When a specialty marking studio in the United Kingdom scaled up high-volume laser marking on plastics and treated metals, it uncovered a hidden production threat: the very process that created its precision products was contaminating its optics and its air. This case study explores how the studio resolved air safety and optical contamination challenges with the KNOKOO FES i200 High-Capacity Fume Extraction System.
The marking and engraving processes on substrates such as anodized aluminum, acrylic, PVC, and composite laminates generated three critical operational hazards:
The studio integrated the KNOKOO FES i200 Fume Extractor into every Galvo marking cell, applying a three-layer engineering approach:
| Metric | Result |
|---|---|
| Odor Neutralization | 100% – chemical odors (PVC/Acrylic) completely eliminated, restoring a comfortable operator working environment |
| Fine Debris Capture | 99.97% – HEPA filtration verified capture of all laser-generated sub-micron particulates |
| Optical Maintenance Reduction | 55% – more than a 50% drop in lens cleaning frequency, preventing premature lens etching and maximizing uptime |
| Suction Stability | Stable high-static suction – consistent flow velocity maintained even under high-residue marking conditions, ensuring predictable performance |
"The KNOKOO FES i200 solved our air quality and optical contamination issues simultaneously. Our operators can work comfortably, and we are saving thousands in lens replacement costs."

For laser marking and engraving workshops handling polymers, coated metals, and composite materials, the KNOKOO FES i200 delivers certified point-of-origin fume extraction that protects both people and production equipment. By combining HEPA-grade filtration, high-capacity activated carbon adsorption, and a rugged vertical flow design, the FES i200 reduces optical maintenance, extends lens life, ensures OSHA-aligned indoor air quality, and keeps high-volume marking lines running at full productivity.
