How Do Bladeless Fans Work: The Physics of Air Multipliers
Are bladeless fans without fan blades?
‘Bladeless’ fans? If there are no blades, is it even a fan? We will try to demystify how a bladeless fan works without blades in this post.
No, it is not that the blades in a bladeless fan are missing. In the case of bladeless fans, there is a small fan with blades, which remains hidden in the device’s casing. Since this is not visible to the user, it appears that the bladeless fan conjures air out of thin air.
How Does Bladeless Fan Work?
Bladeless fans have a hidden propeller in their base, which draws air into the pedestal and up into the bladeless ring. The air is then pushed through a loop and accelerated through a narrow slit, resulting in a powerful and consistent airflow. which is shaped in such a way that the expelled air pulls even more surrounding air into and through the ring.
Bladeless fans vs Traditional fans
How a bladeless fan works is different from how a traditional fan works. A traditional fan with blades pulls in the air and cuts it through, with each blade sending a slice of air to the living space at high speeds. This in turn creates a turbulent and forceful airflow.
In comparison, the bladeless fan pulls the air through a small vent in the pedestal base of the fan. The impeller creates a negative air pressure while simultaneously drawing in more air. All this air is pushed up to the ring of the fan, and expelled through a slot in the fan’s ring.
Cleaning and Maintenance of Bladeless Fan
Maintaining bladeless fans is a breeze, thanks to their blade-free design. Users can easily wipe down the smooth surface, eliminating the hassle of disassembling and cleaning individual blades. Regular cleaning ensures optimal performance and longevity.
Applications and Versatility
Bladeless fans are versatile in terms of placement, fitting seamlessly into various environments. Their sleek design allows for easy integration into living rooms, bedrooms, or even office spaces, offering a stylish yet functional cooling solution.
Bladeless fans are energy efficient since they use a BLDC motor to power the small fan inside. Bladeless fans in India are less commonly found since the bladeless fan price is on the higher side compared to traditional fans. However, if you prefer noiseless operation, power efficiency and faster cooling, a bladeless fan can prove to be a worthy investment that can also provide a sense of luxury.
