Article: Proper Air Filtration — See No Evil, Hear No Evil (Metal Forming Magazine)

Noise and haze can add stress unnecessarily to already taxed welders and machine operators. Why inhibit their productivity when all that’s needed is a well-designed and properly installed air filtration system? This was precisely the case at this agricultural equipment OEM.

Welders and cutting machine operators welcome new technology that makes their days more productive, safe, rewarding and enjoyable. Such joy and appreciation can quickly subside when improved productivity and throughput comes with added shop noise and dirtier air.

Such was the case at agricultural industry supplier Fast Manufacturing of Mountain Lake, MN, a manufacturer of pull-type sprayers and liquid fertilizer application equipment. As the market for such equipment has surged since 2008, according to Fast general manager Clay Roll, so has the firm’s fabrication and welding capacity.

In 2009 the firm added 4800 sq. ft. to its main fabrication building, which houses 25 manual arc welding booths. In 2011, a second adjoining production facility welcomed a new plasma arc cutting table, and in January 2012 a new 4500-W laser cutting machine. Finally, in December of 2012 the firm acquired a second 4500-W laser cutting machine, replacing the plasma table. A third adjoining building features a 4000-W laser cutting machine designed to cut tubes and structural sections. Fast processes structural steel plates and sheets from 16 gauge in thickness to 2 in., and square tubes ¾ in. to 10 in.

Dust/Fume Collectors for Laser/Plasma Cutting

CNC plasma tables and laser tables generate molten metal and smoke that is pulled down through the grate. The smoke is then removed through the duct work and filtered through the dust collector.

In these applications, a channel baffle inlet should be used to help deflect any sparks that make it to the collector. For safety, spark detection and suppression should be considered in extreme cases. Fire retardant cartridges should always be used in this application, as well as sprinkler heads in the collector itself.

Explosion vents should also be included when cutting aluminum. The collector should be located outside. It is best to check with your insurance carrier and follow the NFPA 654 Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particle Solids.
