951520 - Miller FILTAIR SWX Dual-Arm Conversion Kit 10ft Standard Arm

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

The Miller FILTAIR SWX Dual-Arm Add-On Package (951520) is an industrial-grade expansion kit designed to convert single-arm SWX fume extraction installations into dual-arm systems. This package is engineered for heavy-duty welding environments, providing a second dedicated extraction point without the need for a completely separate system footprint. The core of this package is the high-performance FEB-1 blower motor, which operates on 115 V input power and generates a free-air flow of 1,200 CFM. When coupled 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.

The 10-foot standard arm included in this package is constructed with a focus on airflow efficiency and durability. Unlike arms with internal support mechanisms that create turbulence and collect particulate buildup, this Miller arm features external adjustments. This design allows air to pass through the 8-inch diameter tube with minimal resistance, maintaining consistent suction power. The arm is terminated with a durable bellmouth-shaped hood, which is one of the largest in the industry. The hood features 360-degree rotation, allowing for unlimited positioning options to capture fumes effectively from various angles.

Installation of the add-on package integrates seamlessly with existing SWX mounting configurations. The kit includes a mounting bracket specifically designed for the blower and arm, a 7 x 37-inch flexible duct for connection, and backdraft dampers to prevent reverse airflow when the unit is inactive. A 115 V on/off control box is provided for localized operation. It is important to note that while the control box and blower are included, the 115 V wiring itself is not supplied and must be installed according to local electrical codes. This system is rated for use with Flux Cored (FCAW), MIG (GMAW), Stick (SMAW), and TIG (GTAW) welding processes.
