Airflow/static pressure:  23,000 cfm @ 15” s.p.

CFM/Static Pressure:  16,000 @ 16” s.p. each system

Application Solution:  Continuous duty dust collector keeps hood airflow constant because it self-cleans filters while the system operates thereby reducing filter replacement costs and task frequency. The airflow controller with VFD provides constant airflow to fume exhaust arms by monitoring/managing airflow based on system filter pressure drop. The telescoping (not articulated) fume arms are suited for booth-type welding which provides ease of use.

Significant energy savings from reduced hp need and operator breathing zone protection due to constant airflow to fume exhaust arms resulted.
