Introduction: DIY PVC Solder Fume Extractor

I make a solder fume extractor using PVC plastic

Step 1: Cutting 3mm PVC Plastic Sheets

I begin by cutting 3mm thick PVC plastic sheets into the proper dimensions to make the box. The front panel will have a circle opening for the air to be pulled in.

Step 2: Front Panel With Circle Cutout

I cut this piece after measuring it with a compass. The back panel has a octagonal opening which will allow me to attach the fan to the back.

Step 3: Drilling Holes to Hold the Fan

With the front panel cut, I dry fit the fan. I then drill the holes for the fan on the back panel. Once the fan was temporarily screwed in, I marked and cut out the hole for the power connector.

Step 4: Soldering the on / Off Fan Speed Potentiometer

For this project, I used a potentiometer that has an integrated on off switch. I soldered it to the power connector and dried fit the potentiometer to the front panel

Step 5: Gluing the Side and Top Walls of the Enclosure

The side walls were then glued to the front panel. And then I glued the top and bottom walls. I drilled the hole for the potentiometer and the status LED on the front panel.

Step 6: Soldering the Control Electronics and Fitting the Potentiometer to the Front Panel

I soldered the electronics which will run the fan speed and the LED. Afterwards, I drilled some holes on the back panel which will allow me to screw it to the front assembly.

Step 7: Final Assembly and Fitting the Activated Carbon Filter

As before, I glued some velcro strips to the front panel and stuck on an activated carbon filter pad. I then began the final assembly by fitting the electronics and attaching the fan.

I used hot glue to stick everything in place. Finally, I tested the fume extractor as before by melting some solder flux.

Step 8: Testing the Fume Extractor

The unit works fine however the simpler cardboard unit seems to be more powerful. Maybe because of the larger space between the fan and the filter.

    Thanks for watching. It turned out ok, but the one I made out of cardboard performed better. And it was much easier to make.
