Solder Fume Extractor

After pricing out and reading reviews for a few different solder fume extractors, I decided to try and just build my own.


  1. Cut the end off the power supply.
  2. Strip about 3/8" of insulation off the wires of the power supply and cooling fan.
  3. Tin the tips of each wire.
  4. Slide 1" pieces of shrink tubing onto the wires of the cooling fan.
  5. If the power supply has a wire with a stripe on it, solder it to the cooling fan's black wire.
  6. Solder the remaining wire to the soldering fan's red wire.
  7. Slide the shrink tubing over the soldering joints and apply heat.
  8. Cut a piece of carbon filter 1/2" wider and 1/4" taller than the cooling fan.
  9. Place the carbon filter between the cooling fan and the frame so that 1/4" sticks out on each side and the top (you want the bottom to be flush so that it sits flat and stable on a table). Then use something sharp to poke holes through the carbon filter for the bolts.
  10. Run the 3" bolts through the bottom of the frame, carbon filter, and cooling fan. The longer bolts will help stabilize the cooling fan.
  11. Run the 2" bolts through the top of the frame, carbon filter, and cooling fan.
  12. Use the lock nuts to fasten everything together. Do not over tighten. Just screw them on enough to hold everything together loosely (you don't want to crush the carbon filter).
