The Miller 300982 Standard Extraction Arm (Model SA-W812-WM) is a high-performance component designed for the rigorous demands of industrial fume capture. Engineered with an 8-inch diameter, this arm is specifically sized to handle significant volumes of air, ensuring that weld fumes are effectively evacuated from the source before they can disperse into the facility. The 12-foot length provides an expansive operational envelope, allowing the arm to cover a substantial work area. This extended reach is critical for applications involving large weldments or fixtures where repositioning the base extraction unit is impractical or inefficient.
A key engineering feature of the SA-W812-WM is its external adjustment mechanism. Unlike traditional extraction arms that house support springs and friction joints inside the ductwork, Miller has moved these components to the exterior. This design choice eliminates internal obstructions that typically cause turbulence and static pressure drop. The result is a smoother, more laminar airflow path that maximizes the cubic feet per minute (CFM) performance of the connected blower system. By reducing airflow resistance, the system operates more efficiently, potentially reducing energy consumption and wear on the extraction motor.
The arm is preassembled for immediate deployment, reducing installation time and labor costs. It terminates in a durable, bellmouth-shaped hood designed to optimize capture velocity. The hood features a 360-degree rotation capability, granting operators unlimited positioning options to align the capture zone with the weld pool effectively. The FILTAIR extraction hood design is calibrated to capture fumes at a greater distance than standard hoods, which translates to fewer adjustments during long weld passes. This unit is a wall-mount configuration, making it an ideal permanent fixture for welding booths and fabrication stations requiring reliable, fixed-point source capture.
