As the red silk fell, applause and cheers interwove at the scene, marking that the Jilin factory of Shenzhen Zhongjian South has officially entered a new stage of development. After the ribbon-cutting ceremony, several leaders guided the customer representatives to visit the new factory area. During the explanation, it was learned that Zhongjian South Jilin Factory was established in 2019, specializing in the research and development and production of air filtration equipment. It has multi-regional production capabilities, as well as a "full-process, scenario-based, and traceable" production quality inspection system and a biosafety control system covering the entire chain. Currently, it has corresponding personnel allocation and facilities such as warehousing and rest. The customer highly praised the production environment and overall control system of the factory. Some partners expressed on the spot that they would deepen cooperation and jointly explore new opportunities in the field. At noon, at the thank-you luncheon table, company leaders had a free and open discussion with clients about the prospects of cooperation and shared the joy with the family of China State Construction. This luncheon is not only a tribute to past cooperation and the hard work of the employees, but also marks a new starting point for in-depth cooperation between the two sides. With the relocation and commissioning of the new factory, Jilin Zhongjian South continues to take root in the fertile soil of Songyuan, delving deeply into and promoting technological breakthroughs in the field of air purification. Meanwhile, the company will deepen its cooperation with universities and research institutions, build an integrated platform of industry, academia and research, and contribute to the green development of the industry.

On August 7, 2025, the 2025 International DIC EXPO Exhibition grandly opened at the Shanghai New International Expo Center. Shenzhen Zhongjian South (known as ZJNF) showcased its FFU fan filter unit and multi-form chemical filter collaborative solution at the exhibition, highlighting its professional accumulation and innovative vitality in the field of air purification. At this exhibition, ZJNF has provided solutions to the industry pain point that particulate and gaseous molecular pollutants (AMC), such as acidic gases and organic volatile substances, may cause chip defects and uneven display during the production process of display panels, directly affecting product yield. At this exhibition, ZJNF highlighted the FFU fan filter unit and multi-form chemical filter collaborative solution. Through scenario-based customization technology, it dynamically adjusts the filter material formula, extends the equipment maintenance cycle and reduces production capacity loss, providing full-process air purification support for display manufacturing. 

In June 2025, the domestic intelligent livestock farming sector witnessed two major industry events. Shenzhen Zhongjian South (ZJNF), a leader in air pollution control and treatment technology, made appearances at both the ‌4th Intelligent Swine Industry Forum in Nanyang, Henan‌ and the ‌9th Nanjing Agricultural University (NAU) Swine Industry Conference in Wuxi‌. Showcasing cutting-edge technological solutions and outstanding product strength, ZJNF was honored with the "‌Excellent Equipment for Intelligent Pig Farming Award‌" and the "‌2025 Golden Classic Brand Award‌" at these dual exhibitions, demonstrating its prominent position in the livestock industry through innovative achievements. · ‌June 25-27, Nanyang, Henan:‌ Held at the headquarters of Muyuan Group, the 4th Intelligent Swine Industry Forum gathered top industry experts and enterprises. ZJNF showcased its flagship products, attracting domestic and international clients for in-depth exchanges and reaching cooperation intentions. · ‌June 27-29, Wuxi:‌ At the 9th NAU Swine Industry Conference in the DoubleTree by Hilton Hotel Wuxi, ZJNF drew numerous visitors to its booth (B4) with its star products, facilitating exchanges and collaboration. At the awards ceremony of the Henan Forum, ZJNF's comprehensive pig farm epidemic prevention solution was awarded the "‌Excellent Equipment for Intelligent Pig Farming Award‌." During the grand finale of the Wuxi Conference, ZJNF received the "‌2025 Golden Classic Brand Award‌" for its full-cycle intelligent farming solution. These dual accolades reflect ZJNF's precise understanding of industry trends. The company addresses the dual demands of livestock farming: "‌cost reduction and efficiency enhancement‌" and "‌low-carbon transformation‌." After over two decades of dedicated development, ZJNF has integrated the R&D, manufacturing, sales, and service of air purification products, purification consumables, and purification engineering projects. The company not only provides high-quality products but also focuses on delivering ‌customized services‌ and ‌comprehensive support‌ to its clients.

On May 8, 2025, the Global Semiconductor Industry (Chongqing) Expo (GSIE) grandly opened at the Chongqing International Expo Center. As a barometer of the semiconductor industry in the central and western regions, this exhibition covers an area of over 40,000 square meters and attracts more than 800 enterprises to participate. Amid the industry wave of surging demand for AI computing power, intense competition in advanced manufacturing processes, and an 11% annual growth in the global semiconductor market, Shenzhen Zhongjian South showcased its new products and star products at the exhibition. Its semiconductor cleanroom system solution attracted widespread attention. During the exhibition, Shenzhen Zhongjian South, with its core patent (CN202323443866.3) as the technical anchor point, showcased its "Intelligent FFU+ Chemical Filter" dual-core solution, precisely addressing the dual pain points of cleanliness and energy efficiency in semiconductor manufacturing, and injecting new impetus into the industry's green transformation. The intelligent FFU of Shenzhen Zhongjian South builds a dynamic closed loop in accordance with ISO14644 standards. Through intelligent monitoring of 0.3μ m-level particulate matter in multiple regions and adaptive compensation for air volume, it achieves dual control of cleanliness and energy consumption, featuring "millisecond response to over-limit and intelligent frequency reduction when meeting standards". Combined with H14 grade filtration efficiency of ≥99.97%, Create a new clean benchmark of "intelligent control and energy conservation" with zero over-standard risk and 30% energy consumption optimization for high-precision scenarios such as semiconductors and biomedicine.   Shenzhen Zhongjian South drives the innovation of semiconductor clean technology with its core patent (CN202323443866.3), and showcases its "high-temperature resistant filter + chemical filter" dual-core powerful tools at the exhibition. The high-temperature resistant filter directly hits the high-temperature sterilization tunnel/drying room scenarios in pharmaceutical factories, efficiently intercepting particles such as tar, soot, and dust, and building a solid clean barrier for high-temperature working conditions. Chemical filters specialize in the treatment of gaseous molecular pollution (AMC) in semiconductor clean workshops. They precisely adsorb corrosive gases in process exhaust gas and harmful substances in fresh air, achieving corrosion prevention and control as well as yield improvement.
