Economical Industrial Extraction Arms in Tunnel Hill GA


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

Tunnel Hill 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
  • They are manufactured following ATEX directive 2014/34/E.U. Category 2 for gases and dust.
  • Model having a semi-transparent white P.U. hose for dust-related pollutants.
  • Flexible PE hose, fully grounded.
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Arm diameters include 4", 5", 6", and 8", and arm lengths include 5', 7', 10', 13', 16', and 23'.

Tunnel Hill GA Fume Extraction Arms

Industrial exhaust systems for capturing smoke, fume, dust, high-temperature air, and corrosive gases.

Tunnel Hill, Georgia Fume Extraction Arm Optional Accessories

Tunnel Hill, Georgia Fume Extraction Arm Optional Accessories

Fume extraction arms have optional accessories that include:

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.

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.

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.

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

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

Tunnel Hill 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. Tunnel Hill, Georgia Laboratory bench mount arms are an option and are available in three and four-inch diameter tubes up to six feet in length.

  • Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.
  • Market-leading low-pressure drop
  • 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.
  • 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.

Tunnel Hill, Georgia Extraction Arm Selection and Performance

Tunnel Hill, Georgia 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.

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.

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

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.

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

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.
