Gravotech - LW2 marking station

Laser exhaust system

Laser exhaust system: clean, pure and safe.
Laser fume extractors guarantee clean and safe work in industrial environment. Their role is to suck up dusts, gases and filter out smells produced during machining. Laser exhaust systems are mandatory for marking, engraving and cutting harmful materials.
  • Accurate
    Without a suitable laser fume extractor, particles will settle between the laser and the engraved items. This phenomenon affects the laser beam and impacts the engraving accuracy. Our laser exhaust system keeps your laser cutter and marker clean and maintains accuracy levels to ensure excellent engraving day after day.
  • Easy-maintenance
    Our laser exhaust systems are designed to optimise access and facilitate maintenance operations. Gravotech’s laser fume extractors, equipped with washable pre-filters, separate HEPA filters, rechargeable carbon cartridges and brushless motors ( = asynchronous), are cost-effective solutions.
  • User-friendly and ecological
    All systems in the range comply with international health and safety legislation and RoHS standards. All contaminants are secured in disposable filters. Only clean and pure air is re-injected into the workshop, ensuring premium comfort for the user.
