Solder Fume Extractor From Old Hair Dryer

Keeps my lungs from filling with solder fumes

 

I have made a couple of solder fume extractors using Altoids tins. You can find instructions for these on the Internet. However, I always found that I had to get the extractor very close to the soldering, and this was not always easy to do.

The other day I was clearing out my workbench, and I found an old hair dryer saved from another project. It struck me that with this, I could make something that was much easier to position close to the source of the solder fumes. 

It turned out to be very simple. I think the video explains it well. Here are the parts, materials and tools I used.
Easy.

Great idea, and a nicely done video too. I'll have to make one of these if I can find all the parts. Just one question; couldn't it be plugged into the mains supply instead of batteries? It could get to be a pain when you have to recharge it constantly.

Yep, I bet that would work great!

Just jank out all the heating coils and add a filter and a base to hold it standing. Make sure you leave in the diodes, since it is a DC motor and the diodes form a rectifier circuit to change the AC to DC. 

If you build one, post the results!

You will have to keep the diodes (rectifier circuit),
but I think that you have to reverse them.
After all you need the motor not to blow, but to suck air.

basile

Ha ha, good point!

You are right, of course. You will need to desolder all four diodes and reverse them.

Ig, your hack is awesome but I have a question, can't a similar setup be make using a computer fan and a tube? It also serves the purpose of removing toxic fumes (although it will be less effective).

thats what i did... noodle box as tube, 12v 'puter van powered by 4 rechargeable AA's and the obligatory fish tank foam as a filter one thing i did notice tho... it lacks immediate suction so a more powerfull fan might be better (also making sure there are no side leaks is very important too - i used elastic bands across the foam to make sure there where no leaks) dom

Sure, you could give that a try.

The fume extractors I've built in the past (see Tinman and Lemonhead) were based on the Altoids tin instructions by Kip Kay back when he did Weekend Project videos for MAKE Magazine. 

The problem I found with these fume extractors is the same problem you'll probably have with a computer fan and a tube. The air flow is not as strong as a commercial fume extractor. It is challenging to position the extractor close enough to the work to capture the fumes. 

With this design, I can move the extractor where I want to; I can adjust the height of the input port by angling the head of the hair dryer.

Great walkthough ig - a really useful hack that doesn't require much effort to put together.

Every bench should have one!

would be a good showcase for this hack?
