951507 - Miller FILTAIR MWX-D Mobile Fume Extractor with 7ft Arm

Miller FILTAIR MWX-D Mobile Fume Extraction System

The Miller FILTAIR MWX-D (Disposable Filter Model) is a high-performance mobile fume extraction system designed specifically for welding applications. Engineered with industrial-grade components, this unit provides a robust solution for source capture in fabrication shops, manufacturing plants, and training facilities. The system is built around a powerful 1 HP motor that delivers a nominal airflow of 875 CFM (413 L/sec), ensuring effective removal of hazardous particulates from the welder's breathing zone.

At the core of the MWX-D is Miller's proprietary FilTek XL filter technology. Unlike traditional treated cellulose filters that rely on depth loading, FilTek XL utilizes a surface-loading nanofiber media. This design allows for a MERV 15 rating, capable of capturing up to 95% of weld fume particulates as small as 0.3 to 1.0 microns. The surface-loading characteristic also contributes to a longer filter life and lower operating resistance. The MWX-D model is specifically configured with a disposable filter cartridge, making it an ideal choice for environments with light to medium arc times where self-cleaning mechanisms are not required.

The 951507 package includes a pre-assembled 7-foot extraction arm. This arm is constructed with external adjustments and supports, removing obstructions from the internal airstream. This design minimizes pressure drop and turbulence, maximizing the system's suction power at the hood. The bellmouth-shaped extraction hood is one of the largest in the industry and features 360-degree rotation, allowing operators to position the capture zone precisely where needed without constant readjustment. The hood's design enables effective fume capture at greater distances than standard conical hoods.

Operational maintenance is simplified through a front-panel filter pressure gauge. This easy-to-read indicator uses color-coded zones to alert maintenance personnel when the pressure drop across the filter has reached the threshold for replacement. The unit is housed in a durable metal cabinet designed to withstand the rigors of industrial environments. Mobility is provided by large rear wheels for traversing cables and uneven floors, while lockable front swivel casters ensure stability during operation. The system runs on standard 115 VAC, single-phase power, drawing approximately 11.9 Amps, making it compatible with standard shop outlets.
