Industrial fan technology is designed for energy saving, improve the comfort of the work environment and the development of a series of products. As we all know, the cool and comfortable effect is not only achieved by cooling the cooling; the fan blowing area also depends on the fan diameter, and the fan speed is not the slightest relationship, and low speed large diameter industrial fan which is combined with these features. After years of painstaking research and exploration, the integration of foreign advanced aviation technology and developed a prominent performance of the propeller blades, just slow rotation in the air to form a continuous, quiet breeze flowing. Unique and efficient wing-type blades slowly rotate to produce a large amount of airflow to push down, thus building a near-perfect propeller exhaust. "Industrial fan" wind speed is about 2-3 m / s, is entirely based on air flow over the human skin to produce the best cool air volume calculated, too strong air will make people feel hot and humid, there is a wind Straight blown feeling, too high wind speed will make people dizzy, only through the surface of the volatilization and the combination of micro-wind speed, in order to beautify the body's cool feeling.
