The FILTAIR® 6 in. x 7 ft Standard Fume Extraction Arm is a pre-assembled fume extraction arm that offers external adjustments to minimize airflow resistance. This results in a stronger cfm (airflow) for improved performance. The arm is specifically designed for wall, pedestal, or column mounting. To achieve a comprehensive weld fume capturing solution, it can be easily connected to the FILTAIR® SWX or Centralized system, as well as other competitive equipment.
