Wei, a central air cleaner is a semiconductor used in health technology: Photocatalytic available sunlight as an energy source to activate the semiconductor catalyst to drive oxidation - reduction reaction, and there is no loss of the semiconductor catalyst during the reaction. Sterilization complete: Semiconductor air purification technology can directly organic pollutants hotel fan coil air purifier, completely oxidized to non-toxic materials, without leaving any secondary pollution, fan coil air purifier Which is good, the widely used activated carbon adsorption of contaminants does not decompose, but will transfer pollution. Semiconductor disinfection purification technology has strong oxidation characteristics of certain ozone is difficult to oxidize organic matter such as carbon tetrachloride, chloroform, hexachlorobenzene, can effectively be decomposed fan coil air purifier principle, so it is difficult degradation of organic matter has a particularly good effect, effectively oxidant photocatalytic oxidation of hydroxyl radicals is higher than the common ozone, hydrogen peroxide, potassium permanganate, hypochlorous acid and the like. Long life: theoretically, semiconductor disinfection purification devices life is infinitely long.
