951510 - Miller FILTAIR MWX-S Self-Cleaning Mobile Fume Extractor with 7ft Arm

Miller FILTAIR MWX-S Mobile Fume Extraction System (951510)

The Miller FILTAIR MWX-S (951510) is a premier mobile fume extraction solution designed specifically for industrial manufacturing environments where welding intensity is high and mobility is essential. This system distinguishes itself with Miller's proprietary FilTek XL filter technology, which is engineered to outperform and outlast traditional filtration media. The unit comes pre-assembled with a 7-foot extraction arm, offering immediate deployment capabilities for fabrication shops, training centers, and repair facilities.

At the core of the MWX-S is its MERV 15 rated filter, which provides superior filtration efficiency, capturing up to 95% of weld fume particulates. This is critical for compliance with safety standards regarding hazardous fumes such as hexavalent chromium. The FilTek XL technology utilizes surface-loading nanofibers rather than depth-loading cellulose. This architectural difference means that particles are trapped on the surface of the filter media, preventing them from embedding deep within the filter where they restrict airflow and are difficult to remove. Consequently, the MWX-S maintains a powerful 875 CFM airflow for longer durations, ensuring consistent protection for operators.

The "S" in MWX-S stands for Self-Cleaning, a feature that dramatically reduces operational costs and downtime. The unit incorporates a cleaning mechanism that uses a pulse of compressed air to dislodge particulate from the filter surface, depositing it into a secure storage drawer for easy disposal. This one-minute cleaning cycle can be activated by the operator whenever the front-panel pressure gauge indicates a pressure drop, effectively restoring airflow and extending the useful life of the filter cartridge. This system is far superior to disposable models for heavy-use applications, as it negates the need for frequent, costly filter replacements.

Mechanically, the unit is powered by a 1 HP motor running on standard 115V single-phase power, making it compatible with standard shop outlets. The 7-foot extraction arm is designed with external support structures, leaving the interior smooth to minimize turbulence and pressure loss. The large bellmouth hood offers a 360-degree rotation and superior capture velocity, allowing it to be effective even when positioned further from the arc than competitive models. With a robust steel chassis, heavy-duty casters, and a sound level of approximately 70 dBA, the MWX-S is an industrial-grade tool built to improve air quality without disrupting the work environment.
