I am getting five used compressors that work great as vacuum pumps, I have been using one for the last two years.
They are 110v refrigerant compressors from drinking fountains.
On mine I have it screwed down to a piece of wood, I have a plastic car fuel filter on the inlet to stop any junk from ruining the pump, and one on the outlet to keep the oil in. I also have a gage and a shut off valve inline to the mold. If you run the pump for a long time, over about an hour you will need a fan to keep it cool. They are very quiet, that makes it easy to find leaks in your bag. Occasionally I take the inlet filter off and suck a little refridgerant oil into the compressor.
I am asking $25.00 plus shipping for each. I am selling just the compressor, you will need to get the other parts. I will turn them on and make sure they work, other than that they are as is.
If your interested e-mail me at youngfg@yahoo.com. If I get more offers than I have compressors, whoever e-mailed first gets first chance.
Here is a picture of the one I am using
