What is the wind speed rating of HVLS large industrial fans?

Large-scale industrial fans are translated from foreign HVLS-FANS. HVLS itself means High-Volume, Low-Speed, that is, the high air volume, and low speed. So how much wind speed can HVLS large-scale industrial fans achieve? What level of wind power? First of all, wind force refers to the strength of the wind blowing on the object. Generally, according to the various phenomena produced by the wind blowing on the ground or water objects, according to the wind speed at a height of 10 meters in the standard meteorological observation field, the magnitude of the wind force is divided into 18 levels, the minimum is 0, and the maximum is 17. Because wind above level 12 is very rare, we generally express wind speed in meters per second. The following introduces the common 0-12 wind and the corresponding wind speed.

The normal performance of the HVLS large-scale industrial fans that are common in the market is 0-6 m/s. From the above table, it can be seen that it is a 0-4 level wind similar to natural wind, so it has a very comfortable human body feeling.
