Abstract
In the process of Painting, it is requested to make clean factory to improve the quality of painting. In a prior measurement result, it turned out that the inflow of the floating dust by the temperatures fluctuate ventilation was a cause of contamination. So, we developed the air curtain for which the wind amount balance was effective to improve air quality in the process of painting. We have extracted the effective air curtain system by a prior analysis by CFD. The system of performance introduced into the real line was obtained the separating and removal effect of 80%.
