Welding is a major metal joining process used in industry. Despite of various advantages of welding there are hazardous effect to human health due to welding fumes. Welding fumes consist of metal oxide particles and various gasses like carbon monoxide (CO), carbon dioxide(CO2),nitrogen oxides(NOx) and ozone. These particles are directly inhaled by operator which causes various health problems. So there is need of a device which extracts particles from welding fumes. Fume extractor removes these particles from welding fumes by using activated carbon filter and expanded Polytetrafluroethylene (ePTFE) filter. As particles up to 0.5 micron are extracted, it results into clean and healthy surroundings.
