This hame made vacuum pump will not work a refrigerator compressor can only pull a 28.5 or 40,000 microns to get water to turn into water wapor you must reach a vacuum level of 29,3 15,000 microns or lower preferrable 500 microns

I use one of these compressors for auto A/C work. They work fine as long as you keep them upright. I like the price best of all. I cut the screw-on fitting from a refrigerant can tap, drilled it out and soldered it onto the vacuum side tube. Now, my gauges can screw directly on the compressor.

probobly 30 inches mercury which would be about normal for a good deep vacuum pump

no such thing as 30 inches of vacuum, if you are using regular refrigeration gauges they are not accurate enough for high vacuum.

according to my Physics professors, the only way to an absolute vacuum is to get to aboslute zero, whitch truely hasn't been done. We've gotten with in tenths of a degree of minus 273 degrees. Even space is not, nor cannot be a true vacuum. So you can "suck" with your pumps all you want you'll still never get to the altimate ATP = nothing, zero

@bladder1010 True

@gtasound Okay, but closed-loop, or not, "vacuum" is always expressed relative to atmospheric pressure. "Standard" atmospheric pressure at sea-level here on Earth is generally taken to be 14.696 PSIA (absolute pressure, as opposed to gauge pressure, ie., 1 ATM). The argument was made by someone in the comments that they thought you could generate a vacuum of < 0 PSIA. You simply can't, no matter what. *That's* what I was talking about.
