- EASY DIY Welding Workshop Ventilation Fume Extractor Done CHEAP. With cold weather approaching, many of us are having to work inside which means we need to keep the warm air inside our workshop and the smoke and fumes outside. This week I am going to show you how I built an easy DIY workshop ventilation system for around $60 bucks using common dryer vent and an inline duct blower. Now I can weld inside without having to keep the doors open and letting in cold air and now I can also run my motorcycles inside and service all the lawn and garden equipment without fear of Carbon Monoxide poisoning.

I'm putting together my own little welding setup in my garage right now, and this video is exactly what I was hoping to find! You just made my life easier and helped me save a bunch of money. Thanks bro!
Thanks man I appreciate it! Glad I could help!
Great idea and build Brandon. One item if you haven't thought about yet. Please add a Co2 alarm to monitor your work area. Cheap safety to insure you don't get poisoned from fumes. We love your videos and don't want an accident.
Thanks for sharing.
Excellent point Joe. I actually have smoke, fire and Co2 in the shop. I will have to mention this in an upcoming episode. Thank you for this brother. We all got to look out for each other 👍👊
Great idea.
There are a lot of great welders. Very few old great welders. The fumes will get ya for sure. Im going shopping in the morning .going to.build me one for sure.
Thanks again !!!!!
Thanks man! Good luck and enjoy your new clean air workshop :)
Great idea for extraction. I’m going to copy your idea to extract smoke that is generated from my dual laser cutters engravers in my garage. Wow! I like your lift/table! Thanks for sharing.
Thanks Don! This table works great and I love that my workshop doesn't have to be smokey anymore! Good luck on your project and thanks for commenting :)
I had a blow up bouncy castle for my daughter and the blower I converted to use it as a fume extractor, boy does it suck fumes lol. Good idea you got there I would do this if I didn't have mine. Thanks for vid.
That's a great idea using a bouncy house blower...those things can move some air! Good thinking!
Exactly what I was looking for. Cheap solution to exactly what your doing. Thanks
No problem 👍
See you in action give me confidence that I too could start a channel. But I KNOW there is so much time into things that I the view cannot fathom the effort required. You do a great job at coming off a genuine and honest. Probably because you are. Nice work brother look forward to more definitely
Thanks man I appreciate your comment. Your right about the channel. It takes a ton of my time and doubles the time it takes to get each project done but i figure i might as well record it because I enjoy helping others and passing on tips and tricks makes it fun...
That will help, be safe ! Thanks for sharing with us.
Your welcome! Thanks for watching and commenting
Oddly your editing is really good. Love the flow, the extra info, and budget friendly is great. Will subscribe
Thanks Daniel I appreciate your kind word and support!! 🙏
Awesome video man! I was thinking almost just like that, great that it works!
Thanks! 👍
Excellent. Simple start but can be expanded on. Thinking metal hood with collar to attach flex to. OH! Plug it in to remote switch they sell for Christmas lites. Been using that for lights during basement remodel and works really well.
@Keith Marlowe thanks man and great idea on hood with collar. Since this video I actually have a 3 way remote attached to my welding table. One turns on the fume extractor and 2 others run fans that keep me cool during the summer :)
Thanks, ill be installing this over my welding table
It works pretty well!
excellent video.probably the best I've seen on RUclips. great visual,audio and presentation. I'll be rigging the ventilation system asap. thanks
Thanks Dave I appreciate the compliment!
@@BrandonLund I ordered my inline duct fan today lol. thanks again.
Sweet! 😁
Brandon, I couldn't help but notice the Yoshimura exhaust on the Kawasaki you had on the lift. Just a trivia, I had the opportunity to meet Pop's Yoshimura at his shop in Japan in the late 70's. In was in service and stationed in Japan near his shop. The "store" if you call it that was small and in the next room we met Pop's, standing at a workbench porting the head of a bike. This brings back great memories of my early biking days, and my time in Japan. Love your channel, keep it up.
