Fume and Dust Extraction Arm Systems in Twodot, Montana

Twodot Fume industrial exhaust systems are designed to capture smoke, fume, dust, high-temperature air, and corrosive gases. These "pollutants" are ducted to an air cleaner (purification system) before discharge to the outside or returned to the workspace. Capturing air-entrained materials is best accomplished at the emission source, defined as source capture.

Twodot, Montana Fume extraction arms with hoods or suction nozzles are the number one tool to maximize source capture efficiency. They capture the contaminated airstreams while getting close to the source without disrupting or slowing down the work process or collecting too much useable product. When the task or workpiece is difficult to access, in an isolated area, or along awkward points on an assembly line, extraction arms are a proven solution for maximum particulate, smoke, and fume collection.

Multiple arm designs are available depending on the airstream constituents. The parameters evaluated are temperature, explosivity, corrosiveness, and particulate, all factors determining the type of arm that should be selected for a process application. Matching your expected exhaust volume and arm useage with the required exhaust CFM, pressure loses, and airstream being captured is what we do. SysTech has successfully applied extraction arms for over thirty years and will assist with the correct selection for your process.

Twodot, Montana Weld Fume Extraction Arm

The demand for weld smoke extraction arms is always high and mandates an arm category. Depending on the application, different designs use either smooth wall or flex hose tubing. Both designs use external positioning joints and a hood with an internal adjustable damper. The units are typically wall-mounted but have ceiling and floor support bracket options. Arm diameter options range from six to eight inches, and arm lengths vary from three feet up to thirty-six feet. Personal weld fume packages include a single extraction arm, exhaust fan, and air filter.

  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Standard units include a wall bracket. Ceiling mount options are available.
  • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', 14', 16', 23', 30', and 36'.
  • Shut off dampers built internally.
  • Low-pressure drop

    Twodot Telescopic Fume Extraction Arm

    Telescopic extraction arms are designed to fit into confined spaces. They are used for those applications when the operator wants to "compress" the arm out of the way and pull it back to a working position. The unit will mount on the ceiling, wall, or floor stanchion. There are optional designs from which to choose. There is an arm with a ridged flex hose in six or eight-inch diameter having an operating range of seven feet to almost ten feet or a thin-walled tube design that is available in five-inch diameter and can telescope three feet out to seven feet. Both telescopic arm options would include a manual damper.

    • Powder coated steel wall bracket is standard
    • The hood is powder-coated aluminum and includes a grab handle and shutoff damper built within
    • Arm diameters are 6" and 8", and the operating range (compression) is 4' to 7'.
    • Black hose rated up to 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
    • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
    • Internal is telescopic
    • Swivel base

    Twodot Laboratory Extraction Arms

    The laboratory extraction arm is comprised of thin-wall anodized aluminum tubes with polypropylene swivel joints. A frequent option selection is all polypropylene construction with stainless steel airstream components for highly corrosive airstreams. Additionally, these arms may be constructed of conductive polypropylene material for spark resistance and ATEX-rated explosive applications. Arm tube diameters range from two to four inches, and arm lengths range from two feet up to eight and a half feet. Arms can be paired with a wall or ceiling bracket, several optional hoods, or a suction nozzle. Twodot, Montana Laboratory bench mount arms are an option and are available in three and four-inch diameter tubes up to six feet in length.

    • Various hood options for more efficient source capture include dome hoods, square hoods, flat screen hoods, metal hoods, and suction nozzles.
    • Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.
    • Wall brackets, ceiling brackets, and table mount brackets are available.
    • Market-leading low-pressure drop
    • Arm diameters include 2", 3", and 4", and arm lengths include 25", 30", 39", 45",51", 53", 59", 65", 75", 79", 83", and 104".
    • Optional fume exhaust fans in aluminum, carbon steel, or PVC.

    Economical Industrial Extraction Arms in Twodot MT


    These extraction arms serve a similar function as the general-purpose extraction arm but are constructed with a flexible hose instead of metal tubing. This arm has cost savings, but some optional features are unavailable. These arms were designed for light-duty, intermittent applications and have limitations on some airstream constituents. Importantly, each application is reviewed upfront by SysTech will guide you through the selection process safely. Hose diameter alternatives range from four to eight inches, and arm lengths range from five to thirty-six feet. The standard hose material is blue PVC or white PVC with an option for PE-coated polyamide fabric for mild corrosive applications. Custom sizes can be designed using various parts for different arm models combined to make a new arm design.

    Features and options:

    • Arm diameters include 4", 5", 6", and 8", and arm lengths include 5', 7', 10', 13', 16', 23', 30', and 36'.
    • High positional stability
    • Hood designed for maximum capture efficiency and extraction
    • Lowest possible pressure drop, which helps save energy and lowers sound levels
    • Lightweight construction balanced by two gas springs.
    • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
    • External arm support
    • Unique ease of maneuverability
