The Dyson Airblade(TM) is the fastest hand dryer - and it's hygienic, too, cleaning the air before blowing it onto hands. And because it uses up to 80% less energy than warm air hand dryers, it costs less to run and can help lower a business's carbon footprint. AB04 is designed for regular washrooms. It has the same patented technology as AB02 but it's made from PC-ABS - a lightweight yet durable compound. Its manufacturing process is over 50% less carbon intensive than AB02.
