Circulator (low noise fan / large airflow type) Delivering a large airflow with little noise, this circulator is great for daily life. Uses totally enclosed condenser motor to reduce electricity consumption, as well as ball bearings in the rotating areas to reduce vibration and noise. Features effective ventilation as well as a design based in fluid mechanics for a reduction in air being disturbed by the surface of the spinning blades, the primary source of noise in fans. With the synergy between the fan and blades, a large airflow is provided with little noise.
