Simple Soldering Fume Extractor

Introduction: Simple Soldering Fume Extractor

Hello ! In almost all professional electronics environments you will find some form of a soldering fume extractor. This may be a simple desktop unit or it maybe built into the builds ventilation system. The purpose of it is to remove the soldering dust and flux fumes from the work so you don't breath them in. You can buy them from many vendors, most look almost like a little black box that can be tilted, has a filter in front, a fan, and fins on the back to move the air up and away from you. I made one a few years ago with some hot glue, cardboard box, zip tires, old server fan, a real fume extractor filter and a 12v wall plug. The main problem was the box would get caught in the fan and it would fall over, also a 12v wall plug takes up space on your power strip. Now that I have access to all of this fancy equipment I though I would make one from spare parts and make it look cool.

Step 1: Design !

Well I started with the stuff i had laying around. I have a old Rotron Muffin (Date stamped 1988 !) 120 x 38mm 120v AC fan, some left over fan filter assembly's from allied electronics, and some 1/4in plywood. I made it in CorelDraw, and will attach the files for the laser. I have changd the files from the original because I did not put enough fin's in and made them a little to lose however some wood glue will fix that right up :)

Step 2: Laser Time !!

I was very excited to find out that i got my settings correct to cut the wood on the first shot, which never happens to me ! but forgot to level the piece so I had to re-cut the right side.

Step 3: Build and Assemble !

Now I made the tolerance's fairly tight on a few parts to hold it together without glue or screws !, however if your plywood, or acrylic is not thick enough once you have the fan screwed in it will hold it together. I was really upset at myself because when I installed my fan i pushed in on the back pushing in the bearing and ruining the fan :(. I put a simple whole in the side to run the cord out of. Hope you enjoyed this, I threw it together pretty quick, so its not perfect.

    as with all of these Solder Fume Remover-extractor-eliminator-every other dissapearing word availible- that come about on Instructables this is no exception. This would not remove the soldering fumes but rather blow them abour in your room. there should be some type of Very very tightly woven filter gaurd to absorb fumes such as a sponge etc. this will only ensure the fumes get nicely dispersed in your bedroom so you can go to sleep and breathe in toxic un-condensed fumes and particles that even at a low scale can cause lung damage, OA and dematitis. Perhaps a pipe of sort attathed to the back and ran out a window would do the trick.

    Most of the commercial solder fume extractors use a charcoal impregnated filter to trap the VOCs as well as the particulates. I use activated charcoal granules held between two layers of foam cut to size window AC air filter media (if you buy charcoal granules, make sure you run the contents through a mesh strainer and throw away the fine dust, or you will have it ALL over the place!) Another option is to buy charcoal pads and air filter media from a company like Air Filter Factory (no association) and either cut them to size or buy a size that fits your fan design. It is possible to find some residential range hood filters with charcoal in them, but they are very expensive in comparison to other opetions.
