Freestanding filtration system supplements existing source-extraction system

Lincoln Electric Automation offers the Circulator™, a freestanding general filtration system for weld fume control. Suitable for manufacturing and fabrication facilities that have obstructions for ductwork, such as overhead cranes and large amounts of infrastructure, the unit is intended to supplement an existing source-extraction system.

The system reduces the amount of dust and dirt in the work area and supplements natural and forced ventilation to help reduce the overall concentration of welding fumes in the workshop.

Its Green-Drive™ control system uses a pressure sensor to monitor operations continually, and it automatically adjusts airflow to maintain required performance levels. This can result in energy savings of up to 50 percent and increased filter life of up to 30 percent over traditional on/off systems, according to the manufacturer.
