Introduction: DIY Portable Fume Extractor
At the workplace, we often need to etch some circuits and for those of you who have tried it, you know how important to do it in a properly ventilated space, if not outside. That wasn't really an option for us so Paul Strohmeier and myself decided to build an inexpensive portable fume extractor.
You will need:
1x Under the bed storage bin with hinges (or similar) (link)
2x 120mm fans
2x 92mm fans
1x 20ft 4" duct (link)
4x metal duct to duct connector (link)
1xATX Psu (or some other source capable of powering the fans)
This is just an example list, by no means you need to stick to it
Putting everything together:
1- Drill 2 holes in one of the side of the lid (refer here for approximate dimensions)
2 - Attach the 2 120mm fans on the inside of the bin (make sure the frame is facing up)
3 - Glue 2x metal duct to duct connector around the fan holes.
4 - cut the duct in half and attach each half to a metal duct connector
5 - repeat the process for the end of the duct
6 (alternative) - because we had a pre-drilled wall with 92mm fans we connected the ducts there so we have 4 fans blowing air outside. You may want to use just the 2x 120mm blowing out the window. Should suffice for most applications!
Images should be self explanatory!
Hope this helps and have fun etching
We have a be nice policy.
