Description
MFE-750 Mobile Fume Extractor — 750 CFM, 120V Single-Phase
If your shop runs all day, the little units choke. The MFE-750 pulls 750 CFM right at the hood and plugs into a regular 120V wall outlet — no electrician, no 3-phase drop. Go disposable filter to keep the upfront cost down, or self-cleaning if you’re tired of pulling cartridges every couple months.
Watch it run — 750 CFM of pull off a regular wall plug.
Same unit, two ways to handle the filter.
The MFE-750 sits right between the ELEVENT (400 CFM, fine for a part-time station) and the MFE-1350-SC (1,350 CFM, but you need 3-phase to run it). Both 750s are the exact same machine underneath — same 1.5HP motor, same 120V plug, same 750 CFM, same 6″ arm. The only thing that changes is how you keep the cartridge from plugging up.
MFE-750 — Disposable Filter
Cheapest way in the door. The MERV 15 cartridge grabs the fine fume until it loads up, then you pull it and drop in a new one. Cartridges run $464-506 and we stock them in Arizona, so you’re not waiting two weeks for a filter. How long one lasts comes down to how hard you weld — figure 4-8 months running production, a year or more if it’s part-time.
Get this one if: Money’s tight, you weld 1-3 hours a day, there’s no air line where the unit sits, or you’d just rather buy a filter now and then instead of paying for a cleaning system up front.
MFE-750-SC — Self-Cleaning
This one cleans its own filter. A shot of shop air blasts backward through the cartridge and knocks the caked-on fume down into the drawer. Hit the button at the end of the shift — or whenever the gauge tells you it’s getting tight — and you dump the drawer instead of buying a cartridge. Stretches filter life out to 18-30 months on production work.
Get this one if: You’re welding 4+ hours a day, you’ve got 80-100 PSI air at the unit, and the filters you’d buy over two years cost more than the upgrade. For a busy shop, that math almost always lands here.
Every number, so you can spec it without a phone call.

Is 750 CFM enough pull for what you weld?
It’s simple: the unit has to pull air faster than the fume floats up, at whatever distance the hood sits from the arc. You want 100-150 fpm of pull about 6-12 inches off the puddle. A 6″ hood at 750 CFM hits that with room to spare — get it close and the fume’s gone before it reaches your welder’s face.
✔ Right-Sized For
MIG welding mild steel up to 1/2″ thick · TIG welding aluminum or carbon steel · Stick welding general fabrication · Plasma cutting up to 1/4″ steel · Grinding and finishing · 6″ hood positioned 8-12″ from work
× Undersized For
Heavy plate welding (3/4″+) generating high fume volumes · Continuous flux-core welding 6+ hrs/day · Multi-station setups · Hood positioned 18″+ from work · Heavy stainless production (still 750 CFM but switch to HEPA configuration)
↑ Step Up To
Need more than 1,000 CFM? The MFE-1350-SC pulls 1,350 but wants 460V 3-phase. Got several fixed stations? At that point a central collector with hard pipe is cheaper to run than a unit per bench. Call us at 602-456-9661 and we’ll keep you from buying the wrong thing.
Who’s buying the MFE-750 series.
Custom Fab Shops
Welding mild steel and aluminum 4-8 hours a day. The self-cleaning unit means you’re dumping a drawer, not buying filters every month.
Auto Body & Collision
Frame work and structural welding that loads up an ELEVENT’s filter way too fast. This one keeps up.
Trade Schools
Six-plus student booths going all day. Self-cleaning gets you through the whole school year on one set of cartridges.
Maintenance Crews
Repair welding wherever the breakdown is. It’s on casters and runs off any 120V outlet, so it follows you across the floor.
When the MFE-750 series is NOT right for you.
- You’re running 1+ coil of MIG wire per week. That’s intensive production. Step up to the MFE-1350-SC for the bigger motor and dual cartridge filter system, or look at central cartridge collection.
- Your facility is 3-phase only. The MFE-750 series is 120V single-phase. The MFE-1350-SC is the 3-phase option in this lineup.
- You weld stainless without HEPA. Hexavalent chromium and nickel oxide require HEPA filtration to meet OSHA PEL. Spec the HEPA configuration when you order — don’t skip it.
- You’re working with combustible dust. The MFE-750 series is a welding fume extractor, not rated for combustible dust applications. Combustible metal dust (aluminum, magnesium, titanium grinding) requires NFPA 660 compliant wet collectors or baghouse systems with explosion protection. Call us at 602-456-9661 before you buy anything for combustible dust work.
- You have 4+ welding stations at fixed locations. Central cartridge capture with hard-piped ductwork is more economical long-term and gives you better capture. We design those too — see cartridge collectors.
- Self-cleaning version: you don’t have compressed air on the floor. The pulse cycle requires 80-100 PSI. No compressor? Spec the disposable MFE-750 instead, or look at the i-Portable.
What OSHA actually wants to see.
