Rockville, Alabama 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.

Rockville, Alabama Fume Extraction Arm Mounting and Supports

Rockville, Alabama 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.

Rockville 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.

  • 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'.
  • Powder coated steel wall bracket is standard
  • The hood is powder-coated aluminum and includes a grab handle and shutoff damper built within
  • Internal is telescopic
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Swivel base

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

General Purpose Rockville, Alabama Industrial Extraction Arm

"General Purpose" Rockville, Alabama 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:

  • An optional fume exhaust fan 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'.
  • Includes duct connection collar
  • Grab handle around the hood that is aluminum powder-coated black.
  • A shutoff damper is built into the lower tube.
  • Black hose rated for 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
  • The wall bracket is powder-coated black.
Rockville, Alabama Fume Extraction Arm Optional Accessories

Rockville, Alabama Fume Extraction Arm Optional Accessories

Fume extraction arms have optional accessories that include:

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.

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.

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.
