Soldering Fume Extractor

Fume extractor housing for a PC fan, great for soldering. Includes designs for both 120mm and 140mm fans. Works for both 3-pin and 4-pin fans, just connect the 12V and ground pins. The speed-sense and PWM control pins do not need to be connected.

I recommend using at least a 2000rpm fan to get adequate pull. I am using a 140mm Noctua NF-A14 iPPC-3000 PWM and it works well from 8-12 inches (20-30cm) away.

Required hardware:
(1) 120mm or 140mm fan
(8) PC fan screws
(1) 12VDC power adapter
(1) DC barrel jack - panel hole 8mm diameter
(1) Power switch - panel hole 12mm x 18.7mm
(1) 3-pin or 4-pin fan connector
Wire and soldering tools
(Optional) Heat shrink tubing
(Optional) Carbon filter

Wiring Instructions:

1. Connect the fan power pin to one of the switch terminals
2. Connect the other switch terminal to the DC jack positive terminal
3. Connect the fan ground pin to the DC jack ground terminal
