The air circulation fan GreenFan Cirq has a brushless DC motor and produces a strong airstream at low energy consumption. The GreenFan technology, due to its unique double-blade construction, generates an outer and inner airstream to prevent the annoying air whirls. Thanks to this technology, the GreenFan Cirq produces a strong air circulation, reaching up to 15 metres, the feature which makes it clearly differ from conventional models. With this very energy-efficient device a quick and effective air circulation is produced and a pleasant balance of the temperature differences between ceiling and floor is achieved.
