What Kind Of Dust Collector Should I Use With A Fume Gun? With A Fume Arm?

Fume guns and fume arms require different dust collectors. Following is a brief breakdown of what each device needs on the suction end.

• Fume guns - A fume gun places the extraction point right at the point of fume creation, ensuring efficient capture. The nozzle is small and handles a high vacuum pressure—around 80 inches of pressure. While the pressure is high, the airflow is modest—around 60 CFM (cubic feet per minute), versus a fume arm’s 600-1,200 CFM (based on arm diameter). Fume guns work well with hi-vac (high-vacuum) equpiment like RoboVent’s Hi-Vac unit or the ProCube unit.
• Fume arms - A fume arm is much less particular than a fume gun and can be attached to a wide variety of dust collection equipment. Fume arms work with a lower pressure and higher airflow than fume guns. They might be found on portable dust collectors, such as RoboVent’s PowerBoom collector. They can also be attached either to standalone dust collectors or plugged into a ducted, centralized system.
