The Fume Extraction Unit for Your Laser Marking Station 

Regardless of whether your laser marking process is annealing or ablation, your frequent by-product is fumes released as the intense heat of the laser breaks molecular bonds. The exact composition and volume of this off-gassing vary, depending on the material being heated – but it often contains toxic VOCs: 

• Laser-marking metals kicks up metal oxide particulates; 

• Processing plastics can release corrosive, carcinogenic vapors and soot; 

• Vaporizing coatings off surfaces poses a risk of releasing dangerous heavy metals like lead, chromium, or arsenic.  

Refer to the Safety Data Sheets (SDS) to be aware of the hazardous decomposition products that form when the material is exposed to extreme heat.   

But, while the makeup of the off-gassing may vary, one factor is common – it’s harmful to the operators’ health and the machinery with sensitive optics and electronics. 

Fume extraction is the solution. Through a multi-layer filtration system, fume extraction units effectively capture harmful gas and particulates during the laser marking process.  

At Beamer, we specialize in enclosed laser marking stations that carry a CDRH Class I safety rating. What does that mean for you? It means the laser radiation is entirely contained behind a laser-safe viewing window, and built-in safety interlocks ensure the laser can never fire while the station is open. 

However, a Class I rating only covers optical radiation – it does not regulate air quality. Fume extraction is actually completely separate from the Class I rating – which is why we handle it proactively. Through our multi-year partnership with TBH, we equip our systems with premium, multi-layer filtration units. While our enclosures protect your eyes, our TBH filtration systems protect your lungs, providing a truly safe, clean breathing environment for your entire team.
