To make fans work quietly,
manufacturers use slow-running
motors to spin the blades. This
reduces noise but also reduces
power, producing weak airflow. To make powerful fans, they
use fast motors to spin the blades.
But fast motors create more noise. Powerful and quiet is very difficult
to achieve in a conventional fan. The new AM06 desk fan has been
engineered to be quieter, and use a brushless DC motor that consumes 30% less energy than AM01
– yet generate powerful airflow.
