PENGARUH EJEKTOR HASIL RANCANG BANGUN TERHADAP PENGURANGAN GAS KARBON MONOKSIDA DAN DEBU TOTAL DI DALAM RUANGAN PENGELASAN

Abstract

In this study, the investigation of the effect of the ejector’s performance on the reduction of air pollutants in thewelding room was carried out. This is done once gas and dust particles comes up during welding. The measurement of airpollutants is carried out in two conditions. Firstly, it is done during welding with no ejector running and secondly, whenthe welding and ejector are simultaneously running. the measurements taken are carbon monoxide (CO) and total dust(Total Suspended Particulate). the Ambient Gas Sampler is utilized in measuring the CO gas, while the Staflex AirSampler measures the TSP. the results show that when the ejector is run, the carbon monoxide and dust are lowercompared to the situation when the ejector is not run.
