The price of a conventional large industrial fan generally fluctuates around RMB 15,000. This only refers to a large industrial fan with conventional configuration. For some large fans with special requirements, the quotation may reach more than 20,000, or even higher. Manufacturer selection: 1. Choose a company with a large scale and its own manufacturer, not a dealer. 2. Products and core technologies. Whether the product range is complete, whether the industrial fan is safe, whether the application scenarios are comprehensive, whether it has core technology, etc. 3. After-sales service and guarantee, look at the market and feedback from customers we have served before. The industrial fans that our workshop type company bought from Chongqing Fenghua Mechanical and Electrical Company were of very good quality and after-sales service. They have been used for more than a year and the ventilation and cooling effects in summer are very good.
