Budget fume extractor

[Part-time]

I'm sure everyone has seen those fume extraction and ventilation systems for sale for anywhere between $1500-$5000 and up. Ventilation is a must, but spending that kind of money seems ridiculous. This is a simple design I came up with using 8 inch duct work, a 735 CFM greenhouse fan, an outside vent fixture, and an adjustable mount that can hang on my shops rafter ties. I tested it out running a couple of 6011 rods at 125 amps and sure enough it sucked the smoke right out. Total cost: $200

my fume extractor...

I'd recommend some metal at the inlet for at least a couple feet to minimize the risk of sparks catching your flex duct on fire. It can also give you some solid to help position it if you make it moveable somehow. I see you also have a fire extinguisher there, so good on you! Looks like a good setup.

Looks great
Myself I do all welding outside just let the wind blow.

Looks good
Be careful in the winter
It will suck the heat out of the room in no time flat.

Thanks guys, I appreciate the feed back. I was planning on putting a hood on this but I was having a hard time designing one that didn't get in my way. The head swivels on the drop tube via the bolt that mounts it (forgot to mention the 6 to 8 inch stove adapter I used for the duct to clamp onto)
Stay safe all

Great ideas.

I just ordered an optrel swiss air PAPR to wear because my setup isn’t conducive to fume extraction like this. $1300 hit.

Just work outside and let the wind bow the smoke away.
It is FREE and no building cost too.

You really need to step away from the keyboard for a while.

Your reply here is just completely stupid.

The original poster seems to have a nice work area and just wants to dispose of the fumes.

But I see that you are replying to Brooklyn’s bravest
Who has a pretty nice small shop of his own and also as a business owner.

Not everyone is going to set up camp in the driveway to do a welding project or weld multiple pieces for production work.

You really need a hobby, dude.

You reply to nearly every single post with a lot of times some very objectionable advice.

It’s getting old.

My welding shop outside in field . My machine shop was indoors.

It is very common to see a welding/fab shop outside with small building for machine tools only
In Fresno California. It cuts the overhead down.

Dave

PS If you wonder how you in rain 🌧 simple save work that can be done in the machine shop last or when rains 🌧.

I used umbrellas 🌂 for rain 🌧 too.
Not used in the summer
The welding table was under a awning still outside.

Working outside isn't really a possibility in the New York City region. I outsource 75% of my work now fortunately due to volume requirements and my own time constraints however my very small space is definitely at capacity. My actual land is 40x100 and my neighbor is about 10 feet away.

The exhaust from the garage does a nice job building up iron on my truck that has to be regularly removed with expensive automotive iron remover.

It's just not quite farm country....


I'm considering buying a building for my business to operate out of, but to the tune of 7 figures while I currently have no real overhead its a tough decision.

[smithdoor]

Sounds like warm building too.
Today I am retired but when shop I had 5 acres every thing I did was big.
In California it sunny 🌞 most year.

Let me know how comfortable that system is. I am interested in it for confined space items

Good plan. $1300 won't even cover your first night in the hospital with a respiratory related illness

Did you buy one buy for the mice and bugs.

For summer you setup air duck from the evaporate cooler.
I use a small evaporate cooler when welding outdoors in 110° F days. It like sea breeze while welding.
Note I pointed air on me not the weld.

Air Duck

[smithdoor]

Maybe
Keeping the overhead down and living where on good year we 10" of rain 🌧.

But start work in high school and then college as a iron worker. FYI iron work paid for college no loan or GI loan. Wall of college paid for.

Air Duck

You on your welding on the other thread was excellent 👌.

Would post earlier but was tie-up.

Couldn't help myself. I like to take the pizz whenever I can, it's a character flaw.
