Maryland Fume and Dust Extraction Arm Systems

Maryland Industrial exhaust systems are designed to capture smoke, fume, dust, high-temperature air, and corrosive gases. These "pollutants" are ducted to an air cleaner (purification system) before discharge to the outside or returned to the workspace. Capturing air-entrained materials is best accomplished at the emission source, defined as source capture.

Multiple arm designs are available depending on the airstream constituents. The parameters evaluated are temperature, explosivity, corrosiveness, and particulate, all factors determining the type of arm that should be selected for a process application. Matching your expected exhaust volume and arm useage with the required exhaust CFM, pressure loses, and airstream being captured is what we do. SysTech has successfully applied extraction arms for over thirty years and will assist with the correct selection for your process.

Maryland Fume extraction arms with hoods or suction nozzles are the number one tool to maximize source capture efficiency. They capture the contaminated airstreams while getting close to the source without disrupting or slowing down the work process or collecting too much useable product. When the task or workpiece is difficult to access, in an isolated area, or along awkward points on an assembly line, extraction arms are a proven solution for maximum particulate, smoke, and fume collection.

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

Exhaust Fans for Fume Extraction Arms in Maryland

Industrial exhaust system arms often need a connection to an exhaust fan for isolated applications or when needed for additional static resistance when connecting to an existing duct system. Fan CFM and static pressure must be examined in both cases to maintain system performance. When coupling with an exhaust fan, it should be constructed of similar or compatible materials to the extraction arm.

Cast Aluminum Pressure Blowers

Cast aluminum pressure blowers are typically supplied by manufacturers where there is a non-corrosive airstream. They are light, come in a wide range of designs, are compact, and are AMCA B spark-resistant as standard. Motors are available in single and three-phase TEFC and EXP frames.

Carbon Steel Blowers

If conditions of the airstream are suitable, a carbon steel painted fan is selected in a direct drive arrangement with a horizontal mount configuration that requires minimal space. Steel blowers have the option for AMCA construction up to AMCA A and 304 and 316 SS construction. Motors are available in single and three-phase TEFC and EXP frames.

Industrial Plastic Fume Exhaust Fans

Corrosive environments require materials of construction that will not degrade over time. Plastic construction is misunderstood as fragile, but industrial-grade designs are compatible with the harshest environment. The plastics typically used for construction are PVC or polypropylene (P.P.) and are an excellent choice for the efficient conveyance of corrosive, chemically laden, humid, or polluted gases, fumes, and air. Motors are available in single and three-phase TEFC and EXP frames.

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

• Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.
• 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".
• Wall brackets, ceiling brackets, and table mount brackets are available.
• Market-leading low-pressure drop
• Various hood options for more efficient source capture include dome hoods, square hoods, flat screen hoods, metal hoods, and suction nozzles.

Maryland 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.

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

Maryland Fume Extraction Arm Optional Accessories

Fume extraction arms have optional accessories that include:

Hood lights – Lights can be attached to the arm hood to provide better vision at the work point. Often used in welding applications.

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

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.

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

Nozzles - To get even closer to source capture, suction nozzles and flexible suction nozzles are available.

Custom hoods – To maximize fume capture, standard circular or scoop-shaped hoods can be changed to a slotted design, rectangular, flat, or custom fabricated.

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.
