Dyson's Airblade Tap hand dryer has recently been approved in New Zealand and Australia by Hazard Analysis and Critical Control Point International (HACCP) under the non-food product certification scheme, meaning it is safe for use in the food and beverage industry.

Infrared sensors pinpoint hand positions and release water from the tap stem. Once hands are wet and drying is requested, integrated circuitry activates the latest Dyson digital motor, creating two high velocity sheets of air on the tap’s branches. This digital pulse technology accelerates from 0-90,000rpm in less than 0.7 seconds!

Using Airblade technology, the Dyson Airblade Tap hand dryer sends sheets of 430mph unheated filtered air towards hands literally scraping them dry.  Hands are dry in 12 seconds and there is no need to touch anything.

Clive Withinshaw, Director of HACCP International says, "The technology addresses a number of unacceptable risks posed by hand dryers in the past.  It's easy to clean and is a touch-free system.  It also has a fast-dry cycle.  With the inclusion of a HEPA filter, these features combine to considerably reduce the risk of microbiological contamination and thereby meet HACCP International's non-food product certification scheme criteria."

The Dyson Digital Motor V4

The Dyson Airblade Tap hand dryer is powered by the Dyson digital motor V4; a power dense brushless DC motor, utilising a bonded magnet encased in a carbon fibre sleeve.  It is one of the world’s smallest and fully integrated 1600W motors.

Hygiene 

Warm air hand dryers use 60 year old technology that relies on evaporation to dry hands.  Washroom air, which contains fecal germs and bacteria, is heated up and blown unfiltered onto people’s shoes, clothes and freshly washed hands.  The Dyson Airblade Tap hand dryer passes washroom air through a HEPA filter to remove 99.9% of bacteria before it’s blown onto hands.

Sensor Operation

Independent infrared sensors allow the user to have as much water and air as they want according to need.  An aerator mixes the water and dispenses water across hands to reduce the volume of water used and the flow rate of water is controlled by motion detection.

Materials

The Dyson Airblade Tap hand dryer is made from 304 stainless steel; an anti-corrosion steel.  Dyson engineers used specialised laser welding technology to weld tough steel accurate to 0.08mm, using temperatures as high as 1400°C.  The laser precision means that there are almost no joining lines — air, water and electrics are contained in a smooth package at the sink.

The Dyson Airblade Tap hand dryer is guaranteed to last for five years and is available in three varieties for different washroom applications; wall-mounted or counter-top with a long or short stem.
