In the 1950s and 1960s, in order to meet the special requirements of low wind speed in the frozen food industry in the world and China, wind ducts made of cloth, also known as cloth bag ducts, appeared.
Due to the lack of emphasis on fiber permeability, it was impossible to match the fan, resulting in poor air supply and problems such as air blockage and fiber life, which gradually led to the disappearance of cloth air ducts.
With the continuous innovation and development of world fiber material weaving technology, the Durkeesox ducts that can weave the required accurate permeability and other material properties, began to appear. By the 1980s and 1990s, sox ducts were rapidly developing in various industries in developed countries in Europe and America.
Sox ducts are no longer simply cloth bag ducts for air supply, but a system product that matches the air conditioning system by calculating the permeability of fiber materials and accurately designing apertures for air supply.
In 2004, Durkeesox officially named the sox ducts as "Durkeesox" when it was introduced into China.
After nearly a decade of stable development and market promotion, it has independently cultivated markets in various industries and regions of China.
Durkeesox Duct has become a synonym for fiber fabric air distribution systems in China.
