BOFA Is the ‘World Leader’ in fume extraction and filtration and has been designing and manufacturing solutions for over 25 years.
BOFA’s specialized knowledge of fume extraction requirements associated with laser coding,
marking, cutting and engraving applications has enabled them to develop solutions for a variety of manufacturing sectors Including the food, beverage, household, and chemical industries.
In most laser marking applications some form of fume is given off as the laser thermally decomposes the substrate to a greater or lesser degree. This fume is a mixture of particulate and gaseous matter.
Fume from materials such as metal and glass is mainly particulate, the majority of which is less than 1 micron in diameter. Organic materials, particularly plastics, produce much more complex fumes.