Thank you very much! That sounds like a lot of good memories! 👍
Great work! Probably have half this stuff already laying around the house! Considering making one for welding. Holding your breath while welding galv isnt the best policy lol. Dont always feel like putting on the respirator. Hope you had an awesome thanksgiving as well :)
Thanks man! It's a really simple but effective way to keep your shop air quality a little better. Thanks for watching and I hope you and your family had a great thanksgiving also!
That's a good build , always safety first , I have some 4 inch flexible black corrugated plastic It comes in 100 ft coils maybe less I think I am going to try using some of it to do something like your build . Thanks. TANK
Using what you got...I love it! It should work just fine.
Great work.. I love your idea
Thanks Mark!
Great build!!! I managed to catch a local carwash going out of business and bought one of those big industrial shop vacs for $100 put it outside ran the hose inside to my welding corner of the garage and put an on off switch inside for it and it works great!!!
@Donal Thats an awesome idea and an even better score! Well done!
@@BrandonLund those thangs are actually tanks. I guess the coin mechanism is set to restrict some of the 2 motors power because after you strip all that junk out wire in an on off switch your left with two 5 HP motors. Plus replace the door seals with rtv gasket silicone and take the motors out put silicone around where they seal and bolt them back down.
No wonder they are so powerful! That's going to be an awesome setup!
@@BrandonLund it's been sat up for over a year now just sharing what I done to solve my little fume extractor
Oh gotcha. It sounds like a very good setup. You actually inspired me to keep my eyes peeled for one of those units.
Duct fan! That's perfect...I was way over complicating my plan. Thanks man!
Thanks man! Simple but effective :)
SWEET N SIMPLE!
Thanks Roger!
Great video. Thank you 👍🙏
Thanks Adam!
Awesome video brandon
Thanks man! Not a big fan of smoke and fumes so this helps and it was easy
I like it. I built a similar fume extractor a while ago.
Thanks man! It's a huge bonus in the shop!
looks easy and great .
Thanks man! It sure doesn't get much simpler and the benefits are huge when your not breathing in fumes.
Very Nice Work!!!!!!!!!!!!!!!!!!!!!!
Thanks for watching!
Amazing idea
Thank you very much!
Awesome, thank you
Thanks Ruben! 👍
Good simple build
Thanks man!
Hey Brandon. I know this is an old vid, but getting ideas for my own fume extraction for barn shop.One thing I discovered is that the higher volume of the cheap Harbor Freight inline fan works GREAT. Much better than the inside the duct fans. But while portable it's more clumsy. It's so easy to use those in the duct fans in a permanent application. You're the welder so I'm sure you already bought of this . . . you dint show us how it worked on weld fumes. For stick and flux core welding I place the flex duct right on the table. Pulls those fumes away easily. HOWVER, it's too much air flow for MIG & TIG (shielded gas) welding. Don't want to pull the shielding gas away fro the weld. For others watching I fabricated a way for it to hang over the weld about where your head would be. It allows the welding fumes and gas to to raise normally, but then suk them away before they get under you mask.
Nice! 👌
Good Idea man👌
Thanks man!
this is dope!
Thanks man!!
Nice Brandon. I have something similar made in my garage for both my car exhaust, and welding fumes.
But my I suggest that you do NOT have the duct sealed well against the exhaust. If you run your bike long enough, your whole pipe might become too hot and your duct fan would fail. Not only would the fan coil overheat, as it depends on the fan to cool it, but the fan blades are made of plastic, and they may melt. I suggest leaving a gap so the duct would draw in some ambient air to cool the intake down. That's how I've done it with my car exhaust extractor duct.
oh and btw, that sticky aluminum foil.... I'm not sure if you have the same kind I have, but mine looks exactly like that. We use it to wrap our diesel stove duct joints. It is heat resistant. I once even used it as a quick and cheap exhaust patch and worked great for years till I replaced my exhaust. Just a tip if you're interested.
Thanks for the videos!
