The manufacturing of fans has a history of over a century. Our main products include large industrial blowers, ventilators, gas blowers, coke oven blowers, multi-stage high-pressure centrifugal blowers, single-stage high-speed centrifugal blowers, etc. They are widely used in steel smelting, thermal power generation, new dry-process cement, petrochemicals, sewage treatment, waste heat recovery, gas recovery and nuclear power and other fields. Fan products are an essential part of the large-scale industrial manufacturing chain and play a crucial role in numerous industries such as chemical engineering, manufacturing, and energy. Developed countries like Europe and the United States, due to their leading technologies, have always imposed strict technological blockages on China's fan industry. High-end fans have always been dependent on imports, especially ultra-high temperature and ultra-high pressure products. Therefore, The advancement of fan manufacturing technology is directly related to the strength of a country's manufacturing industry. It is no exaggeration to say that a strong fan industry means a strong Chinese manufacturing industry.

According to the prediction of Qianzhan Industry Research Institute, in 2017, the market size of China's fan industry reached over 150 billion yuan. From the perspective of the development of the fan industry itself, the general functional fan market is already in a mature stage. As this type of fan is still a necessity in the manufacturing of the mechanical industry, there is still a certain market demand, but the development space is not large and the market competition is fierce. The market for major technical equipment fans is in a period of rapid growth. Whether it is the transformation or new construction of large-scale equipment in metallurgy, petrochemical, environmental protection and other industries, or import substitution, all provide broad development space for the market of major technical equipment fans. Multinational enterprises are competing to enter, leaving fewer and fewer opportunities for Chinese fan manufacturing enterprises. How to open the door to "Made in China"? To promote the rise of "Made in China", enterprises need to find their own keys.

In Linyi, Shandong Province, there is a fan manufacturing enterprise. It was established in 1979 in the revolutionary old area of the Yimeng Mountain region and was formerly a designated fan production unit by the Ministry of Machinery and Electronics Industry of the People's Republic of China - Shandong Linfeng Technology Co., LTD. After 37 years of innovative development, The company has successively been awarded the titles of "High-tech Enterprise of Shandong Province", "Garden Factory", "Advanced Enterprise in Management Innovation", "Model Demonstration Enterprise of 6S On-site Management", "Famous Trademark of Shandong Province", "Famous Brand of Shandong Province", "Contract-abiding and Creditworthy Enterprise", "AAA Credit Enterprise", and "2014 Shandong Province Enterprise Technological Innovation Award". Numerous awards and honorary titles such as the "2015 Shandong Provincial Science and Technology Progress Award". The company has passed the ISO9001:2000 quality system certification, product energy-saving certification and other internationally recognized certification standards at an early stage. With the goal of "becoming an innovator in the global fan industry", the company has been constantly striving forward. After years of technological research and development, it has obtained 11 technical patents. In 2014, it was listed on the National Equities Exchange and Quotations (stock name: Linfeng Co., LTD., stock code: (831132), it has laid a solid foundation for the enterprise to compete with foreign rivals and participate in the global business market competition. Currently, the products are exported to dozens of countries and regions in Europe, America, Southeast Asia, etc., making it the leading enterprise in the domestic high-temperature fan industry and gaining recognition from many foreign customers. In 2016, with the delivery of the high-end film supporting fan project in Aomori, Japan, Linfeng Co., Ltd. has firmly established its reputation as the leading enterprise in high-temperature fans. While receiving a large number of overseas orders, Linfeng people did not stand still. Recently, Linfeng Co., Ltd. announced a cooperation with Xin Changhong, a leading domestic intelligent three-box power control enterprise, to jointly develop an intelligent control system for wind turbines, once again taking the lead in the industry.

The intelligent control system for fans has always been a technology that foreign fan manufacturing enterprises are proud of. It can control the air volume changes of the fan in real time, achieving the effect of energy conservation and environmental protection. In several large state-owned fan enterprises in China, most of them cooperate with foreign enterprises and only use the intelligent control system for fans in major national key projects. All along, Fan products with intelligent control systems for fans cannot be popularized in small and medium-sized projects due to their high cost and technical difficulty. Now, Linfeng Co., Ltd. will, through its own efforts, bring the intelligent control system for fans into more manufacturing enterprises along with its products, contributing to energy conservation, emission reduction and environmental protection. Linfeng Co., LTD. It will lead the traditional fan industry to rapidly move towards the intelligent era.
