The Nederman Eliminator 840 and 841 Automatic Start/Stop are the best of the best. There is nothing more to say other than this brand new 841 automatic start/stop fume extractor seen in the photos has the best suction, design, quality, usability and overall performance of any 'briefcase' style portable fume extraction unit.
The auto start/stop feature works using a 'reference lead' (mini crocodile earth clamp at the end of the copper cable) which clamps to the metal work piece where the welding machine is earthed, then the 841 fume extractor pick ups the current when the welder arcs up, then the auto start/stop activates the suction. The idea is that the extractor doesn't have to been turned on continuously if the welder isn't welding, and if the machine is far away from the operator whilst they're in an awkward hard to reach place, then it's ideal to not have to keep going back and forth to switch the machine on and off manually. It's actually pretty clever stuff.
Our fume extractor equipment also has a magnetic nozzle assembly on the end of the hose to allow for quick and easy clamping.
