Ventaire’s self-supporting fume arms are the premier solution for exhausting welding fumes from the work place. The SIFA fume arm support brackets are located outside the air stream allowing for unobstructed airflow through the entire arm and provides minimal pressure drop compared to internally supported fume arms. Articulation of these arms is convenient, simply performed by grabbing the handle located on the inlet hood. The SIFA fume arms can be ducted to a central exhaust fan or provided with a direct mount pressure blower. The high-quality construction of Ventaire’s SIFA fume arm provides years of use with minimal maintenance.
