In addition to ventilation, the most important function of the fresh air system is to filter pollutants in the air. Therefore, the filter of the fresh air system is the most important part of the entire system.
According to grade, principle and material, the filters of the fresh air system are classified into different categories. The ptfe industrial fresh air filter material is made of polytetrafluoroethylene (ptfe) material through mixing, extrusion, extrusion, calendering, bidirectional stretching and other special processes. Craftsmanship.
The porosity of this membrane can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um. The high-efficiency filter paper has high and low temperature resistance ( -200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
