Hubei Felt Filtration Engineering Technology Co., Ltd. is a high-tech Sino-foreign cooperative enterprise registered with the provincial industrial and commercial bureau. It is one of the earliest high-tech companies in China to promote internationally advanced ultrafiltration and microfiltration technologies. Felt Company has strong technical capabilities and has experts who were among the first in the country to study ultrafiltration technology. Over the years, it has served hundreds of enterprises nationwide and received high praise.

In order to meet the needs of the development of China's pharmaceutical industry, we established the Felt Filtration Engineering Process Technology Research Institute. Based on the introduction of advanced foreign technology, we have developed various series of large-channel clarification filtration systems such as Felt FLT(Z)(F)(N) that are suitable for China's national conditions. It features reasonable design, convenient operation, resistance to clogging, strong regeneration capability, no leakage, durability, and a long service life of the filtration medium, complying with GMP standards. It can be widely used for clarification filtration of materials in pharmaceuticals, biological fermentation, food, condiments, cosmetics, etc. Additionally, we provide comprehensive technical services such as filtration process design, small sample experiments, and scale-up production final tests according to the characteristics of customer products.

Hubei Felt's ultrafiltration technology uses advanced foreign filtration membranes, which are a type of selective membrane filtration technology at the nanometer scale. Ultrafiltration can achieve the removal of impurities (bacteria, large particles, fine particles, colloids, tannins, proteins, polysaccharides, etc.) and improve the clarity of medicinal solutions. It is particularly widely used in traditional Chinese medicine injections (such as compound Danshen, Da Qing Ye, Siberian ginseng, Shuang Huang Lian, Deng Zhan Hua, Hong Hua, Xiang Dan, Yu Xing Cao, Huo Xiang, Yi Mu Cao), large infusions, oral liquids, as well as traditional Chinese medicine compound polysaccharide nutrient solutions and heat-clearing detoxifying ginseng essence powders. After using ultrafiltration membrane technology, its products have better clarity, stability, content of target substances, heat sources, and allergenic substances compared to other methods. The unique filtration system production process of Felt Company is superior to older processes: it has a shorter production cycle, simpler process route, stable product content with high quality; production equipment is simple and convenient to operate with low investment and fast material input-output ratio and high efficiency. It is a filtration system for domestic pharmaceutical factories' GMP transformation.

Hereby, Felt Company sincerely welcomes friends from all walks of life at home and abroad to visit our company for inspection, communication, cooperation, and common development!
