Akutan, Alaska Fume and Dust Extraction Arm Systems
Akutan 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.
Akutan, Alaska 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.
Akutan, Alaska 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.
- 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
- 304 SS grab handle on the hood for easy mobility and positioning.
- Optional fume exhaust fans in aluminum, carbon steel, or PVC.
- Clear anti-static FDA hose rated for 200 degrees Fahrenheit.
Exhaust Fans for Fume Extraction Arms in Akutan
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.
Akutan, Alaska Fume Extraction Arm Mounting and Supports
Fume extraction arms are continually moved, extended, and rotated, requiring them to be rigidly supported and mounted securely. A few factors affect mounting location: 1) the location of the fume source, 2) the coverage area for where the arm is used 3) the central system duct where the fume arm is connected.
Mounting options include:
Wall Mount - With duct systems running against a wall, mounting the arm (s) with brackets secured to a block wall or column is typical. If the central system duct is along the ceiling, on an outside wall, or mid-wall, there are designed brackets to fix the arm in place.
Bench Mount - Exhaust duct running along the floor allows mounting to a bench or tabletop. This mount has a standard option bracket for attaching the arm. Another standard bench mount is on a portable air filter or dust collector.
Ceiling Mount - Mounting the arms in the ceiling is an option if joists are present. A support weldment could be fabricated if a ceiling mount is a requirement. For low-weight short arms, the installation contractor can fabricate a wood fixture.
Stanchion Mount - When arms are located in the center of a facility having high bay areas, a stanchion will allow the mounting of an arm and hold it rigidly in place.
Akutan Telescopic Fume Extraction Arm
Telescopic extraction arms are designed to fit into confined spaces. They are used for those applications when the operator wants to "compress" the arm out of the way and pull it back to a working position. The unit will mount on the ceiling, wall, or floor stanchion. There are optional designs from which to choose. There is an arm with a ridged flex hose in six or eight-inch diameter having an operating range of seven feet to almost ten feet or a thin-walled tube design that is available in five-inch diameter and can telescope three feet out to seven feet. Both telescopic arm options would include a manual damper.
- Powder coated steel wall bracket is standard
- Optional fume exhaust fans in aluminum, carbon steel, or PVC.
- Swivel base
- The hood is powder-coated aluminum and includes a grab handle and shutoff damper built within
- Internal is telescopic
- Black hose rated up to 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
- Arm diameters are 6" and 8", and the operating range (compression) is 4' to 7'.
Akutan, Alaska 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.
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.
Hood lights – Lights can be attached to the arm hood to provide better vision at the work point. Often used in welding applications.
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.
Floor Stanchion - When the ceiling is too high, or there are no walls, a floor stanchion can be used to mount the arm.
Akutan, Alaska Downdraft Tables, Benches, and Walk-In Enclosures
Dust and fume generating work areas within a facility can often be controlled with self-contained and moveable downdraft tables. Tables can be designed for tabletop downdraft only or combined with a backdraft airflow design for nuisance dust capture. Particulate micron size and the amount of collected particulate, smoke, or fume determines the air filtration systems selected, with typical options including throw-away filters, pulse-clean dust collectors, or wet collectors. For some applications, a downdraft bench that incorporates downdraft and backdraft exhaust can be designed for repetitive work processes.
Adding an enclosure around the dust source and containing the generated dust or fume in a walk-in booth minimizes the amount of air that needs to be cleaned. Dust control enclosures encapsulate processes where particulate, smoke, or fume are difficult to contain and are transported and dispersed within a room by cross drafts, mancoolers, compressed air clean-offs, or processing equipment like sanders and grinders.
