- *CAUTION* Please make sure to ground the electrical system. I missed that in the video however went back and corrected it.
I'm working on a new metal sculpture that will require a great deal of welding and with that comes a lot of smoke. So I had to build an extractor that could remove all of that smoke. After a quick search online and finding that most extractors were outside of my budget, I decided to build my own.
Here's a list of all the parts I used. These are Amazon affiliate links which provide me a percentage of a sale if you choose to click on any of the following links.
1450 cfm Attic Fan
amzn.to/2RV62Vz
12" x 10" duct reducer
amzn.to/2DjPvm6
10" x 8" duct reducer
amzn.to/2Dim2J6
8" x 6" duct reducer
amzn.to/2DlnAlK
25' x 6" flexible duct
amzn.to/2S2SebX
6" 90 degree duct fitting
amzn.to/2T33Fh1
The electric parts are fairly standard and are easily found at the local hardware store.
Single junction box
single pole 15amp switch
1/2" strain relief

Been looking for a while to see if anyone has done something like this, finally found this video.. Straight to the point with great demonstration of expertise and experience, freakin' perfect. Thank you!
Excellent. Glad it might help. A quick note, make sure to ground your electric. I didn't show that in the video
Great content! I like how you get straight to the point and start the build, also the lack of annoying background music is another plus👍
Thanks Oscar, greatly appreciated
I don't know how I found or why I'm watching this but at least now I have an idea on how to extract smoke and fumes from my studio. Entertaining none the less my guy
Cool thanks. I'm glad checked it out
Great how-to video Doug. I basically used your tips to build a fume extractor in my shop. I have quite a bit of metal that I have accumulated over the last 20 years. I had an old patio heater like you see in all the big box stores. The burner was shot. Using the exact same fan you did, I used the bottom cover of the patio heater (the part you lift and lower to change out the propane tank). It is the exact size to squeeze the fan into after I zipped a 8" hole in what used to be the top of the cover with my plasma cutter. Let me back up some, I tried a mock-up with 6" hard duct and one 8 foot piece of 6" flex duct. I discovered that 6" duct was just too restrictive and greatly reduced the 1500 cfm of the fan. And the flex duct works good as long as you don't have any sags or sharp turns, it works best extended. I ended up using 18 feet of 8" hard duct and one piece of 8" flex about 5 feet long. It performs great and is whisper quiet. The center cap from the umbrella on top of the patio heater is aluminum and the perfect size for the hood at the extraction/suction point so I zipped another 8 inch hole in it and used a 8" airtight take-off to connect it to the hood and then to the 8" flex. You are correct at the end of your video about changing the flex out for hard duct but I would also recommend going to 8".
Thanks for your content, I always enjoy it and/or learn a thing or two.
Wow very cool and I really like the changes you made
Smart way to go. I know a guy who welded for decades and got messed up from heavy metal poisoning.
Its the unseen stuff that gets ya
great design! simple, easy to fab, cost effective and totally functional! I saved your vid for when I’m ready to build my own. Thanks!
Glad it helped!
Great build. Attic fan for shop exhaust.... Now I need to make some attic fans for my attic!
Great video - clear and to the point, you do a great job explaining everything. This gives me some great ideas for my vehicle exhaust system so I can continue working on motorcycles in my garage in the winter.
Glad it was helpful! Seems like it might work good at removing the exhaust fumes
Thank you so much for taking the time for making this video!
Thanks for taking the time to watch Victor
thanks for the tips. building a fume extractor using ridged ducting at the moment. will try and get some video uploaded soon.
Cool! Hope it all goes as planned Keith
Thank you! This is exactly what I’ve been looking for.
Excellent! I'm glad it helped.
Fantastic job! I've been looking for ideas to vent my garage, mostly because of heat reasons and my upright freezer having a hard time with this recent Texas heat(100+ for two weeks now every day). I was looking to fabricate an exhaust fan in a similar fashion. Thanks for the video, great content and superb results!
Thanks! Yeah I grew up in Texas and my family told me how hot its been there
Wonderful work, really nice video. I am setting up a fume extractor for electronics soldering. While doing research for that I saw some REALLY expensive prices for welding fume extractors. I need to build an arm like yours but a scaled down version. Cool Vise Grip counter weights.
