951511 - Miller FILTAIR MWX-S Mobile Fume Extractor with 10ft Arm

Industrial-Grade Mobile Fume Extraction

The Miller FILTAIR MWX-S (951511) is a premier mobile fume extraction solution designed specifically for the rigors of industrial welding environments. This package includes the high-performance MWX-S base unit coupled with a pre-assembled 10-foot extraction arm, offering a versatile reach for diverse fabrication setups. At the core of this system is Miller's proprietary FilTek XL filter technology. Unlike traditional depth-loading filters that trap particles inside the media, FilTek XL utilizes a surface-loading nanofiber web. This design allows the filter to capture 95% of weld fume particulates—meriting a MERV 15 rating—while remaining easily cleanable.

The defining feature of the MWX-S model is its integrated self-cleaning mechanism. By connecting the unit to a standard dry compressed air supply, operators can initiate a one-minute pulse cleaning cycle. This mechanism releases a burst of reverse airflow that dislodges particulate from the filter surface, depositing it into a collection drawer for safe disposal. This system extends filter life up to twice that of treated cellulose filters, ensuring consistent airflow of 875 CFM and reducing long-term consumable costs.

Engineered for operational efficiency, the unit is powered by a 1 HP motor running on standard 115 V single-phase power. The extraction arm is designed with external adjustments to minimize airflow resistance, while the large bellmouth hood provides optimal capture velocity at greater distances from the arc. The cabinet itself is constructed from heavy-duty metal, mounted on large rear wheels and lockable front swivel casters, ensuring stability and ease of movement across uneven shop floors. With a sound level of approximately 70 dBA, it provides powerful extraction without contributing excessive noise to the facility.
