"All plastics except for acrylics, when you cut them, make roughly 80% particulate and 20% gas. With acrylics, it's the other way around. It's about 40% par- ticulate and 60% gas, so you'll go through your carbon filter faster than you would your particulate-arresting filter." Shops who offer dye-sublimation, wide- format, and UV printing can also benefit from fume extraction, but it takes a little extra work to find the right machine and setup. "(These disciplines) are a different animal because they have different chem- istry," Baird says. While laser fume extrac- tion involves dry chemistry, disciplines like sublimation are wet chemistry that involves moisture, so he advises shops to consult with the manufacturer to ensure they're us- ing the proper filtration. Some wide-format and sublimation printers come with a tap designed to hook up to the fume extractor. Still, parties agree that these aren't a standard feature on all brands. Consulting with the manufacturer on this apparatus is a good starting point since decorators must ensure the two ma- chines connect seamlessly.
