951762 - Miller FILTAIR SWX Dual-Arm Expansion Kit with 10ft ZoneFlow Arm

Expand Industrial Fume Control with ZoneFlow Technology

The Miller FILTAIR® SWX Dual-Arm Add-On Package (951762) is a specialized industrial ventilation solution designed to upgrade existing single-arm SWX stationary fume extraction systems into dual-arm configurations. This package is engineered for facilities requiring expanded coverage without the complete overhaul of their central filtration infrastructure. By integrating a second high-performance extraction point, facility managers can double the throughput of their welding stations or accommodate two operators simultaneously, maximizing the utility of the FILTAIR SWX system.

At the core of this package is Miller's proprietary ZoneFlow™ technology. Unlike standard extraction arms that rely solely on high-velocity suction at the hood face, ZoneFlow creates a large negative pressure zone that funnels air toward the center of the arm. This innovative aerodynamic design extends the effective capture distance up to five feet—significantly further than the 12-18 inches typical of conventional arms. For industrial hygienists and safety officers, this means a higher probability of capturing weld fumes at the source, reducing the ambient particulate load in the facility and ensuring stricter compliance with air quality standards.

The package includes a dedicated FEB-1 blower motor operating at 115V, ensuring that the addition of the second arm does not compromise the suction power of the existing setup. The system delivers a nominal airflow of 875 CFM at the hood, powered by a fan capable of generating 1,200 CFM. This ensures that even with the extended capture zone, the velocity remains sufficient to entrain metal oxide particulates effectively. The arm itself features external adjustments, removing obstructions from the airstream to minimize pressure drop and turbulence, which further enhances energy efficiency and acoustic performance (operating at approximately 80 dBA).

Installation is streamlined with the included mounting brackets, backdraft dampers, and flexible ducting. The ZoneFlow motor control box allows for precise management of the capture zone, offering operators the ability to switch between a 360-degree capture area and a 180-degree area for working against walls or curtains. This adaptability makes the SWX Dual-Arm Add-On a critical asset for dynamic manufacturing environments where part sizes and welding positions vary.
