Acton, California 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.

Acton, California Fume Extraction Arm Optional Accessories

Acton, California 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.

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.

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

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

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.

Acton, California Fume Extraction Arm Mounting and Supports

Acton, California 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.

Acton 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.

  • Model having a semi-transparent white P.U. hose for dust-related pollutants.
  • Flexible PE hose, fully grounded.
  • They are manufactured following ATEX directive 2014/34/E.U. Category 2 for gases and dust.
  • Models having black chemical resistance P.E. hose
  • 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'.

Acton, California Stainless Steel Extraction Arms

Acton, California 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.
  • 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.
  • Available in hanging and benchtop models.
  • Clear anti-static FDA hose rated for 200 degrees Fahrenheit.
  • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', and 14'.
