Weld Fume Extractors

What are weld fume extractors?

Weld fume extractors are specialized ventilation systems designed to capture and filter harmful fumes and particulates generated during welding processes. They help create a safer and cleaner working environment by removing potentially toxic substances from the air, thereby reducing the risk of respiratory issues and other health problems for welders and nearby personnel.

These systems can vary in size and design, ranging from portable units to large, centralized fume extraction systems. They can also be equipped with various types of filters, such as HEPA and activated carbon, to handle different kinds of pollutants. Weld fume extractors can be used in both manual and robotic welding applications and are essential tools for maintaining air quality and compliance with occupational safety standards.

Why are weld fume extractors needed?

Weld fume extractors are needed to keep welders safe and keep facilities compliant with OSHA permissible exposure limits (PELs) for weld fume. By integrating weld fume extractors into your operations, you not only protect your workforce but also make a smart business decision that pays off in the long run. Weld fume extractors are crucial for multiple reasons: 

  • Health and Safety: Welding processes produce fumes that can contain harmful substances like toxic metals and gases. Prolonged exposure to these fumes can lead to serious health conditions such as lung disease, respiratory issues, and even neurological problems.
  • Regulatory Compliance: Many countries have regulations that require employers to protect workers from hazardous fumes. Weld fume extractors help your workspace meet these legal requirements.
  • Increased Productivity: A safe and comfortable work environment boosts productivity. Workers are more efficient when they are not worrying about inhaling harmful fumes.
  • Equipment Longevity: Accumulated fumes and dust can corrode or damage equipment over time. Fume extractors help maintain the condition of your tools and workspace.
  • Better Work Quality: Removing fumes and particles from the air via a weld fume extractor provides a clearer view of the workpiece, allowing for more accurate and higher-quality welding.

What types of fume extractors can be used for robotic welding?

Robotic welding requires heavy-duty weld fume extraction to keep up with high production. 

  • Robotic processes are often enclosed under a hood to prevent fume propagation. The hood may be ducted to an individual dust collector, such as RoboVent Spire™. Alternatively, multiple robotic cells may be ducted to a large centralized dust collector, such as RoboVent Senturion™.
  • For applications that cannot be easily enclosed, on-torch tip extraction, such as RoboVent FlexTrac™, provides a simple and effective solution. These systems collect weld fume right at the source as it is produced. The tip extractor is connected to a high-vacuum dust collection unit like RoboVent FlexPro™.

What types of fume extractors can be used for manual welding?

Manual welding requires a fume extraction system that will keep weld fumes away from the welder’s face. This usually requires a source capture system. Weld fume extractors commonly used for manual welding include: 

  • Fume arms, which are positioned over the weld seam to collect fumes. 
  • Backdraft plenums, which are positioned behind the welding surface to pull weld fumes up and away from the breathing zone. 
  • Fume guns, or extraction torches, which integrate fume extraction into the torch itself.
