The electric fan GreenFan2 produces a soft breeze, using little energy. It is particularly quiet and effective, even over a great distance. Due to the unique, double-blade construction it generates an outer and inner airstream to prevent unpleasant air whirls. Thanks to this special technology, a pleasant breeze, similar to nature, is generated with a range of up to ten metres. The brushless DC motor consumes thereby only a tenth of the energy compared to conventional models and with 13 dB its noise level is extremely low.