Great work, I did the same thing, I would suggest you add a carbon filter to the end point, and if you decide to do that I would also suggest that you move your suction tube further from your desk to avoid burning the carbon filter.
This is just what I need! I do stained glass and need a homemade fume extractor out my basement window.
Cool, glad it might have helped a bit
Brilliant.... now I have to build one!! Thanks for the motivation
Heck yeah Joe, and it was a fairly quick build. Would've only taken a day had I not been slowed down by having a few beers :)
Awesome idea! Great work on the project and on the video!! Thank you sir!
Hi sir. I am very much grateful for this video! It helped me so much think of an idea on how to innovate my stove. Im using your video as my basis for my research. Thanks a lot😊 Subscriber here😍
Cool! I've been brainstorming how to do this in my new shop. Just scored two 8" inline fans from my landlady to power the system (one for welding, one for plasma table). Just a word of caution, might want to upgrade to traditional wiring with a ground wire or use and extension cord with a ground for the switch and fan. If that fan somehow ends up becoming live, which isn't too bigger of a stretch to imagine given its all metal and vibrating constantly while on, it could get you pretty easily. Say you're leaned against your table with the welder ground clamp connected to the table and go to adjust the exhaust tube above the table... Zappo. Pretty crazy cool how well that system appears to work! Excited to get my head out of the clouds in my shop.
I totally see what you're saying. I'm not sure the current would be able to travel through the ducting though. Since the video was shot, I have rewired the fan with a grounded wire
@@ArtfullyRogue Good you took their advice. The ducting is metal so it's conductive and current would travel through it. Thanks for the video. I'll be making an exhaust system like yours when I start my new hobby of welding!
Smart idea, great execution. Thanks for the video.
Thanks David...necessity is the mother of all invention :)
Dude that was pretty good. I am going to try something like this soon. That is why I looked it up ofcourse lol. Thank you! 😁
Cool thanks for watching
Got here from a electrical video because the orange tapes.
But, maybe I am too late (3 months), you may want to add a funnel at the start of the suction tube (where the smoke enters).
It will increase the area it covers.Both wide and distance from welding point.
Well detailed video.
Seems strong! Might copy that for a budget setup👌
Yeah compared to what I saw online, I only spent about $150 on this setup
Very well made. Will be making one too. Thanks for the video
Thank you very much! I love mine for sure
Looks great, thank you for sharing
I'm doing one myself but I used a down draft range fan as my fan. I use a timer and let it run for whatever time I want so I don't have to worries about unplugging each time
Yeah adding a timer would be a good thing on mine as well
I set up my shop ventilation using one of those duct fans about a year and a half ago. The problem I found is that the smoke and particulates that are sucked out also attack the fan bushings. The rig seized up after about one month. I rebuilt the fan and then had to jury rig a cover to protect the bushings. That lasted about one year and I got to rebuild the fan again. It finally died for good a few weeks ago. Hopefully you have a better experience. Cheers.
I'll have to keep an eye on mine to see how it does.
Thanks for this video. I have been thinking about extraction and this looks like it will work for me. I think I’ll add a remote control switch, but other than that, I like!!
Cool! Yeah it has made a world of difference in my shop
I like your"s video because execution it"s simple and good working job.
Everything as tools and parts possible buy at local store.
In Your shop ain't. Its great and i like this !!
Sorry for my english.
Thanks a ton for watching Max and you're English fine, I totally understand what your saying :)
Beautify explained and shown step-by-step. Thanks for taking time to make this video. 😃👍
Thanks, greatly appreciated
Great idea, thanks. I would recommend you something for this design, make a rack for the duct and complete the base for the fan, this will improve the strength of your ventilation system. Remember that the mechanical vibration and the force of the air will damage the structure, so improving your design will protect of that. Saludos desde México.
Great Idea Doug..i have a neederman portable extraction unit that costs a fortune for filters. i think i will copying your idea and put one in the shop just like yours. Thanks for sharing this buddy :)
I have to say it has been working great, I love that it's not smoky in the shop anymore
The orange tape is actually a nice touch!
Haha yeah I thought so as well. It was either orange or green.
