The real low-altitude direct-discharge purifier is four-stage filtration, and the purification effect is much higher than that of high-pressure electrostatic fume purifier. The product can automatically adjust the working voltage, and the operation is simple. In recent years, the country has been advocating low-carbon environmental protection. In view of the increasingly strict kitchen oil fume purification market in catering industry, Beijing Xinyuelan Environmental Protection Technology Co., Ltd. launched a low-altitude photolysis electrostatic oil fume purifier in Beijing, which adopts the principle of aerodynamic centrifugal force for primary treatment, advanced ultra-high voltage electrostatic treatment technology for secondary treatment, light wave decomposition of oil fume for tertiary treatment, and the self-developed special equipment structure, so that the purification efficiency of photolysis electrostatic low-emission oil fume purifier can reach smoke-free emission, thus achieving complete visual inspection. Its biggest technical feature is that it can meet the high emission requirements, and it is completely invisible to the naked eye and can't smell irritating smell. So as to meet the requirements of oil fume purification and low-altitude direct exhaust in sensitive areas.