Weld fume is full of stuff OSHA cares about — hex chrome, manganese, nickel, iron oxide. Pulling it at the source is how you keep your guys under the exposure limits without strapping a respirator on everybody for the whole shift. Here’s the short version of what the rules say and how this unit handles it.
OSHA 29 CFR 1910.252 — Welding Ventilation
If you’re welding stainless, galvanized, painted, or coated metal, OSHA says you need mechanical ventilation — full stop. Get the hood within a foot of the arc and the MFE-750 pulls the fume off the puddle before it hits your welder’s face. That’s what keeps you off OSHA’s radar on general fab work.
OSHA Hex Chrome PEL (1910.1026)
The limit is 5 µg/m³ averaged over an 8-hour day. Weld stainless with no capture and you’ll blow past 50 µg/m³ — ten times over. Spec the HEPA filter for any stainless work and you’ll be sitting well under the line.
NFPA 51B — Hot Work
Covers spark control in hot-work areas. The washable aluminum pre-filter knocks down the sparks before they reach the cartridge. You still need your 35-foot clear zone and a fire watch to be square with 51B — the unit doesn’t replace those.
NFPA 660 (effective Jan 1, 2026)
This is the new combustible-dust standard that rolled 652, 654, 664, and 484 into one book. It doesn’t apply here — the MFE-750 is a weld fume unit, not a combustible-dust collector. If you’re grinding metal and aren’t sure which bucket your dust falls in, call us at 602-456-9661 before you spend a dime.
What it’ll run you.
The MFE-750 lands between $9,349 and $13,049, depending on disposable vs. self-cleaning, arm length, and whether you add HEPA. Build it out at the top of the page and you’ll see the real price for your combo — no “call for pricing” games. Every build ships free to AZ, CA, NV, NM, and UT.
Bare-Bones Build
$9,349
Disposable filter, 6″×7′ arm, MERV 15. Cheapest way to get real pull on the floor.
The One Most Shops Buy
$12,019
Self-cleaning, 6″×10′ arm, MERV 15. The go-to for a shop welding every day.
Stainless Setup
$13,049
Self-cleaning, 6″×10′ arm, with HEPA. What you need to run stainless and stay under the hex chrome limit.
Put that next to a central system: tie one welding station into a cartridge collector and by the time you’ve paid for duct, electrical, and engineering you’re looking at $35,000-$60,000 installed. If your work moves around the shop, the MFE-750 earns its keep on mobility alone. See the full cost guide →
Real questions buyers ask before placing an order.
What’s the difference between the disposable MFE-750 and the self-cleaning MFE-750-SC?
Same chassis, motor, CFM, and power supply. The disposable version uses a MERV 15 cartridge that you swap out when it loads up — typically 4-8 months in production, longer in light duty. Replacement cartridges run $464-506 each. The self-cleaning version adds a reverse-air pulse system: a burst of compressed air cleans the cartridge in place, extending filter life to 18-30 months. The SC version costs about $2,600 more upfront but typically saves $1,500-2,500 over 24 months in filter replacement costs for production shops.
Does the MFE-750 need 3-phase power?
No. Both the MFE-750 and MFE-750-SC run on 120V single-phase, 20A — standard outlet (NEMA 5-20). For 3-phase performance with 1,350 CFM, the MFE-1350-SC is the right step up.
Does it come with the arm and hood included?
Yes. Every MFE-750 ships complete: extractor unit + your selected 6″ standing arm (7′ or 10′ length) + extraction hood + filter installed. Plug in, position the hood, and start welding. No assembly beyond unbolting the arm from shipping protection.
Can I weld stainless steel with this?
Yes — with the HEPA configuration. Stainless welding generates hexavalent chromium and nickel oxide, both regulated by OSHA at very low PELs. Standard MERV 15 filtration captures most of it but not all. For consistent compliance, order the HEPA upgrade. The HEPA filter is factory-installed downstream of the cartridge and captures 99.97% of 0.3-micron particles.
Does the self-cleaning version need compressed air?
Yes. The reverse-air pulse cleaning cycle requires 80-100 PSI compressed air, typically 5 SCFM. Most production facilities have shop air; some smaller shops don’t. If you don’t have compressed air at the unit’s location, the disposable MFE-750 is the better fit — same airflow, no cleaning system, just swap cartridges when they load up.
How long does the filter cartridge last?
Disposable MFE-750: typically 4-8 months in production welding (4+ hours per day), 12+ months in light duty. Self-cleaning MFE-750-SC: typically 18-30 months in production with daily pulse cleaning, often 3+ years in light duty. Filter life depends on fume load and how often the self-cleaning system is pulsed. Replacement cartridges run $464-506 and stock in Arizona for fast delivery.
What’s the lead time and shipping cost?
3-5 business days from order to ship, plus 3-5 business days in transit to AZ, CA, NV, NM, UT via LTL freight. Total order-to-dock: 6-10 business days. Free shipping is included in the price for AZ, CA, NV, NM, UT.