Seems to work quite well
I’ve been planning one too. While it’s not really needed for TIG and most MIG, for flux core and the little bit of stick I do, it really is. I’ve been concerned about two possible problems.
One is the hot particles vaporized in the welding fume. That consists of metallic compounds as well as compounds from the flux core, or stick coating. This could damage the motor, because they’re not designed for this much crap in the fume from our furnaces. So I plan on using a furnace filter in front of the fan. A furnace filter designed for oil, or even coal burning (shudder) heating systems should help, though not perfectly.
The second is blowback from the open door. It seems that whatever I blow out comes back, at least, a lot of it, depending on which way the breeze is blowing.
For the blowback problem, I plan to remove two panes from the window, which gives me almost the exact size opening I need. I’ll put a shutter on the outside. I found some nice furnace fans on eBay with speed controls for about $100, depending on size.
Im not sure where you are, so some of these problems may not apply to you. But for me, in New York, it’s a problem. Good project. I’ve been waiting too long to do mine. Now, having watched you here, I’m motivated to get mine done.
good luck with yours! I use mine often and love it!
Good video and good project. Lots of valid safety comments before mine...appreciate you answering ALL of them! Don’t forget to take care of your skin as well as your lungs..all of your welding was in a t-shirt! Lots of kids may see this and think that’s ok, but career welders today are having skin spots&bumps removed because of the lack of proper PPE (ie long sleeve shirts). Anyway...good channel and videos. Keep it up! Cheers.
Great point! Thanks
Very Innovative, thanks for the video!
Thanks Frank
Congratulation for your work
a metal covered swicth can be dangerous. Good job. Thanks for video.
Thanks
I like it. I’m going to use your idea. Thanks
Cool Go for it!
Doug, wicked use of over the counter hardware. I was going to stop by the shop, unfortunately by the time I was buy your shop. It was like 2:30 am. I’ll try next time for a better time.
Cool, I totally understand. see you next time around
We've been looking forward to this since you talked about it on Instagram. Holy Smokes (pun intended), that thing works great!
I am so freaking happy with this thing, I should have done this years ago
Brilliantly done , forgive me for chipping in my two cents but could I recommend a centrifugal fan , the fan blade geometry is set up for high static pressure
Thanks for the suggestion James.
I was thinking the same thing. A centrifugal fan is much better for pulling air through flexible duct work.
Axial fans are for high flow low restriction applications.
@@mattburrows2615 i agree but how does the normal guy know what size of squirrel cage fan to buy lol.
@@derekmoen5382 generally one one would ask someone or look at what others have used for the application in mind. Search the internet pictures and simple specs really isn't hard. That excuse doesn't fly when it's the information age lol.
Even if he didn't do any of that and wacked whatever one would fit the ducting he most likely wouldn't be far off.
@@mattburrows2615 haha, okay. so how many f'ing years should i spend looking? wada!
Looks like AZ!
Edit: it is! Just saw your PO box. I'm currently a welding student, If you're ever in need of a second set of hands, let me know. I'm not far from deer valley airpark.
Cool thanks Michael! I might just take you up on that sometime
This is a really smart idea. I would love for you to do this for car exhaust. Need to find some way to vent it without having to open the garage doors here in the Northeast
That's a great idea! I wonder if you could use something like a dog door that can be open and closed as needed
@@ArtfullyRogue Yes! Thought about that too
how about driving into the garage with the front of the car first? and open the door before starting the car.. works for me..
Great job,..the answer to my question. Top notch idea.
I'm going to subscribe now and ring the bell to see what else comes along.
Thank you!
Thanks for the sub! And I'm glad the video was useful
@@ArtfullyRogue Cheers, I am out and about soon to pick up those supplies so that I can make one of those 'extractors' as you've shown..
If nothing else, it a great project.
Good build. Welders, or anyone who even hobby welds enough: control your fumes! Particulates and gas/metal fumes are the final realm of safety that welding culture is finally recognizing. The majority of long-term illnesses associated with welding are mostly from inhaling such fumes/particles. Metal particulates are small enough to permeate the blood/brain barrier and fumes from most any welding is poisonous in some amounts. Long-term exposure is very detrimental. I personally work with two old-timer metal fabbers/welders (both in 60s): one of which had to retire after developing COPD, the other has tremors and neurological issues. The third old-timer is in good health, plays pickleball, and, when referenced, is always mentioned for his rigorous use of safety equipment, respirators and ventilators included.
safety first for sure, although late in the game it has become a priority
Awesome video. Wanna try a smaller version for an indoor smoking room.
