Reverse airflow on aquarium air pump

Aquarium airpumpI recently bought an aquarium pump (this one http://bit.ly/mGSbB5) from dealextreme. It’s a 3w airpump with rubber feet, and nice plastic casing. So I hacked it to reverse the airflow so it would suck air rather than blow. This is due to that I need it to suck away fumes/smoke when soldering. It took me little time to figure out how such a thing worked, and so I hacked it. Not a problem when using hot glue.

It reversed the airflow, but not enough. I had to have the soldering iron just beneath the plastic hose before I could see any effects. So I upgraded it, I drilled some larger holes where the air could flow through, also some holes in the casing itself to make sure the air inside could get out. But with no major luck I still needed to put the hose just above the soldering iron. The smoke didn’t even change direction when the hose was 1 cm away.

Ok the hose is around 5 Meters in length. I’ll go to the pet shop tomorrow and get me another hose that I can cut and adjust as I see fit. The hose I’m using now is meant for water cooling in a PC.

Else I think I’ll need something that can move some air. I don’t think the 5W airpump that DX also have will make any difference.
