Atqasuk, Alaska Extraction Arm Selection and Performance

Atqasuk, 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.

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.

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

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.

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.

Atqasuk, Alaska Stainless Steel Extraction Arms

Aggressive airstream chemistry may require the arms to be constructed of 304 stainless steel. The tubing and hood are stainless, with external adjustment joints at the hood and swivel joints. Arm assemblies have a wall mounting bracket and an internal damper for airflow adjustment and shutoff. The standard flex hose at the joints is an FDA Pur Antistatic hose. Stainless steel arm tube diameters vary from three to eight inches, and arm lengths from three feet up to fourteen feet, all suitable for washdown applications. 316 stainless steel construction is an available option.

  • Optional fume exhaust fans 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'.
  • 304 SS grab handle on the hood for easy mobility and positioning.
  • External joints are anodized aluminum.
  • Clear anti-static FDA hose rated for 200 degrees Fahrenheit.
  • Tubes, hood, internal shutoff damper, and duct connection collar are all constructed of 304SS
  • Available in hanging and benchtop models.

Atqasuk 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.

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

    Atqasuk, 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.

    • 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.
    • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
    • Standard units include a wall bracket. Ceiling mount options are available.
    • Low-pressure drop
