A work cell assembly such as welding cell assembly and a method for assembling the same is provided. The work cell has a perimeter wall including an upper wall edge defining an open top. A fluid filtration unit draws in fluid from the work cell and removes contaminants. A fluid moving device including an air blade assembly adjacent the upper wall edge and an inlet adjacent the upper wall edge and spaced downstream from the air blade assembly establish therebetween a sheet-like fluid barrier extending across the open top. The fluid barrier is defined by a continuous flow of fluid traveling across the open top for entraining the contaminant and creating a ceiling effect across the open top to prevent escape of the contaminant from the work cell through the open top. The fluid barrier has a narrow vertical extent to prevent disturbance of the fluid in the work cell.
