The business
The O2 is an entertainment district in Greenwich, London. It's home to the world's busiest arena, with over 2 million visitors every year.

The problem
The O2 was using 2.3kW warm air hand dryers. "They were simply too slow and used too much energy for a venue of our size and footfall," explains Lee.
The solution
-
Faster dry times
430mph sheets of air scrape water from hands, drying them hygienically in just 10 seconds. -
Costs less to run
Most hand dryers are slow, so they're energy-hungry. Dyson Airblade dB hand dryers cost up to 72% less to run than other hand dryers.*
-
Now 50% quieter
The Dyson Airblade dB hand dryer is 50% quieter than the original Dyson Airblade™ hand dryer, but dries hands just as quickly.
