Work areas must be well ventilated, and inspectors are becoming more vigilant in making sure dust and fume extraction is such that the whole factory doesn’t fill with fumes, affecting welders and other workers not directly associated with the welding operation.
Sometimes the extracting Fume Arms or small hoods can be vented to atmosphere through the wall or roof, but dust or grinding residue should be dealt with (filtered) so as not to pollute the atmosphere, and annoy or affect neighbours.
There is a range of options available which will filter and collect the debris. From simple in line 'Drawer' filters able to deal with a single dust/fume source.
Compact Pulse filters for 2-10 arms are available from stock.
