Key features

Detailed image of Dyson Airblade dB technology

Dry hands in just 12 seconds¹

Airblade™ technology forces sheets of air through apertures at 420mph, literally scraping water from hands, quickly and hygienically.



Scrapes away water at 420mph

The Dyson digital motor V4 uses digital pulse technology to spin at up to 92,000 rpm – up to three times faster than a conventional motor. So it can draw up to 7.4 gallons of air per second through the machine.

Key technology

The Dyson digital motor V4

The reprogrammed Dyson digital motor V4 uses digital pulse technology to draw up to 7.4 gallons of air per second through the machine, for fast hand drying.

HEPA filter

The Dyson Airblade™ hand dryer's HEPA filter captures 99.97% of bacteria-sized particles² from the washroom air. So hands are dried with cleaner air. Antimicrobial coating and touch-free operation helps to prevent the spread of bacteria. So Dyson Airblade™ hand dryers meet every part of NSF Protocol 335, which defines the criteria for hygienic hand dryers.
