HVLS means High Air Volume, Low Rotating Speed. The HVLS Air Fan is the new solution of Energy Saving to solve the ventilation & cooling problem of large space. The HVLS efficient industrial fan system completely solved the ventilation & cooling problem of large space. It can be separately used in large public space, such as large workshop, agriculture, warehouse, supermarket, gymnasium etc. It can also be used with air condition system to reduce the energy consumption of the air condition. This method not only achieves the purpose of energy saving and comfortable, but also to reduce the production operation cost. Technology principle The traditional industrial fan runs at high speed to accelerate the ventilation and liquid evaporation from skin so as to make the cooling effect. But in the strong wind for long time, we usually feel discomfort of hot and dry. And the coverage of the traditional industrial fan is very small. In contrast, the HVLS super large industrial fan runs at low speed to slowly move a lot of air in large area through the super large fan blade so as to produce large and gentle natural breeze and continuously blow away the moisture from skin. So it can effectively accelerate the liquid evaporation from the body surface and thus bring the cool feeling. In the covered large space, people can feel 3 degree celsius to 5 degree celsius temperature reduction through the evaporation effect of the HVLS super large industrial fan. So it can effectively solve the cooling problem of large spaces.
