Alden, Iowa Stainless Steel Extraction Arms

Alden, Iowa 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.
  • 304 SS grab handle on the hood for easy mobility and positioning.
  • Clear anti-static FDA hose rated for 200 degrees Fahrenheit.
  • Available in hanging and benchtop models.
  • External joints are anodized aluminum.
  • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', and 14'.
  • Tubes, hood, internal shutoff damper, and duct connection collar are all constructed of 304SS

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

    Exhaust Fans for Fume Extraction Arms in Alden

    Industrial exhaust system arms often need a connection to an exhaust fan for isolated applications or when needed for additional static resistance when connecting to an existing duct system. Fan CFM and static pressure must be examined in both cases to maintain system performance. When coupling with an exhaust fan, it should be constructed of similar or compatible materials to the extraction arm.

    Cast Aluminum Pressure Blowers

    Cast aluminum pressure blowers are typically supplied by manufacturers where there is a non-corrosive airstream. They are light, come in a wide range of designs, are compact, and are AMCA B spark-resistant as standard. Motors are available in single and three-phase TEFC and EXP frames.

    Carbon Steel Fume Exhauster

    If conditions of the airstream are suitable, a carbon steel painted fan is selected in a direct drive arrangement with a horizontal mount configuration that requires minimal space. Steel blowers have the option for AMCA construction up to AMCA A and 304 and 316 SS construction. Motors are available in single and three-phase TEFC and EXP frames.

    Industrial Plastic Fume Exhaust Fans

    Corrosive environments require materials of construction that will not degrade over time. Plastic construction is misunderstood as fragile, but industrial-grade designs are compatible with the harshest environment. The plastics typically used for construction are PVC or polypropylene (P.P.) and are an excellent choice for the efficient conveyance of corrosive, chemically laden, humid, or polluted gases, fumes, and air. Motors are available in single and three-phase TEFC and EXP frames.

    Alden, Iowa Extraction Arm Selection and Performance

    Alden, Iowa 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.

    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.

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

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

    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.

    Alden ATEX Rated Fume Extraction Arms

    Explosion-rated extraction arms are available for the handling of explosive gases and dust. (The combustible materials need to be identified upfront to determine the arm selection and hose material, if there is particulate, is corrosive.) These extraction arms meet the requirements of the ATEX Directive 2014/34/E.U. Category 2 for gases and dust for Zones 1 and 21 (areas where an explosive atmosphere is likely to occur during regular operation). ATEX-rated fume arm tube diameters vary from four to eight inches, and arm lengths are optional from five feet up to twenty-three feet.

    • Models having black chemical resistance P.E. hose
    • Flexible PE hose, fully grounded.
    • Model having a semi-transparent white P.U. hose for dust-related pollutants.
    • They are manufactured following ATEX directive 2014/34/E.U. Category 2 for gases and dust.
