Oct. 26. 2024 00:00:00

On October 26, 2024, Shijiazhuang Chentai Filter Paper Co., Ltd., on behalf of China’s engine air filtration industry, led the formulation of the national standard “Nanotechnologies—Nanofiber Media for Air Filtration—Technical Requirements” (GB/T 44793-2024), which will beimplemented on May 1, 2025.


Nano-National Standard Release Chentai is the main drafting unit

Significance of standard formulation

This standard specifies such contents as normative reference documents, terms and definitions, technical requirements, and inspection rules with respect to nanofiber filter materials for air filtration. The formulation of this standard promotes the standardized development of nanofiber filter material technology, and at the same time provides a basis for regulation by regulatory departments, and promotes the wider promotion and application of nanofiber filter materials in the filtration industry.

Chentai nanotechnology

Chentai is a company that can produce both nanosubstrates and nanofibers. Chentai leverages its own equipment, processes, and formulas to make technological breakthroughs at the forefront of the industry. With the capabilities of independent experimental testing and application testing, the Company is currently an exclusive supplier of air filter materials for domestic OEMs.


The nanoelectrospinning technology canleveragethe substrate of new nanomaterial to create nano-compoote products with high efficiency, low resistance and strong power. The average diameter of electrospun nanofibers is less than 200nm, which is one hundredth of the diameter of wood pulp fibers. The length and surface area of 1g200nm nanofiber can reach 300,000 kilometers and 1,000 square meters respectively. This nano feature can greatly improve the filtration quality, reduce the maintenance cost of filters, relieve the emission load, and meet the National VI emission standard.

 In the next 3-5 years, Shijiazhuang Chentai Filter Paper Co., Ltd. will continue to accelerate its comprehensive innovation in an all-inclusive manner, with technological innovation as the core, and continue to develop in depth and breadth in the field of filter materials, with a view to, through high-standard R&D manufacturing as well as high-quality services, becoming a benchmark in this field.
