What kind of dust collector is used with an extraction arm?

An extraction arm or fume arm must be connected to an exhaust system or dust collector that provides the airflow required to pull contaminants into the fume arm. Sometimes, a fume arm is connected to a simple exhaust ventilation system, which uses a fan to pull air through the extraction arm and exhaust it to the outside. More commonly, they are attached to a dust collection or air filtration system. A cartridge dust collector is commonly used for applications like welding that use fume arms to collect contaminants at the source. A cartridge collector filters contaminants out of the air and returns clean, filtered air to the facility or the outdoors. 

• A centralized dust collection system may be ducted to multiple extraction arms and other dust- and fume-creating processes. A centralized system with an industrial dust collector such as RoboVent Senturion™ is an advantage for shops with a large number of weld booths or a combination of welding stations and other applications requiring dust control, such as robotic cells. 
• For individual welding stations or small shops, an all-in-one unit that combines the fume extractor with the extractor arm is a simple and versatile solution. The collector may be a portable unit, mounted to the wall or ceiling, or floor mounted.
