Unlike traditional fans that rely on rotating blades to generate airflow, Dyson bladeless fans create a smooth and powerful stream of air without the use of visible blades.

At the core of the Dyson bladeless fan is a powerful motor located within the base of the appliance. This motor drives the operation of the fan and enables the creation of a continuous and seamless airflow. The motor draws in air through a small aperture at the base of the fan.

As the air is pulled into the fan, it undergoes a series of engineering processes to amplify and shape the airflow. The first step in this process is acceleration. The motor rapidly increases the speed of the incoming air, creating a high-velocity stream.

Once the air reaches a certain velocity, it is directed over an annular aperture, which is a ring-shaped opening located at the top of the fan. The annular aperture serves two important purposes: directing the airflow and creating a low-pressure zone.

As the high-velocity air passes over the annular aperture, it creates a low-pressure area just behind it. This low-pressure zone induces surrounding air into the air stream, a phenomenon known as inducement. By drawing additional air into the stream, the fan creates a multiplier effect, amplifying the volume of air being expelled from the fan.

The amplified air stream then emerges from the annular aperture, creating a smooth and powerful breeze. The absence of visible blades in Dyson bladeless fans not only improves safety but also eliminates the choppy and turbulent airflow produced by traditional fans.

The control and precision of the airflow direction are achieved through the design and engineering of the annular aperture. It is carefully crafted to maximize the efficiency of the airflow, ensuring a consistent breeze throughout the room.

The result is a bladeless fan that delivers a powerful and smooth stream of air, providing a comfortable cooling experience.
