Zhehan Filtration is positioned to serve industrial filtration needs. In its early stage, it focused on the research and development and production of metal wire mesh filtration elements, with products such as stainless steel sintered mesh, which are applied in fields like petrochemicals. In the early stage of starting a business, relying on the mature wire mesh industrial chain in Anping County, the first batch of orders were delivered. The market was opened up with "stable quality and flexible delivery time", laying the foundation for subsequent development.

•  

  In 2010, the scale of the wire mesh industrial cluster in Anping County began to take shape. However, the products were mainly traditional screens and guardrail nets, and high-end filtration equipment relied on imports. At that time, environmental governance and manufacturing upgrading had an urgent need for high-precision filtration. Domestic enterprises urgently needed localized filtration solutions, which provided market opportunities for later companies like Zhehan Filtration to enter the filtration field.

•  

  In 2014, it grew from a small processing factory into a modern filtration solution service provider integrating R&D, production and sales, witnessing the transformation of China's filtration industry from "manufacturing" to "intelligent manufacturing", and has become a typical representative of the upgrading of the wire mesh industry in Anping County.

As industrial customers' demands for filtration efficiency, corrosion resistance and service life increase, the limitations of traditional metal wire mesh products are gradually emerging due to the inability of a single material to adapt to complex working conditions and the backward surface treatment process that is prone to clogging and corrosion.

• In 2015, the "multi-layer composite sintered mesh" technology was broken through. Through the layering and sintering of metal meshes of different mesh sizes and materials, gradient filtration was achieved. The product accuracy reached 5μm, with a temperature resistance of 800℃, and it replaced some imported high-end filter elements.

• In 2017, laser cutting and automated welding equipment were introduced to achieve precise forming of filter elements, increasing production efficiency by three times and reducing the defect rate to below 0.3%.

• In 2020, the "Customized Filtration Solution" service was launched, providing full-process customization from material selection (316L stainless steel, Hastelloy, etc.) to structural design for customers' working conditions (such as chemical corrosive media, food-grade filtration requirements), and the customer repurchase rate increased to 65%.

Technological breakthroughs have enabled Zehan Filtration to quickly open up the market, deeply engage in filtration, and empower the global industrial green transformation

• In 2020, the company passed the ISO 9001 quality management system certification

• In 2021, the company launched the "Going Global Plan", and its products passed CE and SGS certifications, being exported to Southeast Asia, the Middle East, Europe, America and other regions

• In 2025, Zhehan Filtration will fully expand its overseas market, hold special overseas ordering conferences, and accelerate its international layout.
