While looking through a box of old electronics, I found this: a motor from an old inflatable mattress. It has a plug directly to AC and a momentary
switch, and testing it found it to be extremely powerful, with air coming in through the front and exiting through the side. Does anyone have an idea
of how I might start to modify this to be a vacuum pump?

For a start, test it and see how high a water column it will pull.
Second, see if the motor capable of long runs without thermal overload? DFliyerz - 16-9-2015 at 20:01

I'm not planning to use it for long runs, probably just for filtering. I can't do a water column pull because I don't have the faintest clue how to
hook it up.Bert - 16-9-2015 at 20:14
Duct tape! A transparent plastic tube. A bucket of water. A stairway or ladder.
Seal the intake port to the plastic tube with duct tape. Put the other end of tube in water bucket. Get as much vertical separation as needed with
pump above bucket. Don't bother trying to get more than about 32', though.
Turn on the fan. Find height water column is pulled up to. Leave fan running as long as you'd expect to need it to for your filtration process. Fan
doesn't squat from overheat? Got enough vacuum to be useful? Good to go!
