The aim of that study was to measure the performance of local ventilation for various parameter settings (nozzles and slots REEXS) and to demonstrate the benefit for real working situations.A test cabin was built, to measure the capture efficiency under reproducible cross draughts. Optimised REEXS hoods were used for the experiment : they proved to have a larger capture range compared to the conventional flanged hood. The results were so encouraging that an exhaust installation for 6 welding working places was completed. And field tests are now considered to show the practical value regarding air quality improvement and ease of the working process.
