Miller SA-810 8-Inch x 10-Foot Fume Extraction Arm

Miller 300978 FILTAIR SA-810: Industrial Grade Fume Capture

The Miller 300978 FILTAIR SA-810 Fume Extraction Arm represents the gold standard in localized fume control accessories. Designed as a direct component for the Miller FILTAIR MWX series (specifically the MWX-S and MWX-D mobile extractors), this arm is engineered to deliver reliable performance in demanding fabrication environments. Welding fumes pose significant health risks, and capturing them at the source is the most effective method of mitigation. The SA-810 facilitates this with a design that prioritizes airflow, reach, and ease of use.

Optimized Airflow and Reach

At the core of the SA-810's performance is its 8-inch (203 mm) diameter tube. Unlike smaller diameter arms that can restrict airflow and reduce capture velocity, the 8-inch design allows for a higher volume of air to be moved with less resistance. This is essential for capturing thermal plumes generated during high-amperage welding. Complementing this flow capacity is the arm's impressive 10-foot (3 meter) reach. This extended length gives welders the freedom to work around large assemblies or fixtures without being tethered closely to the filtration unit. The arm can be extended, retracted, and rotated to position the capture hood exactly where it is most effective.

Durability and User-Centric Design

Miller has constructed the SA-810 to endure the harsh conditions typical of welding shops. The external adjustments and support mechanisms are designed for longevity and ease of maintenance. One of the standout features for maintenance teams is that the arm arrives pre-assembled. This eliminates the complex puzzle of assembling tension springs and friction joints, allowing for immediate deployment upon delivery. The arm's articulation is smooth and balanced, ensuring that once the hood is positioned, it remains stable without drifting, which is a common complaint with inferior extraction arms.

Seamless Integration

This arm is not a universal fit-all solution but a specialized component for the FILTAIR MWX line. This specific compatibility ensures that the connection points, airflow dynamics, and balance are perfectly tuned for the MWX-S and MWX-D units. Using genuine Miller parts like the SA-810 guarantees that your safety equipment operates as intended, maintaining compliance with safety regulations and protecting your most valuable asset—your workforce.