Good point on not making a solid connection at the muffler...it makes sense. I know this stuff sticks like crazy but I was not aware it was heat resistant. It does not surprise me though because it just feels like quality. Thanks for the great comment :)
@@BrandonLund You're welcome. :-)
Great idea I’ve got a use for this in my shop. Maybe a couple of rare earth magnets glued to the end of the tube to hold it to the exhaust.
Great idea! The exhaust in this is aluminum but it could be very useful for holding near your project also
Brandon Lund shows what I know about motorcycle exhaust.
@@corydriver7634 this is aftermarket exhaust but a lot of motorcycle exhaust is made of steel so your idea was actually a good one :)
Yeah, I used to do all my work inside, but when I moved the Harley out of the loungeroom, SWMBO said, "NO MORE!!" So now all my work has to be done outside, subject to weather, lol. But being in drought, rain ain't a problem, but frying is, lol.
Still got 8 in the house and my project parts keep going walkabout thanks to 2 year old grandson.
And you used screws? This job's perfect for cable ties mate, lmao!!!
Mine would never even entertain the idea of having the bikes inside lol. My workshop never gets too hot but it does get a little chilly so the heater helps. Great idea on the zip ties...use what you got lol
Also dig the tunes 🤘🏻
Thanks man!
Aye good job man, look into how fire stations have there equipment. Maybe a local machine shop can make you a fitting thats universal and slides over different motorcycle exhaust ive got a small garage and the door leads right into the house tryna find a system when i work with carburetors or strong cleaners to vent it out and not make the family room reak of gas and solvent
Thats actually a really good idea Luke
awsome
Thank you!
I bought a bounce house blower from a guy for $20. I was going to put some of the semi rigid dryer duct on the in/ out to be able to place the suction end right at the source of the fumes. Set the output at the garage door to blow outside.
That sounds like an awesome setup! Probably much more powerful than than this setup. Those blowers move a ton of air!
Yeah. I've been trying to teach myself to weld with flux core, and it throws a ton of smoke. Last winter was a headache because the doors had to be open to exhaust the smoke. I ran across the blower after it started warming up, and that smoke was the first thing that crossed my mind. Just now getting around to thinking about the install with it getting cooler again. I was wondering if the semi-rigid duct would allow me to position it and it stay put. Thanks to your video, I believe it will.
I think it will also. Mine stays put pretty good. If it doesn't, you can use some metal wire to position it where you need it.
Have a pretty long run to the dryer vent in the building I'm using. Probably best if I use two inline duct fans, with one close to the fumes and another by the dryer vent?
I would be leary tieing it into an existing dryer vent because of lint catching fire.
@@BrandonLund, is just a hole in the wall, currently no tubes hooked to it. Goes directly from inside to outside.
Respect 🫡
Thank you!
i know this is a older video, but i like to mention that it's not recommended to place the aluminium duct on the exhaust that close, because the extractor will mess up your air/fuel ratio when you are doing air/fuel adjustments on a carburetor due the lowering of backpressure caused by the extractor. Best is to use a metal bucket with a bigger diameter then the duct pipe, and place that at least 5 centimeters from the exhaust tip.
Thanks for the info!
I'm planning on building a similar setup. I have to wonder how well the fan will hold up. I know it's just fumes. I wonder if it would damage the motor over time
It works pretty decent. It's not perfect but if it's directly over my weld it gets pretty much all the smoke out
That's a nice build. I'm looking for welding fume extractor options, wondering if a duct fan has enough pull to suck up fumes when hanging over the welding table?
Thanks! It works great but you need to keep it close to your work so it collects everything.
@@BrandonLund looks like you used a 4" duct fan and ductwork. Do you think I'd be fine with 4", or should I do it with 6"?
6 would be better i would think. The 4 actually works really well, you just have to make sure your duct is right above your work.
@@BrandonLund Thanks for your help!
Make a hood if need be.
