Making A Fridge Compressor Into A Vacuum Pump

If you can find one go for a bigger ROTORY compressor.

I found one in a great big, old deep freezer. The freezer itself was at least 5 feet long, maybe 6.

I wish I could have taken the whole thing, I would have made a solar drier out of it or something, but I don't have the room.

Anyway the compressor is awesome. About twice the volume in size, but three to four times the CFM. Just what I was looking for.

Also I ran the pump for about 30 minutes under full load and it was barely warm to the touch.

It still did not go past the -27 inches of mercury, though. Fine with me.