Very cool sounds like a good use of the extractor fan :)
Great content, well detailed as well...with reducing the diameter from the fan, down to the 6" ducting...how much of an increase in velocity/ suction do you believe you received?
It works exceptionally well, I would weld more if I was able to extract the smoke as you do...throughout the winter here.
Thanks again for sharing.
Nice setup
Thanks!
Clever! Thanks for the great tip!
My pleasure Jim, thanks a ton for watching
Great video. Thanks!
Glad you liked it! Thanks Stephen
ty. very well composed, everything
Thanks Chance
I think I might build one like your but probably buy an articulating arm for the tube. If you look on Amazon for articulating floor lamp you can find one to attach the tube to and the light is a bonus although it might not last long with all the hot flying metal. They only cost about $40. Also I will add a wireless remote to turn it on and off. A lot of the remote outlets are super cheap and can be controlled from your smart phone.
i think its better if you connect the smock extractor below the table , for best gas flushing
awesome setup. will do the same just a bit smaller hello from Australia
It has worked well for me for sure
Thanks this inspired me to construct something similar !
Thanks Donny
@@ArtfullyRogue No, thank you !!!! Kindly .
Thank you. Great video.
Glad you liked it! Thanks Mar K
That’s wicked nice
Yes it is...finally no more smoky shop
Doug always 😎👍, Thank you !!
Cool Thanks Barry
dude, i like this stuff. Subbed.
Thanks for the sub Dave!
Nice. Simple and cheap.
Indeed! and it works great
Super idea i leran More i need to setup like this Method thank you Man good
Cool glad it helped
Very interesting project and good vid!!!. I have to do something similar but because I live in the cold cold Edmonton I do not have the option of exhausting that volume of air outside the shop and have to recirculate it, so I will make a box and add a furnace prefilter and a couple of activated charcoal filters to the system. Would you know the CFM or liters per seconds the fan you used moves!? Thanks a lot for sharing and good luck!!!!
I have the fan and other parts listed in the description, this particular fan is 1450 cfm. Good luck on your project! :)
Wow, what an idea it paid fair good
It has done wonders for my shop
Nice work
thank you :)
Like your plan for the knockouts😉
Thanks!
Good job
Thank you very much
Cool video man
Thanks Tim
I already have about 80% of what you used in the video sitting on my basement floor to make something similar. I’m sort of glad I put this off. You have two ideas that I hadn’t exactly worked out. Or really had a different idea. The pivoting bracket and rigid tube. I have a 10x16 space to weld in and if I am MiG welding it will fill up with smoke if I don’t have a fan going and open doors. It’s 30 degrees right now. Guess what I don’t want open? Guess this will need to become a priority. How many CFMs is your fan? I have a few laying around that I think will work, but the only way to really know i suppose is to hook them up.
The fan is a 1450 cfm attic fan. I was worried at first that it wouldn't be strong enough but I haven't had any issues with it doing it's job. And brrrrr that's way too cold for this desert rat for sure :)
Artfully Rogue haha. When I took temps on the wall around my Uncles house last June of 170°F I realized the desert was a little hotter than I remember. 🤣 I’ll have to see why the CFMs are on the fans I have.
Thanks for the video. I am trying to do a similar system in my garage 🤪. What you would do different?
I would want more flexibility with the intake vent. Right now it only covers my welding at one end of my table. I need to modify it so I can move it around the whole table
You saved thousands.
Yep and it works great for what I'm doing
Thanks for this update.
I did a dust extraction using a Centrifugal fan but the fan pressure was too low to absorb the powder dust. can I use an Inline fan to enhance the system performance? kindly reply me
This is really great. Thanks for your brilliant efforts. I am thinking of using industrial pedestal fan by connecting it to 3 inch diameter PVC pipe behind. Will it work?
I'm sure it will pull some air, not sure how much though
Like the concept 👍
Thanks Gib. And good talking with you the other night on IG.