How has this been working for you? I'm thinking of doing the same but I think ill go with 8 inch for some more airflow.
It works great. I'm very happy with it. I also use it for exhaust fumes. I need to fabricate a funnel intake and it would be about perfect.
Great work! .. question… do you think this will work to take out the fumes of fiberglass resine from my basement? I want to do some molds in winter time… thanks for your help…👍
It will but its painfully SLOW. I have sprayed paint and it takes forever so you would probably want a bigger unit that moves more air
@@BrandonLund ok… thanks I appreciate your response… I’ll take your advice… 🙏
Harbor Freight has I think an 8" air mover. That would probably be better suited for what you want to do
@@BrandonLund Hi… I’ll keep it in mind… make sense…thanks again 👍
are you planning on putting a filter into it to remove fumes or did i just miss hear you explain why you didn't?
No filter. It removes the fumes from the workshop by directly venting them outside.
4:12 exactly
I'm gonna do this for my generator, to pipe out the exhaust threw a dryer vent. Wonder how long the fan will last in there?
I'm not sure but mine is still going strong.
You believe your geny only pulls 100 sq ft per minute?
Is this sufficient for welding fumes? Its something I want to get into and I've been told galvanized steel in particular gives off really bad fumes
As long as the hose is above your work it will suck the welding fumes out.
@@BrandonLund I was amazed that little fan kept up with the bike exhaust. Does the fan list the CFM?
@C DRIVE at one time I knew the cfm but its been a while and its covered with duct tape. It's not very much but does surprisingly well. I'm thinking around 230cfm but I could be wrong.
What number of 3M respirator (2097,2096, 2011, 2291 , etc) would be fine for welding, let's say clean steel)? Respirator against titanium, manganese, nickel, chrome, gases or fumes etc?
This one here is used for welding:) amzn.to/3nCUm5O
Common exhaust pipe for hot water heaters
It sure is!
Snap lock Pittsburgh 👍🏻
For the win lol 🏁
@@BrandonLund you know how it’s 😂tinners are winners
I wonder if the fan is strong enough to pull the welding fumes out of the room? Maybe the next time you weld something you could comment on it. Thanks.
It is Richard. It's vented to the outside. If the intake is above your work it easily removes the fumes.
Lol you started the bike like Cheech and Chong, goes to your neighbors flowers?!
Nah, they know better than to plant stuff near the workshop lol 🤣🤣🤣
How about doing a video talking about the various types of welders that are available? The price range is $75 up to many thousands of dollars.
Great idea! Thank for the suggestion. I might just make this happen!
Nice job. I have to do something similar in my basement. I am wondering how to port the room though. I have a window that I don't really need and I can run the exhaust through there. Otherwise I could open the window, but that seems like trouble. It's a ridiculous window that opens like an oven door. I want to start mig welding in the basement with gas and this is the only way ;)
You could also install a dryer vent. That way you don't have to mess with the window.
@@BrandonLund Yeah, that would be ideal but then I need to put a hole in the house. Something to think about either way.
Did you do it? Im finishing basement with work shop on one end. Of course I hung ceiling drywall before thinking of this idea. Is your dryer in basement? Could y off and use that. Not sure if there is a duct check valve to ensure flow direction
I would try to keep the fume piping separated from any dryer piping in the event a spark got pushed into the dryer
Brandon - Do you think this would be sufficient to pump epoxy, spray paint, stain fumes up and out of basement window?
I use mine for spray paint but it has to be VERY close to where your spraying. It works but not great
Thank you
Nice 👍🏻👍🏻👍🏻👍🏻 i send you a movie on FB from what i make for welding fumes
Very cool man! That came out very nice!
can you post that FB link here? Great job on the budget exhaust extractor and easier than a range hood setup or agri fan.
@@AN-kg4ei used bathroom ventilation fans, I am using one that I replaced with another from my bathroom ( sounds like a bad bearing but just needs to be cleaned really well, dust makes the blades off balanced) look on the interwebs for a used one, they generally have a fairly high CFM. cheers!
