    General Purpose Akhiok, Alaska Industrial Extraction Arm

    "General Purpose" Akhiok, Alaska Industrial Extraction Arm

    We label these arms a standard issue because they can be universally applied to most fume and dust extraction applications. The general-purpose arm is suitable for capturing smoke, dust, or any non-corrosive product. They are constructed of smooth powder-coated steel or aluminum tubing, a capture hood with adjustment grips, flex hose joint covers, and external adjustment brackets for the hood and swivel joints. The assemblies come standard with a wall mounting bracket but also have ceiling and floor support brackets available. An internal damper is included for airflow adjustment or shutoff. The arm mounting brackets allow for 180⁰ and 360⁰ rotation. Arm diameter options range from three to ten inches, and arm lengths vary from three to thirty-two feet. The maximum airstream temperature for these arms is about 180 degrees Fahrenheit.

    Features and options:

    • Includes duct connection collar
    • An optional fume exhaust fan in aluminum, carbon steel, or PVC.
    • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', and 14'.
    • Grab handle around the hood that is aluminum powder-coated black.
    • Black hose rated for 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
    • The wall bracket is powder-coated black.
    • A shutoff damper is built into the lower tube.

    Economical Industrial Extraction Arms in Akhiok AK


    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:

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

    Akhiok, Alaska 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.

    • 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.
    • Shut off dampers built internally.
    • Low-pressure drop
    Akhiok, Alaska Fume Extraction Arm Optional Accessories

    Akhiok, Alaska Fume Extraction Arm Optional Accessories

    Fume extraction arms have optional accessories that include:

    Hood lights – Lights can be attached to the arm hood to provide better vision at the work point. Often used in welding applications.

    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.

    Custom hoods – To maximize fume capture, standard circular or scoop-shaped hoods can be changed to a slotted design, rectangular, flat, or custom fabricated.

    Wall Mount - A wall bracket designed to mount the arm to any wall or beam within the facility.

    Nozzles - To get even closer to source capture, suction nozzles and flexible suction nozzles are available.

    Floor Stanchion - When the ceiling is too high, or there are no walls, a floor stanchion can be used to mount the arm.

    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.

    Akhiok, Alaska Extraction Arm Selection and Performance

    Akhiok, Alaska Extraction Arm Selection and Performance

    The first step in extraction arm selection is determining how the arm will be used, the required work area, and any space constraints for hood positioning. The required arm length is determined by the arm mounting location and where the capture hood will be used. The selection of an extraction arm is based on several criteria:

    Performance – The volume of exhaust air required is in cubic feet per minute or CFM, and the resistance to airflow is in inches W.G. or static pressure (S.P.) Because the arms are moveable, the S.P. thru the arm will change with arm and hood positioning.

    The total S.P. requirement for an extraction arm is based on arm length, the number of arm elbows, the type of arm tubing, the type of hood, and internal or external support structure. Arm manufacturers include this value in their literature along with performance curves. The static pressure will change when the arm is repositioned (extended or compressed). Depending on the arm selected and the work area size, it could be a minor or significant change in fume capture. When choosing an arm, it is best to size the S.P. requirement as the worst case.

    The CFM requirement for source capture varies with the collected fume, dust, or product. The amount of collected air is based on the hood capture efficiency, the position of the hood to the fume source, and any crossflow air currents. Follow the project design specifications or contact SysTech for recommended CFM.

    Frequency of use – Infrequent usage or continual use dictates light or heavy-duty construction.

    Mounting Location - Where the arm is located will determine the arrangement of the design. We can provide them in bench, wall, or ceiling mount designs. These should be selected to access the captured waste stream by locating the arm as close as possible to the process.

    Applicable Codes – Typical requests include FDA compliance with food-grade materials or minimizing fire/explosion potential.

    Environment – Dirt or abrasive materials in the ambient room air may adversely affect the arm joints. Also considered is hood capture efficiency being compromised where crossflow air currents exist in the workspace.

    Airstream constituents – What is in the airstream will determine the materials of construction, most notably, explosion or fire hazards, abrasive materials, and aggressive chemicals. Materials can be aluminum, polypropylene, stainless steel, and in some cases, carbon steel.
