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.