Came here for ventilation done cheap. Now wanting to buy an expensive kick ass workbench.
I feel your pain brother! I can search the internet looking for a 20 dollar part and end up spending 500 on something completely different lol
I'll have to put a vent through a wall, I have no windows in my garage, but this could work well for me.
Sounds like this would be awesome in your shop! I love mine.
I had it built that way for better soundproofing, so I wouldn't piss off the neighbors as much using my anvil, I overlooked ventilation though, lol.
it's fin in the summer because I can have my double doors open which face away from all of them but Wisconsin winters make that less enjoyable.
Hot exhaust vapors might melt the plastic fan blade though
The metal pipe doesn't even get warm to the touch.
the tab on the tab is called a buddy tag : )
the tab on the tape sorry...lol
Good to know. Thank you 🙏
Sensible & practical, but, I’m thinking that duct fan may be too light duty for pulling weld fumes sufficiently…of course a higher volume duct fan will cost more….just my humble 2¢ worth.
@J W Dickinson it actually works pretty good when I remember to turn it on. The only issue I have is I need to add a bit more hose to the down pipe so it can be closer to my work. I had to move the horizontal pipe that is mounted to the ceiling because It was interfering with hitting my bikes when they go on the lift so it made the down pipe a little too short now.
100 sq ft per min is way too low volume; the suck must be powerful enough to draw air from a broad area, as locating the intake too close to the work will disrupt shielding gasses.
Brandon, I'm beginning to believe "OUCH!" moments like the one @11:00 are put there just to prove that we are not alone when those (!!XXX!!) moments happen. The east windows of my shop face my neighbor's Man Cave area in his back yard. So they get a steady diet of self deprecating, ranting expletives, like ... "Chris, you stupid dumb ass idiot! Why didn't you listen to that little voice?" I sometimes hear my Dad's voice from the grave saying *"STUNADA!"* ;-)
@C DRIVE hahahahaha PLENTY of those expletive's fly around my shop. Thankfully I'm decent at editing lol.
What do you mean by "dollars bucks" in your thumbnail image here?
I'm not sure
That metal duct will get hot enought to melt plastic parts
Not from my experience.
When I was in my twenties I was very careless about health concerns and safety. I really couldn't picture myself getting older, getting married, and having kids. I was living for the moment. I think that's pretty common actually - especially for guys. Then you start getting older and realize you need to take care of your body because it's the only one you've got! 😂 One thing I really took for granted was hearing loss. I have seen family members lose their hearing and it's actually really sad. Hearing aids can only do so much. It gets to the point where you have to shout everything at them and they still only hear half of it. It's frustrating for the people trying to talk to them and so people avoid talking with them. It's the sort of thing where you can feel alone surrounded by people.
Well said Christopher! I was just like most living for moment but as you pointed out, now I'm getting older and starting to realize we all have an expiration date so i try to do all i can to stay healthy.
Omg bro you got an old craftsman drill
Yes sir :)
I'm not sure you'd even need the duct fan if you're going to use this for exhaust for a bike.
@larrybud not so much for a 4 stroke but my 2 stroke needs it
I was trying to figure out what to do with an extra dust collector fan and tubing, I got more than enough for what I need, all I gotta worry about now is my wife texting me at 4am asking me where TF I am
Hahahahaha you and me both brother!
I am currently using a vacuum cleaner
Im sure anything is better than leaving it in the air to breathe.
In what sense does this have anything to do with welding?? Fan with plastic blades & exposed motor??
Absolutely nothing 🤣🤣🤣
Is that a can of tuna
It sure was! 👍
Dude, you can't blow air into or suck the air out of a closed room or container (try it with a beer bottle).
To move air through a closed room or container, you need an inlet and outlet. So, if your exhaust system really is moving air to the outside, you are putting the building under lower pressure than outside, and makeup air is seeping into the building from somewhere. This is usually through cracks in walls, and around windows and doors that penetrate the outside envelope of the building. If the envelope of your building were completely sealed, your exhaust system wouldn't work.
