The high breathability and high interception efficiency of the three-layer and five-layer composite materials enable the vacuum cleaner to not only effectively intercept dust particles, but also allow the vacuum cleaner to maintain low energy consumption, and the material can be washed to restore performance and achieve reuse, with high filtration accuracy. It can reach U15 level or above (99.9995%) or even U17 level (99.999995%), which can fully meet the purification requirements of high-precision electronic product processing workshops such as semiconductors and chips.
The ptfe biaxially stretched film produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency, for some extremely fine particles with a diameter of 0.1um-0.3um , the filtration level can reach H13-U16.
