This paper deals with measurement of the capture efficiency of REEXS (Reinforced Exhaust System). For the experiment a local exhaust hood was designed with the possibility of working either as a traditional circular exhaust hood or as a REEXS. Experimental measurements were done both for the traditional hood and the REEXS, with the same exhaust flow rate. The results were then compared.The results proved that the main weaknesses of the traditional local exhaust hood can be improved by using REEXS hood.
