Chimney Hill 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.

  • 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'.
  • 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.
  • Models having black chemical resistance P.E. hose

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

  • Wall brackets, ceiling brackets, and table mount brackets are available.
  • Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.
  • Various hood options for more efficient source capture include dome hoods, square hoods, flat screen hoods, metal hoods, and suction nozzles.
  • Market-leading low-pressure drop
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Arm diameters include 2", 3", and 4", and arm lengths include 25", 30", 39", 45",51", 53", 59", 65", 75", 79", 83", and 104".

Economical Industrial Extraction Arms in Chimney Hill VT


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:

  • Lowest possible pressure drop, which helps save energy and lowers sound levels
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Lightweight construction balanced by two gas springs.
  • External arm support
  • 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
  • Hood designed for maximum capture efficiency and extraction

Chimney Hill 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.

  • Arm diameters are 6" and 8", and the operating range (compression) is 4' to 7'.
  • The hood is powder-coated aluminum and includes a grab handle and shutoff damper built within
  • Swivel base
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Black hose rated up to 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
  • Powder coated steel wall bracket is standard
  • Internal is telescopic

Chimney Hill, Vermont 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.

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