HEPA-filtered air is channelled up the machine by the motor, forcing sheets of filtered air through precision apertures at high pressure. Water is scraped from the hands at 420mph.
The reprogrammed Dyson digital motor V4 uses digital pulse technology to draw up to 5.3 gallons of air per second through the machine, for fast hand drying.
Dyson Airblade™ hand dryers HEPA filters captures 99.97% of particles, including bacteria and viruses, before it's blown onto hands. So hands are dried with cleaner air, not dirty air.
Capacitive sensors activate air to dry hands. No dirty buttons to press.
The Dyson digital motor V4 was seven years in the making - it's one of the world's smallest fully-integrated 1400W motors. It's the only hand dryer motor powerful enough to draw in 9.25 gallons of air per second through a HEPA filter, and then dry hands in 12 seconds.**
This long-life, energy-efficient motor is digitally-switched at 6,100 times per second, making the high compression fan spin 92,000 times a minute. There are only three moving parts, so there are no slip rings or carbon brushes to wear down.
Testing based on NSF Protocol P335 shows that most other hand dryers are much slower than their manufacturers claim. Many people give up when using a slow hand dryer. But damp hands can spread up to 1,000 times more bacteria than dry hands.
Testing based on NSF P335 proves that Dyson Airblade hand dryers are the fastest. The Dyson Airblade dB hand dryer dries hands hygienically in 12 seconds. Airblade technology combined with the Dyson digital motor V4 creates high speed sheets of air that scrape water from both sides of the hands simultaneously. It's the fastest way.
Small surface area - smooth single piece fascia with CNC-machined airslots.
Sealed casing infused with antimicrobial additives to protect the product.
Dyson Airblade hand dryers produce up to 79% less CO2 than some other hand dryers and up to 76% less than recycled paper towels.
Most other hand drying methods are expensive to run. Paper towels need restocking and disposal. Most other hand dryers are slow, and many use a heating element, so they're energy-hungry.
The Dyson Airblade V hand dryer costs up to 69% less to run than other hand dryers per year, and up to 97% less than paper towels.
Most other hand dryers are unhygienic. They don't filter bacteria from the restroom air. They suck in dirty air then blow it back onto hands. The Dyson Airblade V hand dryer uses two HEPA filters to remove 99.97% of bacteria at 0.3 microns from the air used to dry hands. So hands are dried using cleaner air, not dirty air.
Only Dyson Airblade hand dryers are certified hygienic by independent public health specialists, NSF international. No other hand dryers meet every part of the NSF Protocol P335. As well as having a fast dry time and HEPA filters, the Dyson Airblade V hand dryer also has touch-free operation and an antimicrobial additive.
Most hand dryers have one narrow column of air that can chase water around hands, missing areas and leaving wet patches. The Dyson Airblade V hand dryer uses two sheets of air that span the width of each hand to scrape off water like a windshield wiper.
