Miller Electric Mfg. Co. has introduced the FILTAIR® Capture 5 fume extraction system, designed to capture welding fumes up to 5 ft. away from the source. According to the company, this is more than three times farther than conventional technologies.
The system is suitable for applications in heavy equipment manufacturing and general fabrication, as well as in maintenance and repair operations. It can accommodate fume from SMAW, FCAW, GMAW, and GTAW processes.
The fume extraction system features the company's ZoneFlow™ technology, which creates a capture area up to 4 ft. wide and 5 ft. deep. It operates by way of a negative-pressure zone that extends the weld fume particulate capture distance. Air enters the arm at a standard fume-capture rate of around 900 CFM, while the technology also moves clean, filtered air out of the arm at about a 90-degree angle. This action creates a negative-pressure zone, which funnels the fume particulates toward the center of the arm to help maximize the fume capture.
