What are the Advantages
In an article in Infect magazine D.R. Patrick says “The first line of defense against spreading bacteria is washing and drying hands properly. Washing alone isn’t enough. Damp hands can spread up to 1,000 times more bacteria than dry hands." A paper presented at the 17th European Congress of Clinical Microbiology and Infectious Diseases, Munich, Germany in 2007 by the University of Bradford and Dyson showing that for a set drying time of 10 seconds, the Airblade led to significantly less bacterial transfer than with the other driers.
There are economic advantages as well. The Airblade uses up to 80% less energy than a hot air dryer because it works more quickly and doesn’t have to heat the air. Compared to paper towels the Airblade can dry 22 hands for the same cost as one paper towel that’s a 94% savings.
The Airblade is also HEPA certified to clean hands with 99.9% bacteria free air. This means that air that comes out of the Airblade will not add bacteria to your freshly washed hands.

How Does it Work
The Dyson hand dryer works by sucking the dirty bathroom air in and running it through the HEPA filtration system. The, now clean, air is forced through two small air accelerating apertures that create 400 mph sheets of air that scrape the water from the hands. The secret to this device is the digital motor that Dyson developed. It works by pulsing electric currents into a magnetic reaction chamber to drive the motor to upwards of 81,000 rpm. The suction created by this motor drives the airflow.

What Kind of Saving Does This Unit Offer
There is a cost calculator on the Dyson website that will allow you to estimate the annual savings you could expect to see based on your current method of hand drying, the number of drying units and the number of uses per day. On the low end, a business with one warm air hand dryer that is used 100 times a day will have an estimated savings of $73.18 a year. A medium sized business with 200 employees and four warm air units could expect savings of $292.70. A large corporation with 70,000 employees using paper towels would stand to save up to $499,064.63 a year. This unit simply makes sense for businesses of all sizes. It will pay for itself in a matter of years and is covered by a five year parts replacement and one year labor warranty.
The unit is available in both a silver die cast aluminum and a Polycarbonate-ABS casing with homogenous anti-microbial additive finish (Grey or White). Both of these have been real world tested to withstand any and all situations that are likely to occur in a business setting including vandalism. For a base price of $1,199.00 this is a great long term investment.
