Thanks for sharing your experience with the production fume extractor. I'm remodeling my garage into a shoe repair shop, and many of the glues and solvents contain VOC's. I've been reluctant to spend $2k-$3K on a production fume extractor, even with a charcoal filter; I would prefer to vent everything to the exterior and let Al Gore worry about the atmosphere...lol. Anyway, addressing the negative pressure with the louvers from the exterior was a great piece of info, as that was a concern also. I spent a full week in Cleveland learning nothing but stick at Lincoln Electric; that bracket will be a nice beginner project. Thanks again.
Fantastik Great Job from one welder to another... I just happen to have 2 old 220 volt furnace fans so i'm going to build one of thoes... Thanks again good buddy.. L.T. Dan cwi
This isn't L. T. Dan from South Carolina is it? Surely not... But how many L. T. Dan's can there be? Well, I do know one that lost his legs in Nam... 🤣
@@thomaslove6494 Nope but I was dubbed with that name back in the summer of 94 the day after the movie came out and it Stuck..Funny thing is my working partner got dangled in by default and he was the Perfect... You guessed it Forrest Forrest Gump and is still called that to this day...
Hey! That is a nice setup... I actually have a squirrel cage blower on the way to my house right now I plan on using to extract fumes from my garage.... I was thinking of running some ductwork over to my welding table and building a hood over the table to suck the fumes right up off the table. Does this method keep the shop clear of smoke while you were welding? If so I need to think about just doing this it would be much easier.
Hey I like your idea about running duct work to the table. This method would work much better. My extractor takes about five minutes to clear my shop, but it doesn't suck up the fumes at the source.
Simple enough. If you block off some of the inlet then it will run more efficiently and actually pull more air. Those fans are designed to pull air through ductwork and are made to work against that resistance.
@@RCWeldingsgarage You will see an instant change in the tone and suction of the blower. You can put an amp gauge on it to set the peak flow - block it off until it draws it's rated amperage.
Just asking cause I have a furnace fan (with an exterior mounted electric motor). Just searching around here for ideas. I got the exterior mounted motor so it would be separate from any combustible fumes being drawn out through the cage. Does your unit have the motor inside and are you concerned with fumes that could combust, or not? Thanks.
No I'm not too concerned as I don't paint in my shop anymore. The only thing I use it for is welding fumes and humidity in the shop. I was looking for your style furnace fan with the motor mounted on the outside but I couldn't find one. Hang onto that setup it's the best for exhausting fumes and paint.
@@RCWeldingsgarage Thanks for the reply. Helps to confirm I am going in the right direction then. I like how you built that plenum box to vent outside. It allows you to have your unit turned. That would work great with mine too. Do you think the change in direction (not blowing straight out) would impair the airflow somewhat? Again, just looking for your experiences so far as it means a lot more than theory. Be safe. :)
@@dginta7932 My buddy built the box for me. He owns a hvac company. I can clear my shop of fumes in about ten minutes of it running. So I think it's OK the way it's setup. He used the same setupin our friends mechanic shop to clear car fumes using a furnace fan/blower like yours. They capped one side off and used the other to connect to large diameter pvc pipe and from there they branched it off to hoses running down to the cars exhaust to suck up the fumes. Works amazing.
The box was built to accommodate the square opening of the furnace exhaust end. You don't need to build a box like we did but you will need to enclose the end that vents out.
Thanks for watching. The box was made to fit the opening of the exhaust fan and to collect the dust and push it of the wall. You can design one anyway you like, even with an inline wall fan. This setup works well in my shop.
OK cool! I wasn’t sure if the box was required to provide back pressure to the fan as they are normally installed in a furnace with plenty of back pressure?
@@m.m.m.c.a.k.e my buddy who is a hvac installer designed it. I don't think there's any back pressure. I've seen him install a few at my other buddies shops and they all have different configurations without a box. However I could be wrong and it's possible that there's some back pressure. But honestly any setup with a good exhaust fan or furnace fan should work. My old shop I used to work out of, I would put the furnace blower at the door of the shop and it would just push all the smoke outside in minutes.

Good practice to have the intake air as far away from the exhaust as possible, maybe on different wall or at a much lower level than the exhaust.
Great idea.. Glad you posted this .. I'm going to do the exact same thing ..
Awesome 👌 . You won't be disappointed. I use mine every time I weld.

Thank you very much!' I'm glad that I can help out another fellow welder.

Interesting. Ty for letting me know. I may try it and time it to see how long it takes. Maybe I'll make a video and post it on TH-cam.

I was mistaken, it is the outlet you want to restrict. Sorry, been a while since I messed with mine.

What's the purpose of the box ? Just curious I have a furnace fan I was wanting too do this
The box was built to accommodate the square opening of the furnace exhaust end. You don't need to build a box like we did but you will need to enclose the end that vents out.
Thanks for the video. What is the box for? Can you just mount the fan to the wall and then out?

What gauge is that metal?
I don't know the exact gauge. It's the same material used in homes. It's not the thick. Maybe just under a 1/16
Can i get your number? I wanna make a exhaust system in a welding school i have! I have 23 booths! I need help
