Step-by-Step Instructions (18 Steps)
Compound Value Type Disassembly FlowStep 1
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.
Step 2
Position the fan over the box so that an exhaust cutout can be made.
Step 3
Use a pointy object like a screwdriver to poke four fan mounting holes into the box.
Step 4
Use a pen or pencil to mark the inside diameter of the fan onto the box.
Step 5
Use a razor blade to cut out the fan exhaust port.
Step 6
Poke four more holes about 1 cm out from the ones you made earlier.
Step 7
Flip the box over. Use a pen or a pencil and a straight edge to mark out the intake port. Leave a lip so the filter material won't fall out when placed inside the box.
Step 8
Use a razor blade to cut out the intake port in the box.
Step 9
Thread four zip ties through the fan mounting holes.
Step 10
Activated carbon filters come in all shapes and sizes. You may need to cut and modify the filter to fit your enclosure. Cut the filter so it will fit snugly in the intake port.
Step 11
Insert the filter into the intake port. If your filter doesn't span the intake port, you can use glue or tape to connect multiple filter sections together.
Step 12
Thread the zip ties through the fan's mounting holes. Make sure the fan's intake side is placed against the box hole, or you'll end up with a soldering fume blower. Secure the fan to the exhaust port by tightening the zip ties. Clip the excess zip tie strap.
Step 13
Note and remember the power and ground pins ↗ on the fan connector. Cut off the fan connector.
Step 14
Use a pointy object like a screwdriver to poke a hole in the box for the fan cable. Thread the fan cable into the box.
Step 15
Use a pen or pencil to mark the outline of the switch. Choose a convenient and easily accessible location. Cut out a hole for the switch. Pull the fan cable through the switch hole.
Step 16
Before soldering, make sure the fan is wired up correctly. If the positive and negative wires are switched, the fan might burn out. Solder the switch between the fan's positive wire and the battery's positive wire. Solder the negative fan wire to the negative battery wire. Pull the excess cable back through and mount the switch to the box.
Step 17
Place the loose wires in the box. Secure the 9V battery to the interior of the box using double sided tape.
Step 18
Rejoice! The days of holding your breath or inhaling solder fumes are over. If your solder fumes are especially potent and are visible in the exhaust, you can stack additional filter material to trap them.
