General Purpose Bancroft, Idaho Industrial Extraction Arm

"General Purpose" Bancroft, Idaho 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:

  • The wall bracket is powder-coated black.
  • Includes duct connection collar
  • 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'.
  • Black hose rated for 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
  • Grab handle around the hood that is aluminum powder-coated black.
  • A shutoff damper is built into the lower tube.

Bancroft, Idaho 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.

Bancroft, Idaho Weld Fume Extraction Arm

Bancroft, Idaho Weld Fume Extraction Arm

The demand for weld smoke extraction arms is always high and mandates an arm category. Depending on the application, different designs use either smooth wall or flex hose tubing. Both designs use external positioning joints and a hood with an internal adjustable damper. The units are typically wall-mounted but have ceiling and floor support bracket options. Arm diameter options range from six to eight inches, and arm lengths vary from three feet up to thirty-six feet. Personal weld fume packages include a single extraction arm, exhaust fan, and air filter.

  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Standard units include a wall bracket. Ceiling mount options are available.
  • Low-pressure drop
  • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', 14', 16', 23', 30', and 36'.
  • Shut off dampers built internally.

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

  • 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.
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Market-leading low-pressure drop
  • Arm diameters include 2", 3", and 4", and arm lengths include 25", 30", 39", 45",51", 53", 59", 65", 75", 79", 83", and 104".
  • Wall brackets, ceiling brackets, and table mount brackets are available.

Bancroft, Idaho 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.

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