Like all Dyson fans, AM07 has patented Air Multiplier technology for powerful airflow projection. Air is accelerated through an annular aperture, drawing in surrounding air to project a powerful, cooling flow of high-velocity air. And with no blades, the airflow is smooth – not choppy. Dyson engineers developed AM07 to be quieter and more energy efficient than its predecessor, with no compromise in performance. AM07 is 60% quieter than its predecessor AM02. Streamlined air channels reduce airflow turbulence so that air passes through the machine more quietly and with greater efficiency. It also has an acoustically engineered motor bucket to reduce vibration and therefore noise. Energy efficiency has also been improved. With smoother airflow through the machine, the DC motor doesn’t need to work so hard so less energy is required to channel the air for the same performance. Energy wastage has been reduced with the addition of a sleep-timer – enabling you to set exactly when you want the Dyson Cool to be working. The fan can be programmed to turn off after preset intervals ranging from 15 minutes to 9 hours. AM07 comes with a remote control providing 10 precise airflow settings – as well as one touch oscillation control for smoother oscillation. For extra convenience, the remote is curved and magnetized to store neatly on the machine. With no blades and no awkward safety grilles, all Dyson fans are very easy to clean. And they all come with a free 2 year guarantee – parts and labor.
