Whether you run a marking laser continuously or engrave only occasionally, the right laser fume extraction depends on the process, the material and the amount of dust produced. The Weller Laserline series covers this range with several models designed to work together.
With every laser application, particles and gases are released from the material being processed. If they disperse into the room, they put the health of employees at risk and settle as a film on sensitive components, which impairs the function and service life of the workpiece. A laser fume extraction system captures these emissions right where they arise. This keeps the laser optics free of deposits and the workpiece clean, before the dust can spread through the room at all. The Weller Laserline systems work in recirculation mode and return only cleaned air to the workplace, so a separate exhaust duct to the outside is not required.
The heart of every Weller laser extraction unit is its multi-stage filter system. Depending on the model, a spark trap catches glowing particles, a pre-filter holds back coarse dust, and the compact filter cleans the air through a HEPA particulate filter of class H13 to EN 1822 and a wide-band gas filter. The separation efficiency of the particulate filter is over 99.997%. For marking and engraving with a low level of dust, the compact LL200v is sufficient; for higher dust volumes, the series offers more powerful models. All models run particularly quietly thanks to a brushless EBM-Papst turbine, give an audible and visual warning before a filter needs changing, and can be retrofitted with special filters for cleanrooms or inkjet applications.
Laser cutting, engraving and marking produce fine dust and gases that are hazardous to health and can settle on the workpiece and the laser optics. Without extraction, these emissions spread through the room, pollute the air you breathe and shorten the service life of the optics. A laser fume extraction system captures them directly at the source and helps you comply with the legal requirements for clean air.
The filter system of a laser fume extractor cleans the extracted air in several successive stages. A spark trap catches glowing particles, a pre-filter traps coarse dust, and a HEPA particulate filter and a wide-band gas filter then clean the air of fine dust and gases. Only the cleaned air returns to the work area.
For marking and engraving that produce low to medium amounts of dust, the compact LL200v is a popular choice. As the amount of dust increases, for example during cutting or welding, the more powerful Laserline 400v is the better option. The right model depends on the material, the process and the amount of dust produced.
Yes, some of the Weller Laserline systems can be fitted with special filters, for example for cleanroom applications, for use with inkjet printers, or for other chemical applications where a wide range of gases is produced. This lets you adapt the extraction system to your specific requirements. For personalised advice, get in touch with Weller.
