The coverage area of an EURUSII with diameter of 7.3 m (24ft) equals to that of 50 small sized 0.75 m (about 2.5ft) fan. For example, in a 9000 square meter factory, the overall coverage of the factory requires 300 small size fans at least, while only 6 industrial energy-saving fans of EURUSII could solve the problem . The operation of 10000 hours cost 90000Kw electric power for EURUSII but 1080000kw electric power for small sized fan, which means it could save  990000kw electric power(92%)!
Energy-Saving Effect
The coverage area of an EURUSII with diameter of 7300 mm (24ft) equals to that of 45 small sized 0.750 mmM(about 2.5ft) fan. For example, in a 6000 square meter factory, the overall coverage of the factory requires 150 180 small size fans at least, while only four industrial energy-saving fans of EURUSII could solve the problem. The operation of 1000 hours cost 6000Kw electric power for EURUSII but 54000kw 64800kw electric power for small sized fan, which means it could save 48000kw 58800kw electric power(90.7%)!
Comparison for the application attribute of the samll powerful fans
Applied in spring and autumn: It is awkward for commercial mall and supermarket to decide whether turn on the aircondition or not. However, after applying the super large energy saving fan, we could enjoy the natural ventilation and cooling without turning on it and quite energy-saving.
The energy consumption is great when turning on the air conditioning units, but it is totally different if used in combination with the super energy-saving fan, it can mix the air very well and reduce the working time of the air condition or turn off some directly, extremely economic.
