In 2023, two patents were independently developed and obtained. One is a low-noise axial flow fan (Patent No.: ZL2023 2 1243112.0), and the other is a mold for the consistency of axial flow local ventilation fan impeller blade angles (Patent No.: ZL2023 2 2386454.4). In terms of service, the company has always adhered to providing the optimal overall ventilation solution based on the needs of the user's environment, providing customers with comprehensive pre-sale, in-sale, and After-sale Service, winning the trust and support of customers.

In 2020, in order to solve the problem of ventilation in plateau tunnels, we independently researched and developed the patented product "Ventilation System Intelligent Control System" (Patent No.: ZL202022969888.3). In recent years, CIFEKOH Fan Co., Ltd. has kept pace with the times and continuously innovated and developed. In product research and development, we focus on the application of environmentally friendly and energy-saving technologies, and have developed a series of high-efficiency and energy-saving ventilation equipment to meet the market demand for green and environmentally friendly products.

In 2019, to achieve automatic control of wind turbine operation and meet construction environment needs, the company developed the patented products “A wind turbine automatic control system” (Patent No.: ZL 201921396255.9) and “A low-noise axial flow fan” (Patent No.: ZL 201921155692.1).

In 2010, CIFEKOH Fan Co., Ltd. entered a period of rapid development. The company actively responded to national policies and seized the opportunities presented by the development of strategic emerging industries. It successfully applied for electricity market-based transactions for strategic emerging industries, enjoying preferential electricity prices and significantly reducing electricity costs. This provided strong support for the company to further expand its production scale and invest in research and development. During this period, the company continuously increased its R&D investment, obtaining multiple technological patents and achieving technological breakthroughs in the fields of tunnel axial flow fans and mining axial flow fans. Product performance reached the advanced domestic level. At the same time, the company passed CE EU certification, ISO9001 certification, ISO45001 certification, ISO14001 certification, and CCC national mandatory product certification. Product quality and management systems have received international recognition, laying a solid foundation for expanding the international market. In terms of market expansion, CIFEKOH Fan Co., Ltd. has not only become a long-term supplier of fans for major domestic projects such as China Railway Construction Corporation, China Railway Engineering Corporation, China Water Resources and Hydropower Engineering Bureau, Shanghai Tunnel Engineering Co., Ltd., Shanghai Construction Group, and China Coal Group, but has also actively explored international markets, exporting to more than 20 countries for consecutive years, including Singapore, Australia, Canada, Malaysia, Vietnam, the Philippines, and Indonesia. Products have received consistent praise from users in the international market.

In 2010, we jointly developed the patented product "Automatic Operation Control Device for Tunnel Ventilation" (Patent No.: ZL 2010 2 0517123.X) with China Railway Tunnel Group Co., Ltd. With the increasing national infrastructure construction efforts, the company independently developed the patented product "Energy-saving axial flow fan for the construction of long and large tunnels" (Patent No.: ZL200920104028.4)

In 2009, with the increasing national investment in infrastructure construction, the company independently developed the patented product "Energy-saving axial flow fan for long tunnels" (Patent No.: ZL200920104028.4). In the same year, to solve the ventilation problem of the Qinghai-Tibet Railway plateau tunnel, our company signed a scientific research project contract with the Luoyang Institute of Science and Technology of China Railway Tunnel Group Co., Ltd. The project name is: "Research on key technical issues of TBM construction in extra-long tunnels on the western line". We jointly developed a new type of plateau ventilation fan, which obtained a national patent (Patent No.: ZL 2009 20254404.8) and won the Henan Provincial Science and Technology Progress Award. It has been applied in major projects such as the Sichuan-Tibet Railway, and has received good user reputation.

In 2003, it was awarded the title of "Civilized and Honest Unit" by the Houma Municipal People's Government. In the same year, it was awarded the title of "Top Ten Chinese Patent Enterprises" at the China International Patent and Brand Expo.

In 2002, the "High-speed Multi-speed Tunnel Construction Special Axial Flow Fan" won the Gold Award at the 9th China Patent Technology Expo and the Special Gold Award at the 10th China Patent Technology Expo. In the same year, it was recognized by the Environmental Protection Professional Committee of the China Technical Supervision Information Association as one of the first batch of "Key Protected Units for China Environmental Protection Quality and Credit" and "Key Brands for China Environmental Protection Product Quality and Credit".

In 2001, the SDF series tunnel construction and SSF series tunnel operation ventilators, DKZ, and KZ series axial flow ventilators were recommended as "China Science and Technology Fine Products" by the National Council of Science and Technology Entrepreneurs of the China Association for Science and Technology Research.

In 2000, with market expansion and diversification of customer needs, the company continuously expanded its Business Scope. The company added the production and sales of wind turbine control devices, ducts and accessories, gradually building a relatively complete ventilation equipment product line to meet the ventilation needs of more industries. During this period, the company continued to invest in technological research and development and product quality, improving its production capacity and technical level by introducing advanced production equipment and technical personnel. In the same year, it was awarded the title of "Honoring Contracts and Keeping Promises" unit by the Houma Municipal People's Government.

In 1999, it won the "Excellent Product Quality Inspection in 1999" title from the Shanxi Provincial Technical Supervision Bureau.

A patented product, "Variable-speed multi-speed tunnel construction axial flow fan" (Patent No.: ZL 002 58455.7), developed in 1998 to address the high energy consumption of old-style fans.

On August 4, 1997, Shanxi Houma Xinfengkang Fan Co., Ltd. was officially established at No. 589, Xingfu Street, Houma City, marking the beginning of its journey in the field of fan manufacturing. In its initial stages, the company mainly focused on fan production and manufacturing. By strictly controlling product quality and keenly observing market demands, it gradually established a firm foothold in the local market.

In August 1997, it applied to become a network factory of the Coal Science and Technology Group's fan development and production joint body. A joint office for fan development and production was established together with the Engineering Design Research Institute of the Coal Science and Technology Research Institute.

In December of the same year, the research and development application for a ground-use, extractable explosion-proof axial flow fan was completed. This product has been promoted for use in the coal industry, achieving satisfactory results in social and economic benefits and safety production.
