Welding Fume Extractor Polygee's BG750 Fume Extractor is a professionally designed and well produced filtration or purification unit, which requires no filtration media replacement".The extractor features tri-step filtration/purification,**first a metal mesh pre-filtrating the big size contamination;**second a master purification unit ionizing and collecting micro-particles with minimum size 0.01μM and the max efficiency 99.9%;**third an active carbon filtration as the odor-eliminator.Air flow are sucked by the single-Phase turbo fan built-in. Casings are constructed of high-quality mild steel and powder-coated (custom colors available).A high-quality fan is rationally combined, 6-foot/10-foot flexible extraction arms are available.The BG750 includes the motor, circuit-breaker, motor cut-out, electric parts and 18 feet of cable with plug.BG750 with four solid casters is easy to move, repair and other temporary work around the shop or to bring with on service.While the wall or giant machine mounted BG750 is easy to install and fix on the wall or frame, custom designs according to different working situations and applications are available.
