Wall-Mounted Fume Extractors


Miller Electric Mfg. Co. introduces the new FILTAIR™ SWX-series of space-saving wall-mount welding fume extractors, featuring Miller’s exclusive nanofiber filter technology. Available in either the self-cleaning SWX-S model or the disposable filter SWX-D model, the SWX-series allows companies to improve air quality and protect employees without cluttering their shop floors.
Like the mobile FILTAIR MWX-series, the SWX-series uses surface-loading nanofiber filters designed specifically to capture the sub-micron particles found in welding fumes, including hexavalent chromium and manganese. Because the nanofiber filters are ‘surface-loading,’ they offer more holding capacity and less pressure drop than competitive, ‘depth-loading’ fume filters.
The SWX-S and SWX-D provide 875 CFM (cubic feet per minute) airflow for excellent fume removal up to the maximum recommended hood distance of 14 inches from the welding arc. Designed for heavy-duty industrial use, both models are suitable for continuous filtration of Stick, flux-cored, MIG and TIG fumes. 
For added application flexibility, both SWX models are available with one or two extraction arms that come in lengths of 7, 10 or 12 feet. The extraction arms are designed to stay in position and won’t sag over the course of the day.
The SWX-S model features an innovative ‘pulse-jet’ cleaning mechanism that removes fume particles and restores the filter in approximately one-minute, significantly reducing the downtime associated with filter changeovers and the self-cleaning cycles of competitive products.
SWX-series products are covered by a one-year parts and labor warranty.

Product Manager Quotes
“We understand that employers care about the health of their employees, and in that spirit Miller offers the most durable, highest performing fume extraction products available. Featuring our exclusive nanofiber filters, the SWX-series of fume extractors reflects this commitment while also recognizing the importance of maintaining a clean and uncluttered shop floor.”

Additional Product Information
The FILTAIR SWX-series uses nanofiber filter technology to capture up to 95 percent of the smallest welding fume particulates. Welding fumes contain particles of different sizes, up to 90 percent of which are smaller than one micron (.000001 of a meter). Rated at MERV-15 (ASHRAE’s Minimal Efficiency Reporting Value) the FILTAIR filter captures more particles at that size than cellulose-type filters and lasts longer. Typical cellulose filters are not even MERV rated and are designed to capture larger, dust-sized particles.
    MERV is an ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) standard used to classify filters based on their air-cleaning efficiency for different sized particles. MERV ratings range from 1 to 16. A MERV 15 rating means the filter is up to 95 -percent effective at filtering the 0.3- to 1-micron sized particles that are found specifically in welding fumes.
The FILTAIR’s nanofiber filters are surface loading, meaning they keep the particles on the surface of the filter, resulting in lower pressure drop and allowing the filter to breathe more freely longer. Most competitive models use cellulose or pretreated cellulose filters, which are depth loading, meaning they pull the particulates deep into the filter where they more quickly clog the pores, reducing their filter lives. Along with the nanofiber filter, FILTAIR machines are designed to maximize the airflow efficiencies, resulting in longer lasting suction power.
