Ideal for Schools, Fabrication Shops, Manufacturing and Production Areas
Cleveland – Lincoln Electric Automation introduces low and high-vacuum Central Systems for weld fume control. Central Systems extract and remove welding fume at multiple points of welding and transport the fume through ductwork to a central location for filtration, helping to keep welding fume away from the operator’s breathing zone and reduce accumulation of welding fume in the surrounding area. Central Systems are an ideal weld fume control solution for schools, fabrication shops and manufacturing and production areas.
Central Systems are typically comprised of eight to 40 extraction arms, ductwork, a filter unit, fan and controls. The main difference between low and high- vacuum Central Systems is the size of the source extraction workzone at the welding arc. Low-vacuum Central Systems have an extraction workzone that is six to15 inches from the fume generation point. In the case of high vacuum Central Systems, the extraction workzone is only two to six inches from the fume generation point.
Additionally air volumes are different. A low vacuum Central System removes a large volume of air with a low transport velocity and system pressure. A high-vacuum Central System draws the air at a very high air transport velocity and high pressure, but at a low air volume.
Lincoln Electric has expertise in both types of Central Systems and can assist customers in the evaluation of their operations and selection of the system best suited to their needs and requirements.
The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) and American Conference of Industrial Hygienists (ACGIH) threshold limit value (TLV) limits.
