MWX-S Model Self-Cleaning Filter Technology
Miller’s FILTAIR MWX-S features an innovative filter cleaning mechanism designed to increase productivity and greatly extend filter life. A fast, one minute cleaning cycle is all it takes to remove weld fume particles from the filter.

Because Miller’s nanofiber filter is surface loading, weld fume does not penetrate deep into the filter. This enables particles to be easily released during the cleaning process and keeps pressure drop low.

One minute cleaning cycle greatly reduces downtime (competitive models can take up to 45 minutes).

Up to 50% more media than competitive models means less cleaning and extended filter life.

Nanofiber filter is surface loading meaning weld fume doesn’t become embedded and is easily released off the filter during the pulse cleaning cycle.

Disposal drawer provides convenient way to periodically remove fume particulate following automated cleaning cycles.

Cleaner Air
FILTAIR fume extractors effectively clean welding fumes from the air. Combining nanofiber filter technology, longer lasting airflow, and an optimized design results in a more powerful fume extraction system.

Superior Filter Efficiency
Miller’s exclusive MERV 15 nanofiber filter
ensures capture of submicron weld fumes,
more holding capacity and the ability to
maintain low pressure drop—resulting
in a longer lasting filter and a cleaner
work space.

What is Nanofiber Technology?

Nanofiber at 600X. Nanofibers use an exclusive media blend that features a surface layer of nanofibers about 1000 times thinner in diameter than a human hair.

Nanofiber cartridge filters use a surface webbing of very small fibers to capture weld fume particles of all sizes, including submicron particles (.3 to 1μm), which represents more than 80% of weld fumes. A nanofiber filter is surface loading, meaning they keep the particles on the surface of the filter, instead of becoming embedded deep within.

Strong Suction Power
Powerful 875 CFM system delivers
long-lasting airflow throughout the life
of the filter.

Reliable Extraction Arm
Optimally-designed extraction arm stays
in position and will not slouch over time.
Arm also comes partially assembled to
reduce set up time.

Saves Operator Downtime
From easy set up, simple front panel,
quick, convenient, and tool-free filter
replacement, FILTAIR is easy to use.

Durable Construction
Industrial-grade metal cabinet and
extraction arm withstand the demands
of everyday welding.
