Jet engine technology. Reduced turbulence.
After the impeller builds air pressure, up to 38 litres of air per second is forced up into the eccentrically aligned loop. It's then accelerated over an airfoil-shaped ramp, which harnesses the Coanda effect to manipulate the powerful flow of air. Airflow clings to the ramp, which is angled at precisely 16° – channelling its direction for optimum personal fan cooling.
Inducement and entrainment.
Air Multiplier™ technology exploits the Bernoulli principle, which creates an area of low pressure. This induces air behind the fan, whilst surrounding air follows the airflow in a process known as entrainment – multiplying the initial airflow by as much as 15 times.
The acoustically engineered motor bucket houses a Helmholtz cavity. When sound waves enter the cavity, the pressure fluctuation within the chamber reflects them back. The waves are bounced within the cavity, dissipating sounds in the range of 1,000 Hertz – similar to the tone produced by a mosquito’s beating wing. This improves the tonal quality of the machine.
Brushless DC motor.
The newly calibrated brushless motor provides variable power, rather than the limited settings on conventional motors. It generates powerful airflow, whilst using less energy.
Airflow is separated into controlled paths and streamlined, so that air passes through the machine quietly and with greater efficiency. This means the motor can be calibrated to run more slowly while generating powerful airflow, further reducing overall noise.
