Technology

Jet engine technology. Reduced turbulence.

Dyson fan airflow schematic

Mixed flow impeller.

Using technologies found in turbochargers and jet engines, a mixed flow impeller draws air into the machine. The eleven impeller fins are asymmetric, so each one harmonizes with the others, balancing the tone. And every one has a scalloped trailing edge, to reduce turbulence and further improve acoustics.

Airfoil-shaped ramp.

After the impeller builds air pressure, up to 10 gallons 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 cooling.

Air Multiplier™ technology airflow schematic

Inducement and entrainment.

Air Multiplier™ technology exploits the Bernoulli principle, which creates an area of low pressure. This induces air behind the fan, while surrounding air follows the airflow in a process known as entrainment – amplifying the initial airflow by as much as 15 times.

Helmholtz cavity.

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.

Less energy, less noise.

Excellent Fan

At first I was not sure I wanted to spend that much on a fan, but after turning it on, it was worth every penny. Very quiet, and powerful, and does not take up much room. Thank you Dyson.
