[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] strength abroad cleanroom demanding on several criteria such as the United States cleanroom requirements yes. 300lx artificial light has a good effect, when a higher degree of fine artifacts clean plant engineering, 500x also permitted. For red light to places, such as the electronics industry lithography plant engineering, the illumination is generally (25-501x) may allow for higher illuminance decontamination of natural light, and therefore it is advantageous to work, so in the future clean room both artificial light illumination using natural light also may be promising, which is to save energy and the emergence of a trend.
