951508 - Miller FILTAIR MWX-D Mobile Fume Extractor with 10ft Arm

Technical Overview of the Miller FILTAIR MWX-D

The Miller FILTAIR MWX-D (SKU: 951508) is a mobile fume extraction solution engineered for industrial environments requiring source capture of welding particulates. This unit is distinguished by its utilization of FilTek™ XL Filter Technology, a nanofiber-based media that offers significantly higher efficiency and longevity compared to traditional treated cellulose filters. The filter achieves a MERV 15 rating, capable of capturing up to 95% of weld fume particulates, including sub-micron sizes often generated during MIG and TIG processes.

Mechanically, the system is driven by a powerful motor delivering 875 CFM of airflow. The extraction path is optimized through the use of an externally adjustable 10-foot arm. By placing support components outside the airstream, Miller reduces pressure drop and turbulence, ensuring consistent suction at the hood. The hood itself utilizes a bellmouth design with 360-degree rotation, maximizing the capture velocity zone and reducing the frequency of repositioning required by the operator.

The MWX-D model is specifically designed with a disposable filter architecture, making it ideal for fabrication shops where ease of maintenance is a priority. A front-mounted filter pressure gauge provides immediate visual feedback on filter saturation, indicating precisely when the tool-free replacement is necessary. The unit operates on standard 115V single-phase power, drawing current compatible with standard shop outlets, and is housed in a durable industrial-grade metal cabinet mounted on heavy-duty casters for maneuverability.
