Twin Hills 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.

  • Arm diameters include 4", 5", 6", and 8", and arm lengths include 5', 7', 10', 13', 16', and 23'.
  • 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.
  • Model having a semi-transparent white P.U. hose for dust-related pollutants.

Twin Hills, 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.

  • 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'.
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Available in hanging and benchtop models.
  • 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
  • Clear anti-static FDA hose rated for 200 degrees Fahrenheit.

Twin Hills AK Fume Extraction Arms

Industrial exhaust systems for capturing smoke, fume, dust, high-temperature air, and corrosive gases.

General Purpose Twin Hills, Alaska Industrial Extraction Arm

"General Purpose" Twin Hills, Alaska 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.
  • 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'.
  • Grab handle around the hood that is aluminum powder-coated black.
  • Includes duct connection collar
  • Black hose rated for 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
  • An optional fume exhaust fan in aluminum, carbon steel, or PVC.

Economical Industrial Extraction Arms in Twin Hills AK


These extraction arms serve a similar function as the general-purpose extraction arm but are constructed with a flexible hose instead of metal tubing. This arm has cost savings, but some optional features are unavailable. These arms were designed for light-duty, intermittent applications and have limitations on some airstream constituents. Importantly, each application is reviewed upfront by SysTech will guide you through the selection process safely. Hose diameter alternatives range from four to eight inches, and arm lengths range from five to thirty-six feet. The standard hose material is blue PVC or white PVC with an option for PE-coated polyamide fabric for mild corrosive applications. Custom sizes can be designed using various parts for different arm models combined to make a new arm design.

Features and options:

  • High positional stability
  • Arm diameters include 4", 5", 6", and 8", and arm lengths include 5', 7', 10', 13', 16', 23', 30', and 36'.
  • Unique ease of maneuverability
  • Lightweight construction balanced by two gas springs.
  • Hood designed for maximum capture efficiency and extraction
  • Lowest possible pressure drop, which helps save energy and lowers sound levels
  • External arm support
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.

New and Retrofitted Extraction Arm Systems in Twin Hills

When you install a new fume extraction arm or arms, it improves air cleaning system performance, resulting in a cleaner work environment. Expectations can be met if all-important selection factors are considered and limitations for capture are pointed out.

If you are repairing, replacing, or adding a new arm or arms, to an existing system, the critical components of the fume exhaust system should be reviewed, including the duct system, the exhaust fan (s), and the air cleaning device. Systems are only as efficient as their individual parts, and SysTech will review your components with you to evaluate if your system is operating at peak performance.