So you may in fact be drawing cold air into other parts of the building from outside more than normal while your exhaust system is running.
Anything that exhausts air from your building and dumps it outside causes this problem. This includes bathroom and kitchen exhaust fans, and anything that draws combustion air from inside the building like a clothes dryer, old or low-efficiency furnace, fireplace, etc. This is why a fireplace that draws combustion air from the house warms the room that it's in (with radiant heat), but makes other rooms in the house cold because the cold outside air is sucked into the outlying rooms through cracks in the building's outer envelope.
Rooms in a house with forced-air heating that don't have both supply and return ducts are usually uncomfortable when the door is closed. Such rooms can be cold in the winter and hot during the summer because the furnace can't blow air into or suck the air out of a closed room.
In any case, you aren't really "keeping the warm air in," since if your workshop stays warm, it's probably because your exhaust system is drawing warm air into the workshop form the rest of the house or building while making other areas cold. Still, it's healthier to run the exhaust fan than not.
The workshop was built in the 50's so its far from an air tight container and this fume extractor is far more energy efficient than opening up a 60 sq. ft door to ventilate the shop when it's 10 below outside.
Brandon, my point is, with respect to ventilation and energy efficiency, there is little difference between opening the door and the makeup air seeping in through leaky cracks throughout the rest of the building. However, when you open the door, you know where the makeup air is coming in and opening the door may eliminate or reduce uncontrolled makeup air getting sucked into other parts of the building.
If you are exhausting air from a building, makeup air is coming from somewhere or no air would be moving. In the summer, hot humid makeup air is coming in and in the winter, cold dry makeup air is coming thru the building envelope into the negatively pressurized building.
In a leaky building, the unconditioned makeup air may be seeping into rooms or living spaces that you would rather not have the unconditioned makeup air leaking into and moving through.
This is a common problem in restaurants that have big exhaust fans in the kitchen if they don’t have a makeup air system specifically designed to address the problem. The restaurant is under negative pressure, so patrons sitting near the front doors get blasted with outside air when the door is opened.
If there are any negative impacts from your DIY exhaust system, you can minimize them by only running the exhaust system when you need it. Thanks!
@Dee jay Thank you! P.S. ill have a beer with ya and we won't talk about HVAC but we will have a good laugh about all the money we saved by not hiring an engineer to design our 60 dollar extraction setup that works and! Oh, and the beers are on me! Thanks for the chuckle buddy.
@Dee Jay Yep, you guys pegged me. I studied civil, mechanical, electrical, environmental, and geotechnical engineering, I’m a PE practicing four of those disciplines in four states, and I have have 40 plus years of engineering experience. However, my first “career” was heating, A/C, and ventilation where I learned how to estimate, design and install commercial and residential heating, air conditioning, and ventilation systems, make duct work, do plumbing, and electrical work, a little welding, and to sweep the floors of my dad’s shop.
I never acquired a taste or need for beer, alcohol, etc. to have fun with friends at parties who don’t seem to mind. I’m frequently the designated driver.
In any case, others may realize my posts were factual not negative, and some may find them informative.
Don't get me wrong Earth Man, I appreciate your comment and you are far more knowledgeable than most about this type of thing, but for the folks that are watching this channel, most are just starting out, let alone hire a mechanical contractor to design them an evacuation system. I believe your intentions were well placed but probably a little too far advanced and technical for most of the folks on this channel. It might not be the perfect setup according to your training, but my goal in my shop was to remove welding fumes without it costing much, and for about 60 bucks it does. Sure it has to be pulling in outside air from somewhere but my house is like most, its not a perfect envelope. If I can help someone have less toxic fumes in their environment I consider that a win (even if its not perfectly optimized).
Its called aluminum duct tape.
👍
You lost me at the 100 SQFTPM blower.
Thats ok. It works for my needs and thats what matters
