The fan is a necessity in every home. You will rarely find any house in India which does not have a fan. Fans make it easier for the people to bear the harsh summers. So it has become a basic necessity of life. There are a plethora of types of fans available in the market. With increasing advancement in technology, the fan manufacturing has also reached to altogether a new level. Traditionally we just knew the conventional type of fan that is the ceiling fan having 2-3 blades. The royal courts and palaces then started using other different kinds of ceiling fans. Those with 5 or 8 blades became prominent. Later, people started using fans as a means of decorating their home interiors. Fans having light lamps attached to them were used to adorn the large palatial houses. Whatever be the design and style of the fans, the basic technology remained the same. All these fans mentioned above have blades which define their working mechanism.

Later, the development of the bladeless fans took up. Have you ever seen a bladeless fan? Isn’t it difficult to imagine? Such fans do exist. You can view plenty of them on websites like,,, etc.

In this article, we will know the energy efficiency of bladeless fans. But before we move on to discuss the energy efficiency of DAM, let us know about the features of the bladeless fans.

Bladeless fans, also known as ‘Dyson Air Multiplier’ were introduced in the market in the year 2009. Holes are present on the body of the bladeless fans through which the air is taken inside. Here the air rotates the blades of the turbine present inside the body of DAM. The air is accelerated in the duct surrounding the circumference of the fan and is blown out through a hole at one of its ends.

Efficient in design

The bladeless fans are more efficient in their design. In the conventional fans, the circulating air is obstructed by the blades and therefore the energy is lost. This does not happen in the bladeless fans where the air circulates in a duct and the energy is utilized in giving the cooling effect to the people.

Energy efficiency and air flow

The biggest challenge that the scientists have overcome is to maximise the air flow, thus reducing the resistance and the air turbulence to the minimum. Bladeless fans provide higher energy efficiency and air flow as compared to that of the traditional fans. The duct used in the design and manufacturing of a bladeless fan affects its efficiency to a great extent.

Apart from being highly efficient energy saving devices, bladeless fans are also great in physical looks and offer convenience to the users. There use is comparatively safer for the kids and the pets and give you the much-needed comfort through the breeze-like oft wind produced by them.

These bladeless fans are the new invention and will help you save energy in the long –term too. Today, when everyone wishes to move closer towards a green world, bladeless fans can be a significant contributor in the Green Movement. They produce much more energy for the same amount of power consumption like that of the conventional fans with blades.
