This paper focuses on investigations of capture efficiency of pollutants with the use of the reinforced slot exhaust system (REEXS), which is known as the Aaberg exhaust hood. It is a traditional slot exhaust hood equipped with an air supply jet that intensifies exhausting along the axis of the exhaust hood. By an adjustment of the air supply quantity, the reinforced exhaust hood can operate in traditional or reinforced modes. Two main cases were investigated – the first was with a free space in front of the slot exhaust hood, the second case was with the workbench at the level of the lower edge of the exhaust opening. Influences of the workbench were investigated for the same air velocity in the exhaust opening and with different momentum flux ratios of supplied and exhausted air flows. In both the cases the capture efficiency was measured by the tracer gas method. The carbon dioxide was used for that purpose. From measurements of the capture efficiency it was concluded that the use of the workbench has a positive influence on the capture efficiency area.
