The UV sterilization oil fume purifier is a catering environmental protection device that combines efficient oil fume purification with deep sterilization functions, specifically designed to address issues of kitchen oil fume pollution and bacterial growth. Its core utilizes a dual purification technology of ‘high-voltage electrostatic + UV-C ultraviolet’. Oil fume is first intercepted by a pre-installed metal filter to capture large oil particles, then enters a high-voltage electrostatic field where ionization captures fine oil particles and converts them into oil droplets for discharge. Finally, it is irradiated by a UV-C ultraviolet lamp with a wavelength of 253.7 nm, which can quickly destroy the DNA structure of bacteria and viruses, achieving a sterilization rate of over 99%.
