Both offer the ability to cool the air without the worry of dangerous blades. The hollow shaped ones also are easy to clean because of few moving parts. They are also pretty energy efficient. However bladeless fans vary widely in price. They are a formulation of classic style , which is given as a luxury product. The working is similar as considered to the functions while the design differs in shape and orientation of height.
