This is a re-publish of a poorly done instructable that I posted a while back.

Transform an aquarium air pump to create a weak vacuum

This type of pump will only produce a weak vacuum but I use it for positioning electronic components and de-soldering applications.

You will need a tetra whisper Aquarium pump, a Philips screwdriver and about 5 minutes.

Step 1: Open the pump

On the bottom of the pump you will fins 4 Philips screws. Remove these with a number 2 Phillips driver.

Flip the pump over and lift off the large blue plastic cover.
Nice instructable! How much vacuum does it generate (PSI or Hg)? I saw the gauge but it's not clear what the reading is.
<p>9 in Hg Vaccum. its Psi for the blue and Hg for the green</p>
<p>in Hg. Inches of Mercury.</p>
i think it sais psi on the bottom right of the blue part
<p>Trying to find a cheap way to create a vacuum so I can attempt the wine bottle electron accelerator instructable... Do you suppose this would be sufficient enough to create the vacuum in the bottle required to perform the experiment??</p>
<p>I noticed that the Tetra pump has not changed (internally) in over 25 years. I used to repair them for my customers (pet store). As for the instructable - very well done. Looks very easy to do. It is a practical tool for light duty. I wonder if it can be used to vacuum seal food bags.</p>
Great Instructable! This was a big help. <br>
The green part of the gauge is scaled differently and appears to be in inches of mercury and looks to be reading 8&quot;. That corresponds to -3.9 PSI or -27 kPa. <br> <br>That's quite an OK vacuum for picking up electronic components. <br> <br>I'd like to know if it is good for desoldering too and if it is then all that is needed is a filter to stop the solder particles from reaching the pump.
