Industrial fan technology is designed for energy saving and consumption reducing, improving the working environment of comfort and the development of a range of products. As we all know, cool and comfortable effect is not achieved only by refrigeration cooling fan blowing area also depends on the diameter of the fan, and the fan speed has nothing, and industrial fan low speed for large diameter this is a combination of these characteristics. Rock fans-industrial engineer for electrical equipment after years of painstaking research and explorations, integrate advanced aviation technologies and develop a performance highlighting the propeller blades, just slowly rotating in the air creates a continuous, quiet breeze flowing. Unique high efficiency Airfoil blades slowly rotating mass flow down, which builds into a near-perfect propeller exhaust. Industrial big fan produced of wind speed about for 2-3 m/s, completely is according to air over human skin produced best cool feel of air calculation out of, too strong of air will let people physical and mental was hot, has a was wind straight blow of feel, high of wind speed also will makes people dizziness, only through surface of volatile and Breeze speed of organic combined, to landscaping human of cool feel.

As large industrial buildings the fan diameter of the fan running and the formation of a large number of air pushed down, meet ground creates horizontal air flow, similar to the level ground jets. Air diffusion size and the fan diameter and fan blade rotation speed, if the fan run continuously, flow outward in a lot goes on until it encounters the side walls or obstacles rise, so as to continuously make up air circulation, which is industrial fans are so efficient characteristics. No matter what quantity of small high speed ceiling fans will not have such a large multi-faceted breeze of air, usually 2.4 meters in diameter fan can have a depth of approximately 1 m on the ground level air laminar flow, and 7.2 m diameter air flow fan can have a depth of 2.8 on the ground levels.
