Purification technology: anion negative ion technology method is the use of a certain concentration of air negative ions to purify the air, because the negative ions easily with tiny pollution particles in the air phase adsorption, become charged large ion air purification and disinfection machine Which is better / factories, sink like the surface of the ground, so that the air purification. The technology can more effectively remove dust from the air, Beijing's air purification and disinfection machine, but filling the dust easily adsorbed on the wallpaper and glass, etc., can not be removed from the indoor air purifier much money / quote disinfection, and because commonly used ionizer often accompanied by the generation of ozone. And Wei developed a semiconductor disinfection purification technology can completely avoid the above problem, really fast, efficient and perfect sterilization, decontamination, predict please call contact picture, thank you! VBY-B type of medical air purification and disinfection machine Dongguan Wei an Environmental Technology Limited, the innovative use of semiconductor technology invented at home and abroad, research and design of air disinfecting machines, most sets new air disinfection ionization, ternary semiconductors and lightwave technology integration of products, access to national utility model patents (Patent No: ZL 2014 2 0127492.6) and patents (patent: 201410104779.1) which VBY-B type air disinfection products.
