Mobile Fume Extractor uses MERV 15-rated nanofiber filters.

Press Release Summary:

Designed specifically for welding applications, FILTAIR MWX-D features 875 cfm airflow at hood and captures up to 95% of small welding fume particulates. MERV 15 rating means filter is 90% effective at filtering 0.3-1 micron sized particles found in welding fume. Extraction arm, available in 7, 10, and 12 ft lengths, is supported externally, so air flows through unobstructed. Additional features include filter pressure gauge and metal base with large rear wheels for mobility.

Miller FILTAIR(TM) MWX-D Mobile Fume Extractors Capture More Welding Fume Particulates Than Competitive Models

Miller's new FILTAIR MWX-D Mobile Fume Extractors use MERV 15-rated nanofiber filters to capture more of the smallest particles given off during welding.

Highlights/Key Facts

o Miller's FILTAIR is designed specifically for welding applications. Its MERV-15-rated nanofiber filters last longer and capture more welding fume particles than competitive fume extractors (MERV: Minimal Efficiency Reporting Value).

o Heavy-duty construction, including a durable, industrial-grade metal cabinet and extraction arm, designed to withstand the demands of everyday welding.

o Powerful 875 CFM combined with a large bell-shaped hood captures fumes at a greater distance with less repositioning.

A FILTAIR(TM) MWX-D Portable Fume Extractor provides a highly effective, easy-to-use fume extraction solution for fabrication, MRO and school and training applications.

Appleton, Wis., Luly 14, 2009-Miller Electric Mfg. Co. introduces the first product in its fume extraction line, the FILTAIR(TM) MWX-D Mobile Fume Extractor. The FILTAIR uses nanofiber filter technology to capture up to 95 percent of the smallest welding fume particulates, more than any of the competing brands. 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 several times longer. Typical cellulose filters fall in the range of MERV 7-10 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 on particles of different sizes. MERV ratings range from 1 to 16. A MERV 15 rating means the filter is 90-percent effective at filtering the 0.3- to 1-micron sized particles that are found specifically in welding fume.

The FILTAIR MWX-D features powerful 875-CFM airflow at the hood. The extraction arm is supported externally, so air flows through unobstructed, while the large, bell-shaped hood more effectively captures welding fumes at the workstation to achieve maximum efficiency.

Designed for an industrial environment, the FILTAIR features a heavy-duty, durable metal base with large rear wheels for easy movement from one weld cell to another. An easy-to read filter pressure gauge indicates when filters need replacing. The FILTAIR is available with 7-, 10- and 12-ft. extraction arms making it ideal for light manufacturing, MRO and general fabrication applications, as well as for educational facilities.

FILTAIRE spec sheet:

Product Manager Quote:

"The FILTAIR is designed specifically for welding applications and to meet the growing concern over air quality and welder wellbeing in the weld shop. Its MERV 15 rating means it captures more of the particles found in welding fumes than other brands. Most of the particles given off in welding are less than 1 micron and pass more easily through a cellulose filter, where they then circulate back into the shop to be inhaled by employees or drawn into equipment cooling fans."

Additional Product Information:

FILTAIR(TM) filters use nanofiber technology, which captures more of the particles emitted in the welding process. In addition, because they are surface loading, the filters maintain a nominal air flow longer than cellulose filters.

The FILTAIR's nanofiber filters are surface loading, meaning they keep the particles on the surface of the filter, allowing the filter to breathe 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.
