Energy-saving of OPT HVLS VS small high-speed fans

★Compared with small fan:

The area covered by a large open series fan with a diameter of 7.3m is approximately equal to the coverage area of 50 0.75m small fans. For example, in a  factory building with 9000 square meter, in order to achieve full coverage effect, it needs about 300 small fans, while only 6 large fans are needed to achieve the same effect . If the 6 sets OPTFAN have being used for 4 years, 8 months per year, 10 hours per day, the total operation time is about 10000 hours. The power consumption of large fans is 90000 kW · h, and the power consumption of small fans is 1080000 kW · h. The energy saving is 990000 kW · h and 92%.
