Dynaflow's R&D; team combines the optical cavity technology of the laser with the germicidal and disinfection properties of deep UV light. The wavelength of UV light chosen is very close to the absorption spectrum of proteins, which can greatly improve the efficiency of disinfection. Deep UV laser disinfection is a physical disinfection technology based on optical principles, which completely avoids the disadvantages of chemical disinfection methods. At present, the deep ultraviolet laser extermination technology can be on the surface of the object and the air of the virus, bacteria for rapid extermination. According to the inspection report provided by China Academy of Metrology, Dynaflow's deep UV laser extermination equipment has an average efficiency of over 99% for bacteria in 1s and 91.8% for new coronavirus in 3s. The deep UV laser extermination equipment is suitable for logistics, meeting rooms, hospitals, families and other scenarios.
