China's first dust-free vacuum system was inspired by Typhoon Cyclone. Our French engineer, Mr. Ness, has studied this technology for three years and finally successfully developed it and applied it perfectly in our products, which has been patented. This technology is already used in our S, C, and E series devices. Its exquisite design and excellent performance have won the praise of many customers. More and more customers have seen the revolutionary vacuum design in the industry, and some of them have traveled to China to buy Bcam.
