    • This fume extractor is composed of three main parts: a 12V computer fan, cardboard box enclosure, and activated carbon filter.

    • Solder often contains rosin flux. When vaporized during soldering, it's a respiratory and eye irritant and can cause health issues when inhaled long term.

    • This extractor pulls the harmful fumes into the charcoal filter trapping volatile compounds, removing them from the air.

Nice job. As for those 9 volt batteries, you will find that when your smoke alarm starts beeping, the batteries still have plenty of life left for running the fan. No need to buy a new battery.

how long will the battery last? why not use a battery connector? so changing out the battery would be a lot easier.
