In early May 2026, a research team from the Economic Daily Jiangxi Reporter Station, accompanied by leaders of Xunwu County and officials from the Industrial Park, launched a special investigation on “the development of Xunwu's air compressor industry”. The team visited key enterprises along the air compressor industry chain to witness the this city’ transformation from an “industrial blank” to an “industrial hub”. Then they paid a special visit to Jiangxi Sange Filter Manufacturing Co., Ltd. to gain insight into the company's growth and industrial collaboration.At the production workshops and storage areas of Sange Filter, the research team inspected the premises while inquiring and communicating in depth with the enterprise management.General Manager Han Shengjun briefed the delegation on the company’s production and operations. From the high-speed intelligent production lines to the neatly stacked products ready for nationwide distribution, the research team gained a direct impression of the company’s production rhythm and management standards.Outside the workshop, the research team also observed on-site logistics and loading operations, learned about product transportation and market coverage, and spoke highly of the enterprise’s efficient operation model.
(II) Product Exhibition & Technical Exchange: Forging Ahead in the Niche Market to Consolidate Industrial Foundations
The research team then visited the company’s product exhibition area and inspected its full range of special filters for air compressors at close range. Nearly 1,000 models were neatly displayed, covering large industrial air filters, precision oil filters and air oil separators, fully meeting all supporting needs of air compressor equipment.Company leaders elaborated on the R&D history and technical advantages of the products: Sange Filter owns more than 10 patented technologies, with products compatible with mainstream air compressor models on the market. The products satisfy requirements for filtration precision and service life under various working conditions. Some core products have reached advanced industrial levels and achieved domestic substitution of key components.The research team focused on the company’s achievements in key technological breakthroughs and product adaptation upgrades. The company adheres to the philosophy of “building an enterprise through technology”, and has established long-term industry-university-research cooperation with South China University of Technology and built a professional R&D team.Targeting the industry’s demand for high filtration efficiency, high stability and long service life, the company has continuously optimized product structure and production processes, and launched special filter elements for new air compressors. It now offers more than 3,000 mature products and customized solutions, providing one-stop supporting services for air compressor manufacturers.
(III) Industrial Collaboration: From Single-Point Breakthrough to Cluster Empowerment
During the visit, the research team spoke highly of the cluster development model of Xunwu’s air compressor industry. In recent years, relying on its industrial foundation, Xunwu County has promoted the air compressor industry with a "chain-oriented mindset". Starting from the first introduced enterprise, the county has gradually built a complete industrial chain covering complete machine manufacturing, core components, after-treatment equipment and supporting services.The annual output of air compressors in Xunwu has exceeded 200,000 sets, accounting for one-tenth of the national total, making it the production base with the highest concentration and most complete supporting facilities for the air compressor industry in Jiangxi Province.
As a key supporting enterprise in the industrial chain, Jiangxi Sange Filter is both a beneficiary and a promoter of the coordinated development of the industrial cluster. The person in charge of the company stated that since settling in Xunwu, the enterprise has achieved rapid development thanks to the sound supporting policies and industrial ecosystem of the park.At the same time, it provides nearby supporting services for local air compressor complete machine enterprises, effectively reducing their procurement and logistics costs, shortening delivery cycles, and forming a sound cycle of coordinated development between "complete machine enterprises + supporting enterprises".At present, Sange Filter’s products not only supply local complete machine enterprises, but also are sold to many provinces and cities across China, with some products exported overseas, becoming a "supporting business card" of Xunwu’s air compressor industry for external display.
The research team pointed out that the rapid rise of Xunwu’s air compressor industry is inseparable from the joint efforts of upstream and downstream enterprises, especially supporting enterprises like Sange Filter that deepen niche segments and focus on technological innovation.
The company’s continuous investment in core components has not only won itself a market share, but also laid a solid foundation for the high-quality development of the entire industrial cluster, and continuously enhanced the market competitiveness of "Xunwu-made" air compressors.
(IV) Future Outlook: Sticking to High-Quality Development to Write a New Chapter for the Industry
This special research is a comprehensive review of the achievements in cluster development of Xunwu’s air compressor industry, and also an affirmation of Sange Filter’s dedication to the niche sector and empowerment of industrial upgrading.The research team noted that Xunwu’s air compressor industry has grown from zero foundation to a 10-billion-yuan industrial cluster, blazing a distinctive path for industrial breakthrough in less-developed regions. The growth of supporting enterprises such as Sange Filter is a vivid microcosm of this journey.
Going forward, Jiangxi Sange Filter Manufacturing Co., Ltd. will continue to root itself in Xunwu’s air compressor industrial ecosystem, strengthen technological innovation and production capacity upgrading, and increase investment in new materials, intelligent manufacturing and product R&D, so as to continuously improve product quality and market competitiveness.Meanwhile, the company will further deepen cooperation with upstream and downstream partners, actively participate in industrial standard-setting and technical exchanges, and join hands with complete machine manufacturers to tackle key technical problems.Together, they will boost the high-end, intelligent and green development of Xunwu’s air compressor industry, inject stronger momentum into its high-quality growth, elevate the influence of the “Air Compressor Made in Xunwu” brand, and write a new chapter in the high-quality development of industry.
