This series oil fume purifier adopts two-waveband ultraviolet lamps to eliminate the oil fume and odor. Pre-filter removes large oil particles and protects the lamps. Patented two-waveband UV lamp matrix (254nm&185nm) can effectively change oil fume particles to smaller one, and remove the odor with ozone. Specifically, 254nm waveband quickly breaks the oil particles to smaller one. At the same time, 185nm waveband generates ozone, and oxygenizes oil particles, volatile organic compounds (TVOC) and odor to form white powder. The total oil fume removing efficiency can reach above 95% and the odor removing rate is above 80%.
