Soldering Exhaust Fan




Introduction: Soldering Exhaust Fan

This is a project we did in our Robotics class. We realized that in our future projects, there would be a lot of soldering involved. So, we decided to make an exhaust fan for filtering smoke from soldering. In this fan, we used an old laptop fan and modified it as needed. Now, YOU CAN MAKE ONE TOO!!!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials

Here is a list of materials that will be needed:

-Laptop exhaust fan
-carbon filter
-solder gun with solder wire (lead free if possible)
-hot glue gun (glue that fits your gun)
-Hand saw
-skill saw
-safety glasses
-straight edge
-drill bits

You will need a place to work and make sure you have all materials before you start.

Step 2: Disassemble

Start by disassembling your laptop exhaust fan, first by taking out the screws and pulling both sides apart (but not too hard.)
Then after you have both sides apart, you'll want to take out both fans (one if that is all you have.)
When this is done you will want to start cutting.

When cutting you will want to take off two sides, this is for the wall later on.
Make sure both sides are of the same width and length, so later on you can re-attach them with ease.
When both sides are cut make sure to file them down so there are no rough edges.

Step 3: Glue Together

Next you will want to glue all four sides (top, bottom, left, and right) to the back piece.
We used a hot glue gun, because it was fast and easy.
When you are done gluing, make sure to let it all dry before putting the fans back in.

Step 4: Attaching Pieces

When the glue is done drying, you will want to put the fans and switch back into the case you just made.
When done with that, plug in the fans and check the direction that they are blowing; make sure the fans are pulling in the air.

Step 5: Putting in the Filter

Next you will want to put in your filter, it will go in the side that is open.
Make sure you cut the filter to the right size.
We made our filter a little thicker so it would hold itself in place.

Step 6: Finished Product

At last your project is done and you can start your soldering without the fear of having smoke in your face!
Thanks or checking out our very first instructable, and we wish you luck on your future projects.

    It is a cut to fit carbon filter for an air purifier. We ordered the wrong size by accident, so we used two pieces. A little better planning and you could just use one.

    I have just one question. What tape of foam filter is that?
