The first time I saw this product was when I visited the renben bearing workshop. There was a gust of wind in the workshop. When I looked up, I saw a super large fan. It was the first time I saw this. I was not only surprised by his big Mac, but also surprised by the wind when I took a few steps. At that time, I thought it was very good. Later, my company built a new factory. I just like the company recommended this product. After understanding, many of my colleagues installed Weiyu industrial ceiling fans with good quality. After contacting Zhejiang Weiyu ventilation mechanical and Electrical Co., Ltd., the other party received us very warmly. We visited the factory, explained it, and went to our new factory area to survey and plan on the spot. And finally reached cooperation. Now after 5 years of use, there is no problem in the quality. Every year, we come to our factory to do maintenance. The leader is very satisfied!
