FULL LAUNCH VIDEO: Dyson launches its fastest, most efficient hand dryer yet: Airblade 9kJ


Billed as the fastest, most energy efficient HEPA-filtered hand dryer available, the Dyson Airblade 9kJ has a "completely unique design and cutting-edge technology" and is its quietest model yet.

Dyson. It's a marvellous company that makes excellent technologies with such dedication, passion, attention to detail and demolishing of pain points that other companies think is too hard, haven't even realised could be solved or have given up on, that I am happy to state that if Dyson gets into smartphones, Apple will finally have some real competition!

It's exacting standards make the recent Choice comparison between a cheap K-Mart fan vs the much more expensive but also much more capable Dyson hold and cold HEPA-filtering fan look like comparison between a basic lawnmoner to a vastly superior ride-on model, given Dyson's meticulous approach to HEPA filtration, app-controllability, remote control and more (depending on the model).

It delivers a compelling headline, effectively based on price and the ability of a cheap fan to blow air alone, and certainly not on the full palette of features and benefits Dysons offer at different. I mean, take any cheap fan and heater combo and compare it to Dyson on price and basic functionality and the cheap model wins, but on the full picture you're comparing a single tree to a forest and hoping they are the same.

So too is this the case with Dyson's entire range, where cheaper competing models exist, but Dyson sets the standard. An example concerns Dyson's hand dryers which combine HEPA-filtration, so water is effectively, with gentle forcefulness, "scraped" off your hands by a very customised jet of air.

Traditional hand dryers will try evaporative drying, blowing the dirty air of a washroom onto your hands and heating them, while those Dyson Airblade wannabe clones that collect water within their innards always blast your face and nose with the unmistakable and decidedly unpleasant scent of stale water - and dirty air, too.

This is where Dyson's Airblade units stand apart, allowing you to dry your hands quickly and hygienically, with the new Airblade 9kJ adding the benefit of very low energy usage and the quietest operation in a Dyson Airblade yet, thus offering the company's best ever alternative to single-use paper towels - with demonstrable cost savings there, too, as can be seen in the full launch video (embedded further below).

Jake Dyson, Chief Engineer, said: "At Dyson we believe hand drying should be fast, hygienic and responsible in its energy use. We solved many of these problems when we disrupted the industry with the launch of the first Dyson Airblade in 2006.

“We continue to pioneer with the Dyson Airblade 9kJ – our latest hand drying technology. From the acoustics to its design, everything has been rethought to deliver the best performance without any compromise on user experience or hygiene.”

As befits Dyson's meticulous approach, we learn that its Dyson Airblade 9kJ hand dryer machine has been over three years in development, with more than 700 prototypes made.

We're told "the result is the quietest Dyson Airblade hand dryer yet, with fast hand drying in 10 seconds".

The company proudly boasts its "motor and airflow technology allow the new Dyson Airblade 9kJ hand dryer to use up to 87% less energy than warm air dryers in Eco mode, while producing up to 85% less carbon dioxide emissions per dry than paper towels".

Founder and CEO of Dyson, James Dyson explained: "It is the instinct of engineers to want to improve things, make them more efficient and to use fewer resources in the process. It is wired into our DNA and it is this urge which drives progress and advancement – even in the washroom.

“In 1907, paper towels were first introduced and the electric hand dryer made its first appearance in 1948 – but both have their failings. The journey to find a better way is fascinating. In 2006 the invention of Dyson Airblade technology meant that, for the first time, water was scraped off hands using high velocity unheated air, thus reducing the energy consumption,” he added.

Here is the full launch video, the article continues thereafter, please read on!

As always with Dyson, the company said that "success is in the detail and the intelligent combination of hardware and software. The Dyson Airblade 9kJ hand dryer’s robust design and stainless steel body is built to last and rigorously tested to withstand real-life washroom conditions".

It also employs pioneering Dyson technology including:

A Curved Blade design

"Powered by the Dyson digital motor V4, which spins at up to 75,000rpm, sheets of air flow up to 624m/h5 through two 0.45mm curved apertures that follow the contours of your hands, removing water in less time. Our powerful Dyson digital motor V4 shifts 23 litres of air per second5, allowing the Dyson Airblade 9kJ hand dryer to dry your hands fast, in 10 seconds.

"The Dyson Airblade 9kJ hand dryer uses 9.1 kilojoules of energy per dry, meaning it costs just $19 a year to run in Eco mode".

Touch-free operation

"The machine uses ‘Time of flight’ sensors that accurately detect hands to activate air."

A hygienic HEPA filtration

"With a fleece-lined glass fibre HEPA filter, which captures 99.95% of particles, including bacteria and viruses, from the washroom air, the machine uses clean air to dry hands."

Acoustic engineering

"Our quietest Dyson Airblade hand dryer yet, the Dyson Airblade 9kJ hand dryer features silencers made from open-cell foam and perforated discs, reducing noise as airflow passes through the motor.

"To achieve the reduction in noise, Dyson re-designed the airflow paths through the machine, making them more direct and therefore reducing sound output.

"The motor housing of the Dyson digital motor V4 regulates airflow paths through the motor, reducing noisy turbulence. The motor is mounted on silicon rubber to further reduce noise, and the specially designed open-cell foam silencers absorb vibrations from air entering and exiting the motor.

"The Dyson Airblade 9kJ hand dryer costs AUD $1,590 and is designed to suit any commercial or public washroom, from offices, shopping malls and restaurants, to public spaces, amusement parks, schools, hospitals and hotels".

Additional notes from Dyson:

  • The Dyson Airblade 9kJ hand dryer has two power modes:
  • Max mode is designed for busy washrooms, for example in airports or stadiums where footfall is high and hands need to be dried quickly. Max mode uses 900W, drying hands efficiently in 10 seconds. Carbon emissions in max mode are 3.0g per dry.
  • Eco mode may be preferable for washrooms with comparatively lower footfall, for example offices or restaurants. Eco mod uses 650W and the carbon emission are 2.5g CO2 per dry. This mode dries hands in 12 seconds.
  • Conventional warm air dryers use16.8g of CO2 per dry, while paper towels use 17.1g of CO2 per dry.
  • Dyson has been developing a series of its own Dyson digital motor since 1999. Over the years, Dyson has invested more than £350 million in the engineering, development and manufacturing of Dyson digital motors. So far, we have manufactured more than 75 million motors.
