BOFA's range of ADVANTAGE laser fume extraction and filtration systems are designed for applications that generate particulate and gaseous volatile organic compounds (VOC's) within the Laser Marking, Coding and Engraving Industries.
Cutting of materials such as metals, plastics and textiles are now commonly achieved using lasers. This has great benefits such as fast, clean and accurate cuts that often don't require any additional finishing. Laser cutting does however produce an enormous amount of hazardous contaminants that need to be removed to protect the operator and ensure the quality of cut. As with all laser applications if the fume is not removed at source using LEV (Local Exhaust Ventilation), the fume can blur the laser beam, affecting its efficiency.
A variety of toxic fumes and particulates are generated when different substrates are being lasered. These contaminates are known within the industry as LGAC's (Laser Generated Air Contaminates). LGAC's of different makeup can react in the extreme within the filter separation process. In some instances having high ratio of gases to particulates and visa versa. For example, fume from Nylon when lasered is roughly 80% particulate to 20% gas, where as fume from Acrylic is 90% gas to 10% particulate.
With this knowledge, Bofa have developed the Advantage range of fume elimination systems designed specifically for such a broad base of lasered substrate materials.
