Laser & Printing Fume Extraction
Cost-Effective Extraction Solutions for the Laser Marking, Coding and Engraving Industries.
In many industries, lasers are now an essential tool for cutting, marking, engraving and welding a vast range of materials. Metals are the most commonly worked on substrate, when it comes to lasers, but plastics, paper and wood are also frequently used. These are known within the industry as LGAC's (Laser Generated Air Contaminates).
In virtually all the above operations, some form of fume is given off as the laser thermally decomposes the substrate to a greater or lesser degree. This laser fume is a mix of particulates and gases. Fume from materials such as metals and glass are mainly particulate, the majority of which is less than 1µ (micron) in diameter. Organic materials, particularly plastics, produce much more complex fumes. Most of the particles are spherical, and roughly 90% by wieght are less than 1 micron in diameter. This makes them Respirable and must be removed from the working area as they are known to cause Bronchial or Lung damges. Additionally, some materials have other specific groups e.g. PVC polymers generate HCl, 2-component epoxy polymers yield amines and PET generates THF. Laser printing on wood presents its own issues with the potential for fires and respiratory problems, so it is important to install extraction solutions that are fit for purpose.
The gaseous organic compounds produced are known as Volatile Organic Compounds (VOCs). The VOC's often produced in a laser fume are:
- Aliphatic Hydrocarbon such as: Alkane and Alkene.
- Aromatic Hydrocarbons such as: Benzene, Toluene, Xylene.
- Aldehyde such as: Formaldehyde.
- Polycyclic Aromtic Hydrocarbons such as: Benzo(a)pyrene.
At Vodex, we understand that there is a broad range of materials and that it is important to produce solutions for our clients that can manage the threats accordingly. Check out our More Info Page on LGAC's.
