The Science of Airflow: How Duux Use Research to Build a Better Fan

Duux Whisper fans really live up to the name, with sound levels as low as just 13dB, they are quieter than a whisper. What’s more, despite the ultra-quiet operation, we have been able to generate incredible cooling power from our fans and reduce energy consumption. While this may not seem possible, we are able to achieve this through in-depth research into airflow.

What Is Airflow?

Airflow is how air moves from one place to another, usually because of differences in pressure. Airflow is very important for fans because it affects air circulation, cooling and comfort.

Smarter Fan Design with CFD

To better understand airflow, we collaborated with Aerows Engineering who run special computerised tests, called Computational Fluid Dynamics (CFD) to test and improve performance. CFD helps engineers see how air flows through and around a fan which lets them fine-tune the design for better performance.

More Air, Less Noise

With the insights we get from CFD, we can make small but powerful changes to the fan blades and housing:

• Better Airflow: Adjusting the shape and angle of blades to help move more air with less energy.
• Less Noise: Optimising the structure of the fans helps to reduce sound, making them incredibly quiet, especially at lower speeds.

Quieter Operation with Acoustic Analysis

We also work with Sorama, a Dutch expert in sound technology, to reduce the noise level of our fans. By working with Sorama we can:

• See Sound Waves: Advanced technology is used to show us how sound waves interact with the different parts of the fan.
• Make Fans Quieter: These visualisations help us to identify noisy areas and reduce unwanted sounds.

Energy-Efficient Cooling

Duux fans are designed to use less power while keeping you cool. The improved airflow and lower noise levels mean that the fans work more effectively at lower power settings, saving energy and reducing running costs while still delivering incredible performance.

Fan Performance Triangle

When choosing a fan, most people focus on three main factors: how noisy it is, how powerful it is, and how much it costs to run. Our goal is to balance all three without sacrificing performance. Adjusting one factor can affect the others, but our expert engineers make sure that each element is fine-tuned for the best overall experience.

Below we have plotted the performance of the market-leading fan. The closer the inner green triangle is to the outside edge of the beige triangle, the better it performs.

Below is the performance of the Duux Whisper Flex, which shows increased performance on every metric. Note in particular, how our specialist research and development has led to a significantly improved airflow.

Extra Features That Deliver a Better Experience

As well as the work we put in to the performance of the fan, we also include quality of life features that help improve comfort and create a peaceful environment, especially at night:

• Night Mode: This mode runs the fan quietly and turns off bright lights from the display to help you sleep.
• Precise Speed Control: Whereas most fans only have 3 to 5 speed settings, Duux Whisper fans let you adjust airflow to your exact preference, with between 26 and 30 speed settings.
• Horizontal and Vertical Movement: Duux fans not only oscillate from side-to-side, the fan head also moves up and down, delivering powerful cooling to every corner of the room.

Why Duux Fans Stand Out

Our ongoing partnerships with top engineers help us to keep improving fan technology. Each generation of fan builds on what was great about the previous model and brings improved performance and better features. The process we use includes:

• Testing & Prototyping: Prototypes are developed which are carefully tested. This gives us insights that help us to create an improved version for re-testing and further improvements.
• Constant Upgrades: We always look for ways to improve our fans by using the latest technology to test, update and enhance products.

Our dedication to research and development has allowed us to create fans with incredible performance. The work we do with our expert partners has enabled us to innovate, reducing noise and energy consumption while increasing power. By mastering the science of airflow, we continue to lead the way in air treatment solutions.
