  • 7 ft. Extraction Arm 8" Diameter
  • FilTek XL Filter
  • 17 ft. Power Cord
Easy-to-Operate Extraction Arm
With external adjustments so air can pass through with less airflow resistance, giving you stronger CFM (airflow). It offers reliable and accurate positioning across the full range of motion of the arm, as well as easy adjustment and maintenance to ensure long-lasting operation. Pre-assembled extraction arms are available in 7-, 10- and 12-foot lengths.
Preassembled Arms
For fast, easy setup
Durable Bellmouth-Shaped Hood
Features a convenient 360 degree rotation for unlimited positioning. One of the largest in the industry, FILTAIR’s extraction hood captures weld fumes at a greater distance from the source than other hood designs. This also means less hood adjustments for longer welds.
FilTek® XL Filter Technology
FilTek XL Filter Technology is specifically designed for welding fumes. This technology offers a longer filter life - up to 2 times that of treated cellulous filters and superior filtering of up to 95% of weld fume particulate.
MERV 15 Filter Rating
Filters are rated on a MERV scale, which measures filter efficiency based on particle count. MERV ratings range from 1-16, with 16 being the best at filtering small particles-such as those found in weld fumes.
Self-Cleaning Mechanism
The self cleaning mechanism is easy to use. Just push button on control panel to activate the pulse cleaning cycle that cleans the filter from the inside out. Weld fume particulate is removed from the filter and safely deposited in the particulate disposal drawer.
Hinged Filter Hatch
Features a convenient locking mechanism for easy access to the filter and tool-free replacement.
Metal Cabinet Design
Ensures long-lasting durability in a manufacturing environment.
Particulate Disposal Bin
Provides easy and convenient access to empty out collected particulate. Handle releases drawer allowing it to slide out.
Convenient Air Connection
For dry compressed air supply. Note: Compressed air required to operate cleaning mechanism.
Built-In Tool Tray
Provides workers with a convenient area to place their tools without them rolling off of the unit.
Filter Pressure Gauge
With easy-to-read color code indicates when pressure drop increases and cartridge filter needs to be replaced (MWX-D) or cleaned (MWX-S).
115 VAC, 20-Foot (6 m) Power Cord
Enables welders to freely move fume extractor.
Large Rear Wheels
Allow for easy movement over weld cables and from one work cell to another.
Lockable Swivel Casters
Allow users to keep fume extraction system stationary during movement of the arm.
Power Switch
Switch is conveniently located for easy on/off access.
