Fume Dog Magnetic Wall Mount Weld Fume Extractor with Filter

The Wall-Mounted Welding Fume Extractor That Moves With Your Work — Not Just Your Arm.

The Fume Dog Bulldog-FILT-FLEX delivers 1,200 CFM of wall-mounted fume extraction with multi-stage HEPA and carbon filtration — and adds something no standard wall-mount unit offers: a magnetic aluminum hood that attaches instantly to any metal surface, letting you reposition the capture point wherever your weld is, without adjusting the arm. It's the setup for welders who move around a booth and need their fume extraction to move with them. 

[Return Policy exception: Fume Dog products are an exception to The Maker's Chest standard returns policy, and all sales are final. However, this does not mean we do not have confidence in these products - in fact, the Fume Dog products come with a 10-year warranty on all major structural components.]

What "Magnetic" Actually Changes for the Welder

Standard articulating fume extractor arms work well when you stay in one spot. But real welding isn't stationary. You move along a joint, you shift your position, you weld on different sides of a fixture. Every time you move significantly, a standard arm needs to be readjusted — and in a real production environment, that interruption adds up.

The magnetic fume hood is crafted from aluminum and equipped with magnets, allowing it to adhere to any metal surface in your welding area: the table surface, a fixture, a steel shelf, a booth wall, a part itself. The 360° rotating snorkel on the magnetic base positions the capture inlet precisely where fumes are rising, at whatever angle works for the weld.

The result: the capture point moves when you move your work setup — not just when you physically reposition a 10-foot arm. For welders working inside booths, on large assemblies, or across varied fixture heights, this is a genuinely different experience from a standard arm extractor.

1,200 CFM. MERV 15 Filtration. No Ducting.

The power unit behind the magnetic hood is the same 1.5 HP motor, 1,200 CFM platform as the rest of the Bulldog wall-mount line — a serious industrial extraction capacity that fully supports the 8-inch arm diameter required to move that airflow without pressure drop.

The filtration system uses a MERV 15, nanofiber, fire-retardant filter — a high-efficiency configuration capable of capturing very small particles, making it suitable for environments where air quality is crucial. This is notably a step up from standard HEPA in some configurations, paired with an activated carbon stage for gases, ozone, and odors. Filtered air is returned clean to your shop — no ducting required, no wall penetrations, no conditioned air pushed outside.

The filter outlet is configurable to exit from the left or right side of the unit housing, adapting the installation to your available wall space.

Wall-Mounted Base, Magnetic Hood — Two Layers of Flexibility

The Bulldog-FILT-FLEX is wall-mounted at the motor and filter housing, which keeps the heavy components stable, off the floor, and out of your way. The integrated steel wall mount bracket is part of the housing — not a bolt-on accessory — and is built for the unit's 215 lb weight.

From that fixed base, the 10-foot articulating arm reaches across the work area with external joints for positioning and a built-in internal damper for airflow adjustment. At the end of the arm, the magnetic aluminum hood detaches and repositions independently — sticking to any metal surface near the weld puddle.

This two-layer system gives you the stability and extraction capacity of a wall-mount unit, combined with the capture-point flexibility that standard arm extractors simply can't match inside a busy welding booth.

If wall mounting isn't feasible for your space, the optional 8-foot floor-mounted stand converts the unit to a pedestal configuration without any modification to the machine itself.

Built for Welding Booths and Enclosed Stations

The Bulldog-FILT-FLEX is especially well-suited for environments where the welder and the work are in a semi-enclosed booth or defined station:

Welding booths in fabrication shops — the magnetic hood attaches inside the booth, captures fumes at the exact work point, and the filtered unit on the wall keeps floor space clear for movement.

Welding schools and training centers — students at fixed stations work with varied fixture heights and positions. The magnetic hood adapts to wherever the student is welding without requiring constant arm readjustment by the instructor.

Multi-axis and fixture welding — for assemblies welded from multiple angles or heights, the magnetic hood can be repositioned between weld passes in seconds, keeping extraction effective throughout the job.

Frequently Asked Questions about Fume Dog Magnetic Wall Mount Weld Fume Extractor with Filter

Q: What makes the FILT-FLEX different from the standard Bulldog-FILT?

A: The standard Bulldog-FILT has a traditional 10-foot articulating arm with a fixed hood at the end. The Bulldog-FILT-FLEX replaces that fixed hood with a magnetic aluminum hood that detaches from the arm and attaches to any nearby metal surface — the welding table, a fixture, the side of a part, a booth wall. This gives you independent positioning of the capture point without moving the full arm, which is particularly useful in welding booths and enclosed stations where the work position changes frequently. The motor, filtration system, and extraction capacity are the same on both units.

Q: What surfaces does the magnetic hood attach to?

A: Any ferrous metal surface — mild steel tables, steel fixtures, steel booth walls, steel shelving, and most steel workpieces. It will not attach to aluminum, stainless steel with low magnetic permeability, wood, or non-metal surfaces. For most welding environments, attachment options are abundant. If your specific setup uses non-ferrous surfaces extensively, contact us before ordering to confirm the magnetic hood will work for your application.

Q: Does this unit require ducting?

A: No. The Bulldog-FILT-FLEX is a filtered recirculating system — it processes extracted air through the multi-stage filter stack and returns clean air to your shop. No ducting required, no wall penetrations, no outdoor exhaust connection. Mount it to the wall, connect power, and it's operational.

Q: What filtration does it use?

A: A multi-stage system featuring a MERV 15 nanofiber, fire-retardant primary filter — high-efficiency filtration rated for very fine particles including metal fume particulates — combined with an activated carbon stage for gases, ozone, and odors. MERV 15 is a step above standard HEPA in some applications, particularly suited for welding environments where fine metal oxide particles and gases are both present.

Q: What welding processes is it rated for?

A: MIG, TIG, and Stick welding at one to two shifts per day. The internal damper lets you reduce airflow for TIG welding to protect shielding gas coverage. Not recommended for plasma cutting or carbon arc gouging, which produce fume volumes and spark concentrations beyond the unit's design parameters.

Q: Can the filter outlet be positioned on either side?

A: Yes. The filter housing is field-configurable to exit from the left or right side of the unit, letting you adapt the installation to your wall space and room layout without repositioning the unit itself.

Q: Can it be floor-mounted instead of wall-mounted?

A: Yes. An optional 8-foot floor-mounted stand is available as a configuration option at checkout. This converts the unit to a pedestal setup with no modification to the machine. Useful if your wall structure doesn't support direct mounting, or if you want the base unit to be repositionable over time.

Q: How is the magnetic hood different from a standard articulating arm hood?

A: A standard articulating arm has a fixed hood at the end — to reposition the capture point, you move the arm. The magnetic hood on the FILT-FLEX detaches from the arm and sticks independently to any nearby metal surface. This means you can reposition the capture inlet in seconds without touching the arm itself — a significant time-saver when you're moving through multiple weld passes at different positions on the same assembly.

Q: What power does it require?

A: 120V, single-phase — standard shop outlet power. The 1.5 HP motor is appropriate for a standard 20A circuit. Other voltages are available; contact us before ordering if your facility operates on a different standard.

Q: What is the Returns Policy on the Fume Dog?

A: Given the nature of how a fume extractor is used, it is no longer a "new" product after first use, given contaminants which enter the filtration system. As such, Fume Dog products are an exception to The Maker's Chest returns policy, and all sales are final.
