Arnold, Missouri Fume and Dust Extraction Arm Systems
Arnold 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.
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.
Arnold, Missouri 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.


Arnold, Missouri Fume Extraction Arm Mounting and Supports
Fume extraction arms are continually moved, extended, and rotated, requiring them to be rigidly supported and mounted securely. A few factors affect mounting location: 1) the location of the fume source, 2) the coverage area for where the arm is used 3) the central system duct where the fume arm is connected.
Mounting options include:
Wall Mount - With duct systems running against a wall, mounting the arm (s) with brackets secured to a block wall or column is typical. If the central system duct is along the ceiling, on an outside wall, or mid-wall, there are designed brackets to fix the arm in place.
Bench Mount - Exhaust duct running along the floor allows mounting to a bench or tabletop. This mount has a standard option bracket for attaching the arm. Another standard bench mount is on a portable air filter or dust collector.
Ceiling Mount - Mounting the arms in the ceiling is an option if joists are present. A support weldment could be fabricated if a ceiling mount is a requirement. For low-weight short arms, the installation contractor can fabricate a wood fixture.
Stanchion Mount - When arms are located in the center of a facility having high bay areas, a stanchion will allow the mounting of an arm and hold it rigidly in place.
Arnold 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. Arnold, Missouri Laboratory bench mount arms are an option and are available in three and four-inch diameter tubes up to six feet in length.
- Arm diameters include 2", 3", and 4", and arm lengths include 25", 30", 39", 45",51", 53", 59", 65", 75", 79", 83", and 104".
- Wall brackets, ceiling brackets, and table mount brackets are available.
- 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.
- Market-leading low-pressure drop
- Optional fume exhaust fans in aluminum, carbon steel, or PVC.

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

Arnold, Missouri 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.
- Shut off dampers built internally.
- 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'.
- Optional fume exhaust fans in aluminum, carbon steel, or PVC.
- Low-pressure drop

Arnold, Missouri Fume Extraction Arm Optional Accessories
Fume extraction arms have optional accessories that include:
Ceiling Mount - For applications where arms are mounted/supported by the ceiling. The ceiling bracket varies in height depending on the height of the hard deck or Unistrut.
Tube materials – For those arms using tubing, construction materials include painted steel, aluminum, stainless steel, P.P., or PVC. Extraction arms that use flex hoses can use clear, fire retardant, high temperature, or anti-static hoses.
Hood lights – Lights can be attached to the arm hood to provide better vision at the work point. Often used in welding applications.
Nozzles - To get even closer to source capture, suction nozzles and flexible suction nozzles are available.
Custom hoods – To maximize fume capture, standard circular or scoop-shaped hoods can be changed to a slotted design, rectangular, flat, or custom fabricated.
Floor Stanchion - When the ceiling is too high, or there are no walls, a floor stanchion can be used to mount the arm.
Wall Mount - A wall bracket designed to mount the arm to any wall or beam within the facility.
