951512 - Miller Filtair MWX-S Mobile Fume Extractor, 12ft Arm, Self-Cleaning

Advanced Mobile Fume Extraction for Industrial Environments

The Miller Filtair MWX-S (951512) is a high-performance mobile fume extraction system engineered for heavy-duty industrial welding applications. This unit distinguishes itself with Miller's proprietary FilTek XL filter technology and a built-in self-cleaning mechanism, designed to maximize uptime and reduce long-term operating costs. The system delivers a powerful 875 CFM of airflow, ensuring effective capture of weld fumes at the source, which is critical for maintaining compliance with OSHA standards and protecting facility air quality.

At the core of the MWX-S is the FilTek XL filter, which utilizes surface-loading nanofiber technology. Unlike traditional cellulose filters that trap particles deep within the media, nanofibers capture particulates on the surface. This design allows the unit's self-cleaning cycle to be highly effective. By simply pushing a button, a one-minute pulse cleaning cycle initiates, using reverse air flow to dislodge particulate from the filter and deposit it into a collection drawer. This process extends filter life up to two times that of standard filters, significantly reducing replacement frequency and maintenance downtime.

The unit is equipped with a 12-foot extraction arm, providing an extensive reach for large weldments or work cells where positioning flexibility is required. The arm features external adjustments to minimize airflow resistance and a durable bellmouth hood that rotates 360 degrees for optimal positioning. The cabinet is constructed from heavy-duty steel to withstand harsh shop environments and is mounted on large rear wheels and lockable front casters for easy mobility over cables and uneven floors. With a MERV 15 rating, this system effectively filters 95% of weld fume particulates, making it an essential asset for fabrication shops prioritizing efficiency and air quality.
