By referring to the international newly popular air conditioning catalysed by nanometer light, the company researches and develops this new air purification technology.

   Principle: taking nanometer TiO₂ as catalyzer, under none ozone ultraviolet rays of specific wavelength, hole (h⁺) and electron(e^-) appeared on surface of solid TiO₂. The hole oxidates H₂O; the electron electronates O₂, and active hydrogen radical reaction occurs, which could decompose organic nutrient matter required during growing and reproduction of bacteria, and could destroy and inhibit the growth of bacteria. Meanwhile, organic compounds and other harmful gases could split into H₂O and CO₂.

   Air purification filter, catalyzed by TiO₂ light, in which the TiO₂ catalyzer compounded onto carrier of various structure materials by special technology. So it is of light-catalyzed function. Then it is designed by specific environmental requirements. This technology is of wide application scope, strong applicability, and is widely used in purifications fields, such as air supply system of central air conditioning.

   Taking patent technology of one kind of air purification filter as core unit, the company researches and develops such three series products as GMF, GMB and GMZ. And it was tested by National Authority Organs. The product have broad-spectrum sterilization function to surrounded air of air conditioning environment , with 97.0% or above rate of sterilization, 91.0% or below rate of decomposition of air of organic compounds . And it could curdle viral protein, decompose and kill bacteria. The product is in the lead home according to results of investigation.
