Anyone ever hear of this or better still have any experience with it, FILTAIR® Capture 5 Fume Extraction System http://tinyurl.com/y96e4und. I'm buying equipment now and have been for the past 4 years, formerly in the welding shop for 25 years. I was approached to purchase a few of these units, almost seems too good to be true, able to capture smoke from 5' away? Anyone have any thoughts, btw, CAN$ 13K each............Mike
