Shedd Aquarium case study

Dyson Airblade dB hand dryers in Shedd Aquarium

Hands going into Dyson Airblade dB hand dryer

The business

Built on what used to be a landfill site, the John G. Shedd Aquarium first opened its doors in May 1930. Today, it is one of the world's largest indoor aquariums, home to more than 32,000 aquatic creatures from around the globe.

Conventional hand dryers

The problem

The aquarium launched an ambitious sustainability plan which included installing hand dryers to reduce waste from paper towels. Soon enough, they started experiencing noise issues with the hand dryers which were disturbing guests during large events – they even had to turn them off to reduce noise.

Shedd Aquarium solution

The solution

Robert Wengel, Vice President of Facilities, was excited to learn about Dyson's sound improvements with the Dyson Airblade dB hand dryer. Dyson engineers significantly reduced air rush noise and incorporated Helmholtz silencers to absorb the unpleasant frequencies produced by the motor – making it quieter.¹


  • Quick and easy maintenance

    Other hand dryers can take up to 24 seconds to dry hands. The Dyson Airblade dB hand dryer uses two high-velocity sheets of air to scrape water from hands – drying hands in 12 seconds.²

  • Acoustically re-engineered

    The Dyson Airblade dB hand dryer has been acoustically re-engineered to be quieter than the original Dyson Airblade™ hand dryer.

  • Lower environmental impact

    Up to 71% less expensive to run than other hand dryers.³ Up to 98% less than paper towels,³ with up to 78% less CO₂.⁴ Creating a better environment in your restrooms and in the world outside.
