Extracting particulate matter is important as it is a mixture of solid and liquid micrometer-sized particles. According to the Technical Rules for Hazardous Substances (TRGS) in Germany, particulate matter is considered a hazardous substance and must be monitored regularly with regard to occupational safety so that defined limit values are not exceeded and a distinction is made between inhalable E-dust and alveolar A-dust. Particles in A-dust are so small that they can penetrate the respiratory tract into the alveoli and bronchioles of the lungs. TRGS900 defines the general dust limit values: A-dust = 1.25 mg/m³ and E-dust = 10 mg/m³. Extracting particulate matter is the best protection from these particles.
Process and emission
Finest emissions through work with lasers
Smallest particles e.g. by wave soldering
Automated welding causes smoke particles
Dust-free air to protect sensitive parts
