Fan fan manufacturers have? Specifications many? What price? Weathervane brand is it?

Edit: Standard Electrical Co., Ltd. Shenzhen wind turbine experts more price and specifications, please visit our Ali official website: http: //fbemf2014.1688.com/ fan fan manufacturers have? Specifications many? What price? Weathervane brand is it? Over the past decade, rotating axial fan (hereinafter referred to spin) in the promotion and application of strong momentum of domestic coal. If we say that the 1980s and 1990s, 2K60,1K58,2K58,2K56, TLT of GAF and other non-rotating alternative 2BY, 70B2 is a new stage of mine main fan technology development; so, today the promotion of spin How to apply this evaluation, it was difficult to answer this question. Because, said non-rotating yet from the historical stage, it is impossible to exit the stage of history, there are exuberant vitality; although these sales in decline, but the non-rotating still in use. Rotating (including the main fan and the local fan) from application technology has never stopped arguing. It can be said, to promote the use of spin is in question come in technology today. I believe that through decades of promotion and application of rotating the technical debate and questioning to make periodic summary, no matter where considerations are necessary and useful. 1 Starting from its packaging products to the market, the product of scientific enterprise, seeking truth from facts promotional packaging is necessary. However, manufacturers of rotary writes in the catalog: Compared with non-rotating, rotating the highest efficiency up to 85%; compared with non-rotating, rotating to achieve a single operation; rotating impeller motor directly connected, simple structure, easy installation and maintenance; rotating outdoor installation can be used without the engine room, save a lot of infrastructure costs. In particular, said: rotating "fan caused a revolution in manufacturing." Thus, the focus of the above promotional packaging, become the focus of debate and questioning of industry technology. Now, in conjunction with the promotion of the application of a decade, one by one comb, review.
