Fume and Dust Extraction Arm Systems in Frederick County

Frederick County Fume 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.

Frederick County 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.

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.

Frederick County 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.

Frederick County Extraction Arm Selection and Performance

Frederick County Extraction Arm Selection and Performance

The first step in extraction arm selection is determining how the arm will be used, the required work area, and any space constraints for hood positioning. The required arm length is determined by the arm mounting location and where the capture hood will be used. The selection of an extraction arm is based on several criteria:

Performance – The volume of exhaust air required is in cubic feet per minute or CFM, and the resistance to airflow is in inches W.G. or static pressure (S.P.) Because the arms are moveable, the S.P. thru the arm will change with arm and hood positioning.

The total S.P. requirement for an extraction arm is based on arm length, the number of arm elbows, the type of arm tubing, the type of hood, and internal or external support structure. Arm manufacturers include this value in their literature along with performance curves. The static pressure will change when the arm is repositioned (extended or compressed). Depending on the arm selected and the work area size, it could be a minor or significant change in fume capture. When choosing an arm, it is best to size the S.P. requirement as the worst case.

The CFM requirement for source capture varies with the collected fume, dust, or product. The amount of collected air is based on the hood capture efficiency, the position of the hood to the fume source, and any crossflow air currents. Follow the project design specifications or contact SysTech for recommended CFM.

Applicable Codes – Typical requests include FDA compliance with food-grade materials or minimizing fire/explosion potential.

Environment – Dirt or abrasive materials in the ambient room air may adversely affect the arm joints. Also considered is hood capture efficiency being compromised where crossflow air currents exist in the workspace.

Mounting Location - Where the arm is located will determine the arrangement of the design. We can provide them in bench, wall, or ceiling mount designs. These should be selected to access the captured waste stream by locating the arm as close as possible to the process.

Frequency of use – Infrequent usage or continual use dictates light or heavy-duty construction.

Airstream constituents – What is in the airstream will determine the materials of construction, most notably, explosion or fire hazards, abrasive materials, and aggressive chemicals. Materials can be aluminum, polypropylene, stainless steel, and in some cases, carbon steel.

Exhaust Fans for Fume Extraction Arms in Frederick County

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.
