Annandale, New Jersey Fume and Dust Extraction Arm Systems

Annandale Industrial exhaust systems are designed to capture smoke, fume, dust, high-temperature air, and corrosive gases. These "pollutants" are ducted to an air cleaner (purification system) before discharge to the outside or returned to the workspace. Capturing air-entrained materials is best accomplished at the emission source, defined as source capture.

Multiple arm designs are available depending on the airstream constituents. The parameters evaluated are temperature, explosivity, corrosiveness, and particulate, all factors determining the type of arm that should be selected for a process application. Matching your expected exhaust volume and arm useage with the required exhaust CFM, pressure loses, and airstream being captured is what we do. SysTech has successfully applied extraction arms for over thirty years and will assist with the correct selection for your process.

Annandale, New Jersey Fume extraction arms with hoods or suction nozzles are the number one tool to maximize source capture efficiency. They capture the contaminated airstreams while getting close to the source without disrupting or slowing down the work process or collecting too much useable product. When the task or workpiece is difficult to access, in an isolated area, or along awkward points on an assembly line, extraction arms are a proven solution for maximum particulate, smoke, and fume collection.

Annandale, New Jersey 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.

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.

New and Retrofitted Extraction Arm Systems in Annandale

When you install a new fume extraction arm or arms, it improves air cleaning system performance, resulting in a cleaner work environment. Expectations can be met if all-important selection factors are considered and limitations for capture are pointed out.

If you are repairing, replacing, or adding a new arm or arms, to an existing system, the critical components of the fume exhaust system should be reviewed, including the duct system, the exhaust fan (s), and the air cleaning device. Systems are only as efficient as their individual parts, and SysTech will review your components with you to evaluate if your system is operating at peak performance.

Annandale 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. Annandale, New Jersey 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".
• Various hood options for more efficient source capture include dome hoods, square hoods, flat screen hoods, metal hoods, and suction nozzles.
• Market-leading low-pressure drop
• Optional fume exhaust fans in aluminum, carbon steel, or PVC.
• Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.
• Wall brackets, ceiling brackets, and table mount brackets are available.

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

Annandale, New Jersey Fume Extraction Arm Optional Accessories

Fume extraction arms have optional accessories that include:

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

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

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.

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

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

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.
