951520 - Miller FILTAIR SWX Dual-Arm Expansion Kit, 10ft Standard Arm

Technical Overview of the Miller FILTAIR SWX Dual-Arm Add-On

The Miller FILTAIR SWX Dual-Arm Add-On Package (SKU: 951520) is a comprehensive expansion solution designed to convert an existing single-arm SWX fume extraction installation into a dual-arm system. This package is engineered to provide industrial-grade fume capture for welding environments requiring extended reach and high airflow. The core of the system is the FEB-1 blower motor, a 115V high-performance fan capable of generating 1,200 CFM of free air flow. When integrated with the included 10-foot standard extraction arm, the system delivers an Accu-Rated minimum of 875 CFM at the hood, ensuring compliance with rigorous air quality standards during heavy welding operations.

The 10-foot standard arm included in this package is constructed with external adjustments. Unlike internal mechanisms that obstruct airflow and create turbulence, the external design minimizes pressure drop, thereby maximizing suction efficiency at the capture point. The arm utilizes a durable bellmouth-shaped hood which significantly improves capture velocity and distance compared to traditional conical hoods. This design allows for effective fume containment even when the hood is positioned further from the arc, providing the operator with greater visibility and freedom of movement.

Installation of the add-on package integrates seamlessly with existing SWX infrastructure. The kit includes a dedicated mounting bracket, a 115V on/off control box, backdraft dampers to prevent reverse flow when the unit is inactive, and flexible ducting (7 x 37 inches) to connect the components. It is compatible with a wide range of welding processes, including Flux Cored (FCAW), MIG (GMAW), Stick (SMAW), and TIG (GTAW). Note that while the control hardware is included, 115V wiring must be supplied by the installer. This modular approach allows facility managers to customize their ventilation setup based on specific workstation geometries and airflow requirements.
