Exhaust Fans for Fume Extraction Arms in Ahwahnee

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 Fume Exhauster

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.

    Ahwahnee, California Extraction Arm Selection and Performance

    Ahwahnee, California 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.

    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.

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

    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.

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

    General Purpose Ahwahnee, California Industrial Extraction Arm

    "General Purpose" Ahwahnee, California 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.
    • Black hose rated for 195 degrees Fahrenheit (intermittent 260 degrees Fahrenheit)
    • Includes duct connection collar
    • Grab handle around the hood that is aluminum powder-coated black.
    • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', and 14'.
    • The wall bracket is powder-coated black.
    • An optional fume exhaust fan in aluminum, carbon steel, or PVC.

    Ahwahnee 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.
    • Internal is telescopic
    • 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
    • Powder coated steel wall bracket is standard
    • Swivel base

    Economical Industrial Extraction Arms in Ahwahnee CA


    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.
