Exhaust Fans for Fume Extraction Arms in Barnum

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.

Fume Extraction Arm Exhaust Fans in Barnum
General Purpose Barnum, Iowa Industrial Extraction Arm

"General Purpose" Barnum, Iowa 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:

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

Economical Industrial Extraction Arms in Barnum IA


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:

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

    Barnum, Iowa Fume Extraction Arm Optional Accessories

    Barnum, Iowa 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.

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

    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.

    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.

    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.

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

    Barnum 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. Barnum, Iowa 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".
    • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
