This professional grade fume extractor eliminates from the air unbreathables such as smoke and dust. The powerful blower has a high face-velocity and will remove particulates that are as small as 0.5 micron using standard filters. Diversitech's injection self-cleaning system will reduce the Fred 01-Ts total cost by simply extending filter life expectancy and also improving filter efficiency. The fume tracker™ extraction arm on the Fred 01-T improves fume capture efficiency by detecting the light from a welding arc and repositioning the capture arm over the welding smoke. The fume arm reduces the time spent manually on repositioning the hood, increases productivity and allows welders to focus on the task.
