Equipment Details

Low vacuum systems can be source extraction at the arc or general ventilation. Low vacuum source extraction systems draw air at close proximity (6 - 15 inches) to the welding arc. The extraction equipment is designed such that it removes a large volume of air at low transport velocity and low system pressure. The air volume is directly related to the type of capture device used with the low volume system.


  • Easy positioning of extraction arm
  • Minimal maintenance
  • Automatic filter cleaning
  • Custom engineered to meet facility and application requirements
  • Larger amount of air removed from operator’s breathing zone
  • Lower noise level
  • Energy efficient - automatic controls and recirculation



  • Schools with individual welding booths
  • Training facilities
  • Facilities with fabrication of large parts.

1. Extraction Arms - Extraction arms for low vacuum systems are constructed of a hood and hose or hose and tube combination. The arm’s diameter is typically 8 inches; lengths are usually 6, 10 or 13 feet (2, 3 or 4 meters) with boom extensions available. When correctly positioned, the capture capability of adjustable fume extraction arms is suitable for all position welding and cutting. A lamp with arc sensor kit is available for most arms.

2. Ducting - Enclosed pathway for moving welding fume from capture device to filtration unit.

3. Filter Unit
- Lincoln Electric filter units have self-cleaning capability and filter media designed for welding fume. Filters with a Minimum Efficiency Reporting Value (MERV) rating of 16 are available. (Filter efficiency is dependent on process and particulate type and size). A collection bin located under the filter unit provides a convenient means to handle collected particulate. (Particulate should be disposed of according to Federal, State and local regulations). Some filter units may include a pre-separator to protect filter cartridges from mechanical damage due to larger particles.

4. Fan Motor
- When reviewing fan specifications, Lincoln Electric looks closely at: Correctly sizing the fan motor will minimize operating energy costs while providing the correct amount of CFM to meet the system and customer needs.

  • Motor speed
  • Free blowing capacity
  • Maximum noise level
  • Weight
  • Operating Elevation

5. Controls
- Two control options are available on low vacuum central systems – manual or automatic. Either control system can be used with or without filtration.

a. Manual On/Off Control
- Manual control results in the fan running at full speed and 100% capacity regardless of demand when the system is turned on. Manual control has the least expensive installation costs, but high energy usage when compared to automatic control.

b. Automatic Control
- A central system with automatic control uses a variable frequency (or inverter) drive to adjust the fan speed based on extraction need. As the control system senses more welding arcs, the fan speed increases to handle the additional demand. As demand lessens, the fan slows
down. Energy savings can be realized with automatic controls; however, the installation cost is higher than manual controls.


NOTE: Individual welder exposure level should be checked to confirm it is within OSHA PEL and ACGIH TLV limits for the manual or automatic setting used.
