FilTek™ XL Filters

Cleaner Air with FilTek XL FiltersThe FilTek XL filter’s higher MERVrating means unrivaled filteringperformance.Filters are rated on a MERV scale, whichmeasures filter efficiency based on particlecount. MERV ratings range from 1 –16, with16 being the best at filtering small particles—such as those found in weld fumes. The vastmajority of weld fumes are less than onemicron in diameter, or roughly 1/100th thewidth of a human hair.

Filters in common air filtration systems often have MERV ratings between 7 –11.FilTek XL filters are rated at class-leadingMERV 15 –16 to capture up to 95 percent ofweld fume particulates.

The FILTAIR® Advantage

Exclusive hinged filter hatchfeatures a convenient locking mechanism for easy access to the filter and tool-free replacement.

Filter pressure gaugewith easy-to-read colorcode indicates whenpressure drop increasesand cartridge filter needsto be replaced (MWX-D)or cleaned (MWX-S).

Easy-to-operate extraction armwith external adjustments so air can passthrough with less airflow resistance,giving you stronger CFM (airflow). Itoffers reliable and accurate positioningacross the full range of motion of thearm, as well as easy adjustment andmaintenance to ensure long-lastingoperation. Pre-assembled extractionarms are available in 7-, 10- and 12-foot lengths.

Durable bellmouth-shaped hood features a convenient 360 degree rotation for unlimitedpositioning. One of the largest in the industry,FILTAIR’s extraction hood captures weld fumesat a greater distance from the source than otherhood designs. This also means less hoodadjustments for longer welds.

Built-in tool tray provides workers with aconvenient area to place their tools withoutthem rolling off of the unit.

Large rear wheelsallow for easy movementover weld cables and fromone work cell to another. Lockable swivel casters allow users to keep

fume extraction system stationary duringmovement of the arm.

Metal cabinet designensures long-lasting durabilityin a manufacturing environment.

Particulate disposal bin (MWX-S only)provides easy and convenient access toempty out collected particulate. Handlereleases drawer allowing it to slide out.

Power switch is conveniently located foreasy on/off access.

NEW! Preassembled arms forfast, easy setup.

115 VAC, 20-foot (6 m) power cord enableswelders to freely move fume extractor.

Convenient air connection (MWX-S only)for dry compressed air supply. Note: Compressed air required to operate cleaning mechanism.

Self-cleaning mechanism (MWX-S only) is easy to use. Just push button on controlpanel to activate the pulse cleaning cycle thatcleans the filter from the inside out. Weld fumeparticulate is removed from the filter and safelydeposited in the particulate disposal drawer.

Accu-Rated™

Performance Summary• The MWX design and ratings are

specific to weld fume capture. • While most extractors have CFM rated

at the blower, the Miller® MWX israted at 875 CFM at the capture hoodwhich is where suction is needed tocapture weld fume.

• The MWX is designed to exceed theACGIH recommended weld fumetransport velocity of 2000 feet perminute.

This results in the MWX havingstronger suction power for a cleanerwork space.
