Extraction Arm Options
“Typical options when selecting an extraction arm”
Multiple material testing machines generate a lot of dust and control is provided with fume and dust extraction arms.
A standard extraction arm has tube-shaped arms or a full hose body. As standard a hood is attached on the source capturing end. Other standard features include external joints, grab handle for the hood, shut-off damper, spring shocks, wall bracket and connection collar, but there are also various accessories that can be added to better suit the arm for specific applications.
Extraction Hood
The hood is available in different shapes, sizes, and materials. Depending on the application, a light for the hood can be added. The basic type of hood has a circular shape and is useful for close range capture. Besides the basic type, hoods are available in domed, square mesh, and flat screen.
Hood selection is determined by application. In the lab, for instance, square hoods are used for collecting heavy gases, while dome types are used for sources having wide emission ranges. Some extraction arms also come with interchangeable hoods for specific applications.
Cross-contamination in cosmetic and pharmaceutical manufacturing applies dust control with extraction arms.

Suction Nozzle
Extraction arms can also be fitted with suction nozzles. Often used on laboratory arms, the suction nozzle allows you to get as close as possible to the source without disrupting the work. These work extremely well for harsh environments.
Fume Arm Mounting Options
Extraction arms can be mounted on a floor stanchion, tabletop/benchtop, wall, or ceiling. For hanging arms, typically, the standard mount is a wall mount. When a wall is not accessible or can’t support the arm, there are two options for mounting a hanging arm: 1) floor stanchion or 2) ceiling mount. Floor stanchions allow the arm to be supported by a steel beam that is mounted to the floor. Floor stanchions are tall but narrow so taking up floor space isn’t an issue. Ceiling mounts allow the arm to be supported from above. Typically, the ceiling mount would mount above the false ceiling (in some cases there isn’t one) to the Unistrut or cross beam. The ceiling bracket length can range from 20” up to 108” for ceilings that are higher.