@@ArtfullyRogue same here!
Nice Build -- during your test, was that MiG fluxcore?
I have a small garage so I would put a switch near the draw in end so I am not sucking all the out all the heat in the winter.
Cheers
Yes I was using mig flux core. Good idea to put the switch close.
Rather genius! Way above my DIY abilities, but helpful nonetheless!
Nice job! I would have save the thermostat though - could have wired it up for remote on/off so it's not constantly running.
this is great video, thank you for clearly explaining each step
Glad it was helpful! thanks for checking it out!
Great idea! What do you think about turning your "funnel" extractor around, end for end? Meaning, put the larger end near your workbench and the smaller end out the door? Of course, you'd want to change the fan's direction of rotation. Just a thought.
It is ment to suck the smoke, if you do that it take away alot of air within
Excellent
Thank you! Cheers!
I love brush-less computer fans for silence and 1000% efficiency compared to induction motors. You must use squirrel cage fans for the pressure needed in ducts and use more than one in parallel because cheap big fans can't be bought.
Yeah this fan works in crunch but could use some improvements
So legit. Def go to solid steel. Tuck it around perimeter of shop. Absolutley perfect size fan, power, diameter as well as the whole way through the job
Its worked well for me
Thanks for the video, Nicely done.
I notice you use gasless mig, Never used it. Do you have a video on it?
I don't have a video on it and it's easy to use but after almost 20yrs on this box I might be going to a gas set up soon, just cleaner and less splatter
@@ArtfullyRogue Thanks
With this you can also do KBbq at home.
Great video! Just wanna ask, Are this type of extractor allowed in restaurant kitchens?
Would you add any filters at some point? If the door had to be closed it would be great to be able to continue working
I think the only time I close the door is when its pouring rain which not very often here in Arizona but adding a filter would work great!
Sir I need your help. Recently changed my roof at home and the heat is getting trapped inside which is now making the living space unbearable from the heat. Can I use that system you made to extract the heat from above the ceiling ? Please teach me
I like the 4K
Thanx bro
Thanks for the info :)
No problem! My pleasure, thanks for watching
Very nice
thank you very much
My pleasure 👍
I would like to have a similar system but it would have to extract the smoke to the exterior through a concrete wall. Any advice on how to do that?
My first thought would be to cut a hole in the concrete, unless you have a window that you can make an adaptor for and direct the fumes out the window or through the hole in the concrete
Just a suggestion for stick welding, not for TIG or MIG. How about using a normal cooling fan like you use in your living room on a hot day? Obviously it would be unsuitable to have even slight breeze / wind during TIG or MIG welding. So place this domestic fan to one side of the welding operator, creating a kind of slight wind tunnel effect so that any fumes are blown away from the operator and in the direction of the diy extractor, which could be maybe 1 or 2 feet away to the other side of the operator? Would that help to prevent any stray fumes possibly being inhaled?
Sure seems like that would work
I am about to put an exhaust fan together for a welding exhaust hood. I have a 5" metal duct in place. Would it make more sense to find a 5" fan or use reducers to take an 8" fan down to 5"?
I found that reducing the diameter does restrict the flow a bit. Finding a 5" fan may work better with a 5" duct
@@ArtfullyRogue that is my thinking also.
Good job on your extractor. May I suggest you edit out the few seconds using a cutoff grinder with no guard which is a bad example especially for newbies to grinders. Weld.com's channel has a video on grinder safety and at 43 minutes shows results of using no guard. Please. Thanks. Search video: Grinder Safety | How to Properly Use an Angle Grinder + GRINDER FAILS
Thanks Johnny, yeah I've been trying to figure out how to edit the video after it has been published without completely removing the video. Still working on that.
well played sir
Why thank John
How we could select the corresponding diameter of the duct in considering of the fume, for instance I am working in welding area and there are different types of welding. Expected clean air and duct design? is their any standards?
great idea! just wondering why you run flux core instead of using cover gas.
I've used flux core for over 20 years in the same machine. I always said that when this little box dies, I'll buy the tank and a new mig machine...it's still going strong. The majority of my work is rustic and industrial style so the splatter kind of adds to the character of the projects. For the cleaner neater projects I'll use my tig machine
