. Some tower fans are quiet but weak. Others are powerful but noisy. The Dyson AM07 Cool tower fan is quiet and powerful. With no blades or grille the Dyson AM07 fan is safe easy to clean and doesn\'t cause unpleasant choppy air. It uses Air Multiplier technology to draw in surrounding air and channeling it\'s direction to create areas of low pressure resulting in a powerful stream of smooth cooling air. The Dyson AM07 has been engineered to significantly reduce turbulence throughout the machine. Airflow paths have been streamlined allowing air to pass through the machine with greater efficiency.  It\'s also designed with a Helmholtz cavity that captures and dissipates sound from the motor - making it 60% quiter than the previous generation. It\'s even been awarded a Quiet mark award for improved sound quality bu the noise abatement societyFeatures Power 56KW10 Airflow Settings9 hour timerAir Multiplier technology60% quieter than AM02 model10% less power consumed compared with AM02 modelWhite/Silver ColourRemote control includedW x H x D 190 x 1007 x 110mmWeight 2.95Kg. .
