OVERVIEW

Breathe Clean, Weld Longer

Welding produces smoke and fumes that can be hazardous to your health and distracting to your work. The Miller FILTAIR® MWX-S is your mobile solution for keeping the air in your shop clean. Designed specifically for welders, this "Self-Cleaning" model takes the hassle out of filter maintenance. Instead of constantly buying new filters or manually banging out dust, you simply hook up a shop air line and press a button. The machine pulses air through the filter, knocking the dust into a drawer that you can easily slide out and empty. This keeps your suction strong and your filter lasting much longer.

Designed for the Shop Floor

We know shop floors are cluttered with cables, tools, and metal. That's why the MWX-S is built on a rugged cart with big back wheels that roll right over obstacles. The front casters swivel for tight turns and lock in place when you're ready to weld. The top of the unit even has a tray for your grinder, chipping hammer, or gloves, so you aren't searching for tools in the middle of a job.

Superior Filtration

This unit uses Miller's FilTek XL technology, which is rated at MERV 15. In plain English, that means it captures 95% of the tiny particles in weld smoke that other filters miss. Whether you are Stick welding, MIG welding mild steel, or TIG welding stainless, this extractor helps protect your lungs. Note: This is the power unit only; make sure to grab the extraction arm length (7ft, 10ft, or 12ft) that fits your workspace best.

FAQ

No, this specific SKU (300531) is the base unit only. You must purchase a pre-assembled extraction arm (available in 7, 10, or 12-foot lengths) separately.

The unit requires a connection to dry compressed air. When the cleaning button is pressed, a pulse of air is released inside the filter, blowing dust off the outer surface and into a collection drawer.

The FilTek® XL filter has a MERV 15 rating and is capable of filtering up to 95% of weld fume particulates.

The MWX-S operates on standard 115/120V, 1-Phase, 60Hz power.

The unit features a front-mounted filter pressure gauge. When the pressure drop increases into the indicated range, it is time to run the self-cleaning cycle.

While it can handle incidental grinding sparks if properly positioned, it is primarily designed for weld fume. Dedicated grinding tables or down-draft benches are better for heavy grinding applications.

Thanks to the self-cleaning mechanism and surface-loading FilTek XL technology, the filter lasts up to 2 times longer than standard treated cellulose filters. Replacement frequency depends on usage volume.

Yes, it weighs approximately 300 lbs but is mounted on a cart with large rear wheels and swivel casters, making it easy to move around a level shop floor.
