Fume and Dust Extraction Arm Systems in Snohomish County

Snohomish County Fume 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.

Snohomish County 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.

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.

Snohomish County 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. Snohomish County Laboratory bench mount arms are an option and are available in three and four-inch diameter tubes up to six feet in length.

• Market-leading low-pressure drop
• Various hood options for more efficient source capture include dome hoods, square hoods, flat screen hoods, metal hoods, and suction nozzles.
• Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.
• Wall brackets, ceiling brackets, and table mount brackets are available.
• Optional fume exhaust fans in aluminum, carbon steel, or PVC.
• Arm diameters include 2", 3", and 4", and arm lengths include 25", 30", 39", 45",51", 53", 59", 65", 75", 79", 83", and 104".

Snohomish County 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.

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

"General Purpose" Snohomish County 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:

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

Snohomish County 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.

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

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.

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.

Snohomish County 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.

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