951761 - Miller FILTAIR SWX-S Self-Cleaning Fume Extractor with 12ft ZoneFlow Arm

Miller FILTAIR SWX-S Single-Arm Fume Extraction System

The Miller FILTAIR SWX-S (Self-Cleaning) package, SKU 951761, represents a pinnacle in industrial welding fume management. Designed for stationary wall or column mounting, this system integrates advanced airflow dynamics with superior filtration technology to ensure a safe working environment. The core of this package is the high-performance blower which generates 1,200 CFM of airflow, delivering an Accu-Rated minimum of 875 CFM at the hood. This powerful suction is critical for capturing weld fumes at the source before they enter the welder's breathing zone.

ZoneFlow™ Technology

This unit is equipped with a 12-foot ZoneFlow extraction arm. Unlike standard extraction arms that require close proximity (typically 12-18 inches) to the arc, ZoneFlow technology creates a large negative pressure zone that funnels air to the center of the arm from distances up to 5 feet away. This extended capture range is achieved by moving clean, filtered air out of the arm at approximately a 90-degree angle, creating a "curtain" of air that directs fumes into the capture hood. This significantly reduces the need for the operator to constantly reposition the arm, thereby increasing arc-on time and overall productivity.

FilTek® XL and Self-Cleaning Mechanism

The SWX-S model features a self-cleaning filter cabinet housing a FilTek XL filter. This filter utilizes nanofiber technology, which loads surface particulate rather than depth loading, allowing for easier cleaning and longer life. Rated at MERV 15, it captures up to 95% of weld fume particulate. The self-cleaning cycle is activated by a simple push-button control and takes only one minute. It employs a reverse pulse of compressed air to dislodge particulate from the filter, depositing it into an integrated disposal drawer for safe and easy removal. This mechanism ensures the system maintains high airflow efficiency over extended periods of use without frequent manual maintenance.

Installation and Control

The system runs on standard 115V single-phase power, making it accessible for most facility electrical grids. It includes all necessary control boxes for the blower, ZoneFlow motor, and cleaning cycle. The arm itself features external adjustments for reliable positioning and reduced airflow resistance, ensuring that the system operates at peak efficiency across its full range of motion.
