  • fume extraction dilema...

    can anyone recommend a quality fume extraction system? Miller makes some nice units but non of them have a hepa filter which removes 99.7% of airborne particles. Miller claims it can only remove up to 95%. Problem is that when you weld SS it produces hexavalent chromium which is really only filtered with a heap filter. as i am sure many of you already know hexavalent chromium is carcinogenic. I have checked with osha and they also recommend a hepa filter when welding SS.

    Lincoln mini flex is a nice little unit which includes a hepa filter but it is a little too small, i would like something on the bigger side with a higher flow rate. has anyone modified a miller extraction to accommodate a hepa filter? Any thoughts on what else is out there?

    Seems simpler to wear a vented mask with the cartridge type filters as apposed to a fume sucker

        Your using a power vented respirator? Or a face mask. The powered ones are battery operated and are really nice to use

          PAPR's are a thousand times better than a standard face respirator...

          that heavy sweaty "Darth Vader" breathing of a regular respirator is hard to take for long periods..

          here is is a page to look at..

          I have used several styles over the years at customer sites... have considered buying one for myself... they have now become more common and mainstream... but still a bit pricey @ about $1500...
          ... this one is at the top of my current WISH list...
